40 PROFESSOR LINDLEY’S CONTRIBUTIONS TO 
“linia 4, arctissime geminata, æqualia, aciei falcis per ligulas 2 
elasticas adnata. Glandula longissima, cartilaginea, sagittata. 
2329. U. oBTUSIFOLIA ; foliis latis loratis obtusis oblique bilobis, pe- 
talis 3-veniis, labelli margine utrinque 1- dentato apice retrorsum 
bidentato, calcare apice inflato. 
Base of Khasija, J. D. H. & T. T. (194). 
Flowers twice as large as in the following. 
233. U. ACUMINATA ; foliis lanceolatis oblique acuminatis obtusis pe- 
talorum venis З cis apicem: evanescentibus, labelli 3-lobi lobis late- 
ralibus rotundatis intermedio brevi tereti carnoso obtuso, calcare 
acuminato. 
Assam and Khasija, Griffith ; base of Khasija, J. D. Н. & T. T. (193). 
Flowers much smaller than in the last. Spur of lip tapering to 
the point. Petals 3-veined, as in U. obtusifolia ; 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 different 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 were 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 
ihe apparent back of the column, suddenly contracts into а 
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. 
ANGRZECUM, Thouars. 
. The only Indian species that I have seen of this African genus 
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. 
Very 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 examinahble state.
