oblongis loratis obtusis subemarginatis, scapis foliis æqualibus, floribus 
umbellatis, sepalis lateralibus obliquis falcatis obtusis majoribus supremo 
rotundato nano, petalis ovatis obtusis, labello cordato ovato complicato

The mountains of India yield this little Bolbophyl. Dr. 
Wallich’s collectors found it in Nepal in 1821 ; it was one 
of the plants collected in the Khasiya hills, by Mr. Gibson, 
for his Grace the Duke of Devonshire, and flowered at 
Chatsworth in 1838; and now has been reintroduced by 
Messrs. Loddiges, with whom our drawing was made in 
September, 1844. 
The pale straw-coloured flowers spotted with purple, are 
rather large, and for a Bolbophyl, pretty. The column has 
two long horns, which have had a single tooth on the upper side 
in all the specimens we have examined. The pollen-masses 
are, as is customary in the diee: of very unequal size, the 
front pair almost concealing that behind; and in this case are 
held together by some soft mucus, which resembles the gland 
of the Vandeous Orchids, but is destitute of its firmness and 
permanency. 
Like many others of the same genus this species may 
either be potted in turfy heath-mould in the usual way, or it 
may be tied to a block of wood and suspended to the rafter. 
It is a stove plant which requires a humid atmosphere, and
