88. SACCOLABIUM gemmatum. 



S. gemmation ; foliis distichis semiteretibus canalicnlatis subtortis apice insqua- 

 liter tridentatis, spica ramosa, floribus minutis carnosis, sepalis conniventi- 

 bus ovatis obtusis lateralibus multo majoribus, petalis brevioribus subrotun- 

 dis, labello carnoso ovato crystallino dorso tuberculato marginibus calcaris 

 conici penduli dilatatis carnosis rotundatis, columna brevissima, apice 

 antheree hemispha^ricae reflexo. 



This new species was discovered in 1837, on the Khoseea 

 hills of India by Mr. Gibson, and was brought by him to 

 the Duke of Devonshire, in whose collection at Chats worth 

 it flowered in May. The blossoms are the smallest of the 

 genus, not being larger than a grain of mustard-seed, but 

 the finest amethysts are not of a more brilliant purple, and 

 the tips of the labellum and sepals are quite white. 



89. EPIDENDRUM vesicatum. 



E. vesicatum ; caule elongato, foliis inflatis equitantibus carinatis acutis glaucis, 

 floribus terminalibus fasciculatis carnosis foliis vix longioribus, sepalis lineari- 

 oblongis acutis petalis conformibus angustioribus, labello subrotundo cordato 

 linea media tuberculisque duobus basilaribus elevatis, collo ovarii medio 

 vesicato. 



A curious Brazilian species, for which I am indebted to 

 Messrs. Loddiges. In habit it approaches E. equitans, but 

 in the structure of both flowers and leaves it is widely dif- 

 ferent. The latter are covered with a glaucous bloom, im- 

 bricated, and more like inflated carinate bracts than true 

 leaves. The flowers are greenish white, and offer some 

 analogy with those of Physinga, but are in reality different 

 from those of a genuine Epidendrum in nothing, except the 

 neck of the ovary having an elevated semi-transparent 

 blister near its middle. This blister is in fact the lower 

 extremity of the cuniculus of the flower. 



90. ODONTOGLOSSUM cordatum. 



O. cordatum ; scapo ascendente radicali, sepalis lineari-lanceolatis acuminatis 

 petalis conformibus longioribus, labello cordato acuminato unguis lamella 

 carnosa apice biloba basi bicristata, columna pubescente clavata. 



As yet only a small specimen of this has flowered with 

 George Barker, Esq. of Birmingham, who imported it from
