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. orcli. no. 28. 



This plant has heen imported from Sincapore hy 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. hijiorum^ of which it has 

 all the hahit ; but the lip is perfectly entire and not three- 

 lohed. 



193, ONCIDIUM microchilum (Bateman in litt.) ; pseudobiilbis lenticulari- 

 bus brevibus raonopbyllis, folio ensiformi carinato carnosissimo acute 

 quam scapus erectus versus apicem paniculatus qvtadruplo breviore, 

 sepalis liberis lateralibus longiils unguiculatis petalisque oblongis subun- 

 dulatis retusis, labello subrotundo cordato tridentato sepalis dupio bre-

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 0. crispum.

 losis oblongis compressis ancipitibus diphyllis, panicula angusta elongata 

 ramulis 3-fioris, sepalis liberis petalisque oblongo-lanceolatis acutis, 

 labelli cordati laciniis latei'alibus rotundatis grosse crenatis intermedia 

 multo brevioribus ; intermedise ungue basi lato apice angustiore lateribus 

 rectis lamina reniformi denticulata basi ipsa labelli duplo angustiore, 

 crista 5-dentata denticulis 2 anticis aucta, 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 Fitzwilliam, 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 

 accompanied by the following note. 



" This is quite a distinct and most beautiful species j it 

 forms festoons sometimes twice the length of the specimen 

 sent, and is much used in adorning altars. The beautifully
