Upper Guinea. Niger Delta: Brass, Barter, 1857! 
Specimens from the Nun River, on mangroves, Barter, 20106! and from Assin- 
Yan-Coomassie, Ashanti, Cummins, 87! apparently represent nearly allied species.

ligulate. Lip trilobed, crenulate, sheathing the column; side lobes 
semiovate ; front lobe ligulate, retuse, emarginate; spur ample,

‘West Tropical Africa. Without locality : cultivated specimens. 
Flowered in the collection of W. Wilson Saunders in 1872. Described as being very 
near L. capitata, Reich. f., but the sheaths of the inflorescence broader, the lip hastate 
at the base, and the spur shorter and stouter. I have not seen it. 
44. L. glomerata, Rolfe. Plant subacaulescent. Leaves linear- 
oblong, 3—+ in. long, 6—7 lin. broad ; apex shortly and unequally bilobed ; 
lobes obtuse or bidenticulate. Racemes subsessile, capitate, 1-1} in.

oblong, obtuse, concave, 4 in. long. Sepals and petals oblong, obtuse, 
3 lin. long. Lip suborbicular-oblong, obtuse, 3 lin. long; base sub- 
auriculate and clasping the column; spur stout, narrowly funnel-shaped 
at the base, the upper half subclavate-inflated, 4 lin. long. Column 
stout, 1 lin. long; pollinia with 2 slender stipites, and a linear-oblong

Upper Guinea. Sierra Leone: cultivated specimens, Schröder ! 
Originally flowered in the collection of Major Lendy, in 1885, and is said to have 
been introduced by Messrs. F. Sander & Co., through their collector, S. Schröder. A 
fruiting specimen from Sierra Leone, 4fzelius ! apparently belongs here.
