from specimens sent from the Botanic Garden of the Mauritius, 
procured no doubt from Madagascar. I find flowers of it in 
Lindley’s herbarium, obtained from Kew in 1852, and well 
described in Mss. I should add that he changed the name 
(possibly through inadvertence) from Acranthes in the 
Botanical Register to Acranthus in the ‘“ Genera et Species 
Orchidearum,” which latter spelling is retained in his Vege- 
table Kingdom, and hence adopted here. The plant here 
figured was sent to Kew by Mr. Horne of the Mauritius 
Garden. 
Descr. Leaves equitant, five to eight inches long by three- 
quarters to one inch broad, ovate, recurved, keeled, not un- 
dulate, deeply very unequally obtusely 2-lobed at the tip, 
sheathing portion short, deep green above, paler beneath. 
Peduncle six inches long, very slender, 1-2-flowered at the 
apex, with four to six slender brown appressed sheaths which 
are shorter than the internodes. Mowers nearly two inches in 
diameter across the tips of the sepals, wholly yellow green, 
the tips of the perianth-segments, which are all caudate acu- 
minate, of a deeper yellow green. Dorsal sepal with a 
broadly ovate base; lateral much larger, deflexed, the very 
broad base produced into a gibbous lobe on the lower side. 
Petals similar to the dorsal sepal. Lip equalling the lateral 
sepals, recurved, base quadrate-oblong, abruptly terminating 
in a triangular caudate acuminate lobe, with a notch at its 
base on each side, disk slightly pubescent, basal angles some- 
what recurved ; spura very short inflated oblong obtuse sac.—
