three-lobed ; the lateral lobes rounded, the intermediate one of a more 
yellow colour, fleshy and roughish, plates of the disk two only, con- 
cave, and separated by a raised line. CoLuMN roundish, acute; 
stigma margined ; clinandrium devoid of a margin, sloping. PoLLEN 
MASSES eight, arranged in pairs, and sessile on the gland, which is 
emarginate anteriorly. 
Poputar anp GeoeraApuicaL Notice. This species, of a genus 
of orchidaceous plants found as yet only in the east, is a native of Cey- 
lon. Of the other species, one Acanthephippium Javanicum is from 
Java, the second from the woods of Sylhet, Acanthephippium Sylhet- 
ense. All three are terrestrial in their place of growth, and not epi- 
phytes. It is often difficult to find objects to which to liken the vari- 
ous plants in this tribe, which are so singularly diversified in form ; 
but clustered as the flowers are in this species, they resemble a num- 
ber of gaudy plumaged young birds crowded in their nest, the unex- 
panded flowers being like those which have the beak closed, while the 
others seem like the nestlings gaping for food. 
InTRODUCTION ; WHERE GROWN; CuLTuRE. Sent in 1833, by 
Mr. Watson, superintendant of the Government Garden, at Peradenia, 
Ceylon, to the Horticultural Society. Our drawing was made in the 
now. greatly enlarged orchidaceous house of the Messrs. Loddiges, 
where it flowered in June, 1839. _It grows in a mixture of peat and _ 
sand, having a bottom of pot-shreds, to insure a free drainage. . It: 
exhibits the characteristics of tropical vegetation, in requiring a great 
deal of heat and moisture while growing, and a change to a cool and 
dry atmosphere, each year during the season of repose. 
DERIVATION OF THE 
ACANTHEPHIPPIUM, from Axay@oc, AcantHos, a thorn or spine, and EgiTrmov 
EPHrpPion, a saddle, but what connection this has with Blume’s species 
seems incom preliensible. Bicotor two-coloured, from the party-coloured 
flower.
