40 PEorESSOE lindlet's conteibtjtions to 



linia 4, arctissime geminata, sequdia, aciei falcis per ligulas 2 

 elasticas adnata. Glandiila longissima, cartilaginea, sagittata. 



232. U. OBTUSIFOLIA ; foliis latis loratis obtusis oblique bilobis, pe- 

 talis 3-veniis, labelli margine utrinque 1-dentato a])ice retrorsum 

 bidentato, calcare a pice inflate. 



Base of Khasija, /. D. H, 8f T. T. (194). 

 Flowers twice as large as in the following. 



233. U. acuminata; foliis. lanceolatis oblique acuminatis obtusis pe- 

 talorum venis 3 eis apicem evaneseentibus, labelli 3-lobi lobis late- 

 ralibus rotundatis intermedio brevi tereti carnoso obtuso, calcare 

 acuminato. 



Assam and Khasija, Griffith; base of Khasija, J. D. H. ^ T. T. (193). 



Mowers much smaller than in the last. Spur of lip tapering to 

 the point. Petals 3-veined, as in IT, obtusifoUa ; but the veins 

 stop short of the blunt end, instead of running out. 



Of this very curious genus the two species exactly agree in their 

 column and its parts, although so diflferent in the details of the 

 petals and lip. I know of no parallel to the terete column, bent 

 down till the stigma is brought into a horizonal position, looking 

 down as it w^ere into the spur ; or to the singular caudicle, which 

 after expanding laterally from its narrow point, and bending down 

 its sides so as to form an arch over the anther-bed, which is here 

 the apparent back of the column, suddenly contracts into a 

 process like a billhook, the edge of which faces the front and 

 bears the pollen-masses. The abruptly hooked lip, which has sug- 

 gested the name, is itself unlike anything among Indian Orchids. 



Ange^cum, Thouars. 

 The only Indian species that I have seen of this African genua 

 is the following : — 



234. A. Zeylanicum ; subacaule, foliis lanceolato-loratis lobo altero 

 apicis elongato subfalcato, racemis filiformibus paucifloris duplo lon- 

 gioribus, sepalis petalisque acuminatis sequalibus, labello cochleato 

 acuminato calcare horizontali clavato. 



Ceylon, at Narawelle, Champion. 



Yery like A. caulescens ; but the leaves are broad, 10 inches long, 

 with one of the terminal lobes much longer than the other, and 

 the spur not inflated at the point. I have not seen the column 

 in an examinable state.
