MARCH, 1912.] THE ORCHID. REVIEW. 77 
grows in abundance. The only other species of this genus known, B.. 
domingensis, is confined to a limited area in the mountains above New 
Castle. Both are very desirable Orchids, the former having crimson- 
coloured flowers, the latter rosy lilac, blended with white. 
A week was spent in collecting at the Cinchona plantations, at 5,000- 
feet altitude, and this place is fourteen miles by mountain trail from Gordon 
Town. Soon after leaving Gordon Town the first Orchids were found, 
Epidendrum cochleatum was the most common, often found on rocks,. 
stony banks, and trees. E. fragrans was also abundant, and often in full 
bloom. The tall and stately E. verrucosum was also found in bloom. 
This is a bulbless Orchid with reed-like stems often four or five feet in: 
height. The long diffuse panicles of yellowish green flowers, while not 
showy, were highly interesting. On the banks of the Yallahs River, 
growing on small trees, were found several fine plants of Oncidium luridum 
and Epidendrum difforme, usually known as E. umbellatum. From the 
Yallahs River it is a climb of 2,500 feet to Cinchona. Along the trail 
numerous Orchids were found, including a fine specimen of Schomburgkia 
Lyonsii, Isochilus linearis, and several species of Pleurothallis and Stelis. 
From Cinchona several long excursions were made, including a tramp: 
through the noted tree-fern forest. Epidendrums were common along 
these mountain. trails, and many were collected, including E. ramosum, 
also Lepanthes divaricata and Dichza glauca. Several stately plants of 
Phaius grandifolius were found growing in the rich humus on shady banks. 
This Orchid was introduced many years ago from China, its native habitat, 
and has become completely naturalised. It is now found in almost all 
parts of the island. 
Among the Orchids of Jamaica the most beautiful are: Lelia 
monophylla, Schomburgkia Lyonsii, Broughtonia domingensis, Oncidium 
luridum, O. leuchochilum, O. pulchellum, and Arpophyllum giganteum. 
There are many peculiar facts regarding the Orchids of Jamaica of special 
interest to the student of plant distribution, and also problems relating to 
the origin of species that merit the attention of the Evolutionist. 
The paper concludes with a short summary of the Orchids of Jamaica, 
from the recently published Flora. Of the sixty-one genera found on the 
island, twenty-eight are represented by a single species each. Of these the 
most interesting are: Lelia, Schomburgkia, Hormidium, Tetramicra,. 
Calanthe, Phaius, Eulophia, Govenia, Lycaste, Trichopilia, Zygopetalum, 
and Harrisella. The last is named in honour of Mr. William Harris, who 
‘has contributed so much te our knowledge of the Orchids of Jamaica. One 
genus, Homalopetalum, is indigenous. Of the 194 species, seventy-three 
are not found elsewhere. Of the genus Lepanthes there are nineteem 
species, of which seventeen are endemic. These are small alpine plants,.
