134. DR. LINDLEY ON WEST AFRICAN TROPICAL ORCHIDS. 
Lip purple, other parts rose-colour. Tubers like kidney potatoes, in 
chains nearly a yard long ; common about Abbeokuta.” (3331) Barter. 
A fine species, readily known by the two great processes standing 
on either side of the orifice of its little conical spur and terminating 
the two sides of three glandular lines. 
CYMBIDIUM, Swartz. 
l. C. ADENOGLOSSUM ; foliis hysteranthiis, scapi vaginis 3 ventricosis 
obtusis, racemo paucifloro bracteis angustissimis linearibus, sepalis ~ 
secundis basi productis cornutis petalisque minoribus lanceolatis acu- 
minatis, labello trilobo medio carnoso striato : lobis lateralibus cunei- 
formibus intermedio ovato apiculato rugoso per axin serie duplici tu-

* Nupe, 1859," Barter. 
Nearly related to the Cape Cymbidium tabulare, from which 
its ventricose stem-sheaths and very different lip abundantly di- 
stinguish it. The two lamell» usually found in the axis of the lip 
of this genus, when strictly limited, are here confluent into a raised 
striated ridge.

2. A.? sp. 
“R. Nun.” Label lost. Barter. 
A plant with the distichous leaves of some Dendrobium, and 
small few-flowered axillary spikes. All the flowers fallen. 
There is another plant in the collection also without flowers 
(“ On Mangroves, R. Nun,” 2106, Barter) which seems to belong 
to this genus. And Mann sends a third, equally indeterminable 
(Nun, 524).
