Trachycarpus latisectus - The Windamere Palm
'Broad leaf segments' is the uninspiring translation
of its name. However, it's a beautiful species, difficult in its
early years, but well worth persevering with.

It was Henry Noltie of the Royal Botanic Garden,
Edinburgh, who first alerted us to the existence of a strange Trachycarpus
in Darjeeling, India. He had been in the area during the Edinburgh
Sikkim Expedition in 1992 and had noticed a pair of these trees
in the garden of the famous Windamere Hotel. He took photographs
and collected herbarium specimens, but our later examination of
these at Kew provided no clue as to the identity of this palm, other
than that it appeared indeed to be a species of Trachycarpus.
Several possibilities came to mind: Could they be
some kind of hybrid? Or were these the 'real' Trachycarpus martianus
of Nepal? (For further reference see Noltie, H.J. 1994. Flora
of Bhutan Vol. 3, part 1. Edinburgh and Spanner, T. W., H.
J. Noltie and M. Gibbons. 1997. A new species of Trachycarpus
(Palmae) from West Bengal, India, Edinburgh Journal
of Botany 54:257-259). Further, were those we had encountered
the previous year in Meghalaya, India (see Gibbons, M. and T. Spanner.
1994. Trachycarpus martianus, Principes
38:89-94.), actually 'Trachycarpus khasyana' as they were originally
described by Griffith in Palms of British East India
(1850), and, as Griffith believed, a separate species?
There was only one way to find the answers to these
questions and that was to visit the palms to see for ourselves.
Thus, in November,1994, during our 'Trachycarpus Asia' expedition,
we simply decided to take a side trip to see if we could throw any
light on the identity of these mysterious palms.
First, we spent a week in Nepal where we saw many
Trachycarpus martianus, both in the wild and in cultivation. It
was clear from a close examination of these palms that Trachycarpus
martianus and T. khasianus are indeed one and the same species,
so the theory could no longer hold water. Having answered one of
our questions, we headed off for Darjeeling to see these unidentified
palms for ourselves.
Darjeeling is a most lovely town, an old hill station
from the days of the British Empire, still with many colonial buildings
and much architecture intact, though in many cases, fading. We were
travelling by taxi, having started from Biratnagar on the Nepalese
border, and after passing through the town of Siliguri, we began
to climb. This hilly road is accompanied from bottom to top by the
narrow gauge railway line of the 'Toy Train,' a true miniature locomotive
with carriages that brings both passengers and goods to and from
Darjeeling. The journey, though fun, is rather long, taking about
eight hours. Our Formula One taxi driver, however, took just two.
We reached the Windamere Hotel at 11pm with high hopes
as we had read the many accolades and complimentary remarks about
it in our guide book ('best porridge in India' for example). Though
we had no booking and the hotel was full, a comfortable room was
somehow found for us, and we were supplied with hot-water bottles
as at this altitude, 2200m above sea level, it was distinctly chilly,
with a slight mist worthy of the lake from which the hotel takes
its name. Notwithstanding this, we couldn't wait for the 'boy' who
carried up our bags to go so we could explore the grounds and the
Trachycarpus waiting for us there.
If we had any expectation of being able to identify
these two big palms at a single glance, we were much mistaken, and
we stood there for some time in the dark, examining them by torchlight.
Although a litte wind damaged, they were very robust and quite stately
looking trees with smooth grey trunks and large leaves, resembling
those of some Livistona more than any Trachycarpus we knew. Eventually
we had to admit that we were stumped; we simply knew everything
that they weren't. Further inspection by daylight the following
morning after breakfast (the promised porridge, eggs and bacon)
only served to confuse us more and we continued to be at a loss
as to what they could be.
During our brief stay in this attractive town we saw
many other Trachycarpus, both in the town itself and in the rather
disappointing and much neglected Lloyd Botanic Gardens. These were,
without exception, T. fortunei, and despite T. martianus having
been reported as growing here (for further reference see Shri Dar,
1994. Hunting Out The Trachycarpus martianus, The
Palm Journal 118:26-30), a thorough search revealed not a
We left Darjeeling still scratching our heads, and
drove to Gangtok in Sikkim, and from there down to Kalimpong. On
the way we saw many Phoenix rupicola and Wallichia disticha, both
'special' palms to us which we were delighted to find.
On arrival in Kalimpong, another pleasant town, we
checked in at the Himalayan Hotel and our surprise can only be imagined
when, in the garden, we saw another of the Windamere palms! The
answer to the conundrum came in a flash: this was a new and undescribed
species of Trachycarpus, quite distinct and different from all others.
In the following few days we were to see many more, all, it must
be said, in cultivation, generally in gardens in and around the
town. They were indeed splendid trees with slender trunks to about
8m tall, occasionally even taller. Their numerous, comparatively
large, leathery and, for a Trachycarpus, shallowly divided, nearly
circular fan-leaves are carried on long, robust, unarmed petioles
and form an upright, open crown. After dying, the leaves hang down
in a small skirt below the crown and eventually drop, together with
the coarse, fibrous leafsheath, revealing a smooth, light grey trunk.
The leaf is also most notable for its rather wide segments producing
a slightly convoluted leaf profile. Some of the segments in the
leafblade, particularly the lower ones, are fused for nearly their
entire length, in groups of 2 to 4. Many of the female trees carried
bunches of oval, flattened, yellowish-brown and eventually blueish-black
fruit. The seeds resembled those of T. martianus, albeit slightly
larger, proving the two to be closely related.
The Trachycarpus from this area were certainly not
missed by the early plant hunters and have been mentioned by various
authors, though always under the name of T. martianus. We asked
ourselves, how could the unique characteristics, which distinguish
them from T. martianus from early age on, have been missed, when
they had been seen by eminent botanists both in the field and later,
as herbarium specimens? Under Trachycarpus martianus, Beccari tells
us in The Annals of the Royal Botanic Gardens, Calcutta
(1931) that ...stunted plants have been encountered by Gamble
on the Rissom (actually Rissisom; mountain) near Dumsong beyond
Darjeeling, at about 1970m, and (by Brandis, in 1879) on the Dumsong
Hills at about 2400m. Further, Beccari says that C.
B. Clarke collected ... a young plant of Tr. martiana in Sikkim
at Rungbong at about 1,200m elevation. Of these two latter
collections Beccari states that the leaves of the young plants
are of a rather herbaceous texture (and) have few segments.
Of his own collection, Gamble, in A Manual of Indian Timbers
(1902) writes, The writer has once found small plants of what
is probably this palm (T. martianus) on Rissoom, near Dumsong....
It seems clear that these collections were not of T. martianus at
all but were of the same species as we had now seen in Darjeeling
and Kalimpong, and the fact that it was new and different had been
missed. However, when reading between the lines, it does seem that
perhaps they were not 100% convinced of the true identity of the
plants they had collected. Later examination of some of their herbarium
specimens now at Kew confirmed our suspicions: they were identical
to those we had come across in the field.
Whilst we were delighted to find this palm in so many
gardens in Kalimpong and were certain about its identity, we felt
we really had to try to locate a population in the wild before formally
describing it as a new species. This was to take another twelve
months, during which time we searched high and low in Sikkim and
in the Kalimpong district for these palms.
Just a week before our return trip to India in October,
1995, a small population had been found some 20 miles east of Kalimpong,
growing on the slope of a steep valley in the Dumsong range of hills
near where it had originally been recorded (as T . martianus). We
travelled back, looking forward with great excitement to what was
to be a highlight of the trip.
We had allowed ourselves considerably more time than
in the previous year and before our visit to the palms' habitat
we spent a day examining in greater detail many of the palms in
the town, becoming increasingly optimistic about their attractiveness
and suitability for cultivation in other temperate climate areas
of the world. Then, finally, the great day arrived and we set off
by jeep to see the palms in nature. We travelled east for some 15
miles, then turned off the 'main' road onto a narrow and extremely
bumpy track through villages and rice and millet paddies. Finally
we could drive no further and proceeded on foot. It wasn't long
before we saw the first of a good number of Trachycarpus palms,
loosely scattered over a rather steep grassy slope and cliffs overlooking
the Relli River, always inhabiting the most precipitous places (Photo
8). Whereas the day before the weather had been cool and misty,
today there was hardly a cloud in the sky, and the leaves of our
palms were brightly glistening in the mid-morning sun. The palms
themselves seemed rather stunted compared with those we had seen
in cultivation and their habitat much degraded. We soon learned
that the entire slope had once been densely covered with monsoonal
forest, of which only a few crippled trees now remained. It needs
no great imagination to realize that the palms' habitat used to
be much more humid and calm, protected, at least in part, under
a canopy of larger trees. Without this canopy the site seemed too
dry for them to sucessfully set seed and for seedlings to establish.
Even with this grim reality, it was a most exciting place to visit
and we were soon scrambling up and down the slope, taking photographs
and measuring the palms. After a happy day we returned to Kalimpong,
and then, regretfully, back to Europe. The whole area, including
Sikkim proper, is a rich one for palm enthusiasts and we will certainly
The following description of this new species was
first published in The Edinburgh Journal of Botany and
is reproduced here in a slightly adapted version to bring it to
the attention of a wider audience. Growers and enthusiasts might
like to note that seeds and seedlings of this species have been
distributed as T. sikkimensis in the recent past (see

The specific epithet 'latisectus' (with wide segments)
was chosen for this species unusually wide leaf segments,
a characteristic through which it usually can be easily identified
and distinguished from other members of the genus.
Distribution and Conservation Status:
INDIA: in the foothills of the Sikkim Himalayas in extreme northeastern
West Bengal (Kalimpong) and southern Sikkim, between about 1200m
and 2440m elevation (Gamble 1902, Cowan 1929, Beccari 1931).
In Sikkim and two locations in West Bengal, the palm has apparently
not been recorded for at least 60 years and could not be relocated
to date. It is under immediate threat of extinction in the wild
with only about 50 plants surviving in what may be its last remaining
site on a steep, deforested slope on rocky soil at Mirik Busty on
the Relli River between 1300 and 1400m, where it is unable to reproduce.
Unless immediate action is taken, the chances for its survival in
the wild seem bleak.
Venacular names and Uses:
The following local names have been recorded: Talaerkop, punkah,
tarika, purbung, bhotay kucho. The stems have reportedly been used
Trachycarpus latisectus is a frequently cultivated ornamental in
Kalimpong and environs and its future in cultivation there seems
fairly secure. Young plants are commonly encountered.
Being cold-hardy as well as fast and easy to grow, it has good prospects
of becoming a popular ornamental for temperate and subtropical regions.
Seeds from cultivated trees around Kalimpong have been distributed
to many growers around the world during recent years as Trachycarpus
sikkimensis, a provisional name of no botanical standing,
relating to the area of its historical distribution being floristically
and geographically known as the 'Sikkim Himalayas'.
Although many growers and enthusiasts may have become familiar with
the name T. sikkimensis in the meantime, we have decided
for a number of reasons not to use this name as the specific epithet
of this new species and hope we will not have added too much to
the confusion already surrounding this genus.
Note: There is no recent taxonomic treatment of the genus Trachycarpus
(but see Beccari 1931, Kimnach 1977 and Gibbons 1996). Relationships
of T. latiscetus will be dealt with in a conspectus of the whole
genus, which will appear in a future publication of Palms
(formerly Principes), the Journal of the International
We would like to express our appreciation to Henry Noltie of the
Royal Botanic Gardens, Edinburgh, co-author in our formal description
of this species in the Edinburgh Journal of Botany.
Very special thanks are due to Dr. John Dransfield of the Royal
Botanic Gardens Herbarium, Kew for his unfailing enthusiasm and
encouragement and for his critical review of this manuscript.
