variety from Bolivia (487), with the inside of the sepals and 
the tips of the petals stained with purple. It does not other- 
wise differ from the original form of the species. 
192. DENDROBIUM gemellum. Lindl. gen. & sp. orch. no. 28. 
This plant, has been imported from Sincapore by Messrs. 
Loddiges, and forms their no. 158 of Mr. Cuming’s collections. 
It is a long-stemmed grassy-leaved plant, with small pale 
yellowish green flowers, growing in pairs from short rigid 
two-valved truncated compressed spathes, placed opposite the | 
leaves. In this respect it is like D. biflorum, of which it has 
all the habit ; but the lip is perfectly entire and not three- 
lobed. 
193. ONCIDIUM microchilum (Bateman in litt.); pseudobulbis lenticulari- 
bus brevibus monophyllis, folio ensiformi carinato carnosissimo acuto 
quam scapus erectus versus apicem paniculatus guadruplô breviore, 
sepalis liberis lateralibus longiús unguiculatis petalisque oblongis subun- 
dulatis retusis, labello subrotundo cordato tridentato sepalis duplô bre- 
viore, cristà subrotundá 5-crenatá dente intermedio labelli parüm bre- 
viore, columnx nanz alis oblique truncatis. 
Of this curious Oncidium, sent by Mr. Skinner from 
Guatemala, Mr. Bateman possesses live specimens. He truly 
calls it a most distinct and remarkable species; the smallness 
of its lip, which is not half so long as the lateral sepals, being 
a singular feature. The leaves are about eight inches long; 
the flowers the colour of O. crispum. 
194. ONCIDIUM Wentworthianum (Bateman in litt.); pseudobulbis nebu- 
losis oblongis compressis ancipitibus diphyllis, paniculà angustà elongatà 
ramulis 3-floris, sepalis liberis petalisque oblongo-lanceolatis acutis, 
labelli cordati laciniis lateralibus rotundatis grossé crenatis intermedia 
multó brevioribus; intermedise ungue basi lato apice angustiore lateribus 
rectis lamina reniformi denticulatá basi ipsà labelli duplo angustiore, 
cristà 5-dentatâ denticulis 2 anticis auctá, columnee alis erosis brevibus. 
Mr. Bateman has favoured me with a fine specimen of 
this beautiful species, which he has received from Mr. Skinner 
and named after Lord Fitzwiliam, and which approaches 
O. Baueri and altissimum in its general appearance. The 
flowers are however very differently shaped, and richly stained 
with crimson upon a yellow ground. The specimen was 
aecompanied by the following note. 
“This is quite a distinct and most beautiful species; it 
forms festoons sometimes twice the length of the specimen 
sent, and is much used in adorning altars. The beautifully
