long. Leaves twin, narrow-oblong, 3 in. long, i in. broad. Scape 
slender, wiry, erect, about twice as long as the leaves, with a few loose 
scattered sheathing scales. Spike short, crowning the scape ; bracts 
ovate, concealing the buds. Lateral sepals connate throughout ; upper 
one shorter and narrower. Petals subulate. Labellum ovate, acute, 
truncate at base, thickened in the middle. Teeth of the column directed 
almost vertically upwards, its produced base short. Capsule ovoid, i 
in. long. Lindl. Gen. and Sp. Orch. 52. Rich. Orch. Maur. 64.

10. B. pendulum, Thouars, Orch. Afr. t. 104. Pseudobulbs sub- 
globular, sulcate, less than \ in. in length. Leaves twin, oblong, 
emarginate, 2 in. long, ■£— §• in. broad. Scape short, nodding, bearing a 
short dense flower-spike. Sepals ovate, acute, the upper narrower 
than the lateral. Petals oblong. Labellum broadly ovate, obtuse, 
truncate at base. Lindl. Gen. and Sp. Orch. 52 ; Rich. Orch. Maur. 64.

have seen no specimen. 
11. B. pusillum, Thouars, Orch. Afr. t. 102. Pseudobulbs sub- 
globular, scarcely i in. long. Leaves solitary, obovate or oblong, 
emarginate, scarcely longer than the pseudobulbs. Scape much longer 
than the leaves, clothed with numerous sheathing scales, dilated above ; 
flowers partially immersed in the dilated portion of the scape. Lateral 
sepals apparently connate about half the way up ; upper sepal ovate, 
acuminate. Petals labellum and column as in B. clavatum , but all the 
floral parts are much smaller than are those of that species. Lindl.

Mauritius, on trees in dark forests towards the centre of the island, Bojer. Also 
Bourbon. I have seen no specimen. 
Thouars (Orch. Afr. t. 101) has a singular figure of a plant which he. calls Bulb • 
ophyllum gracile : its pseudobulbs arc apparently much laterally compressed, the 
leaves are nearly 5£ in. long, and the scape more than twice that length, with large 
loose sheathing scales, bears a long sparsely-flowered spike. There is no dissection 
of the flower given by Thouars, so that it is deemed advisable not to include it in 
the Flora ; the plant was never seen by Bojer.
