Upper Guinea. Without locality, cultivated specimens, Loddiges! Niger 
Delta: Brass, Barter, 47! Great Batanga, Braun, 17 (ex Kranzlin). 
Lower Guinea. Gaboon: Mount John, Kongui River, Mann, 1881! 
Originally described from a specimen which flowered with Messrs, Loddiges. 
Unfortunately the sepals and petals are not described by Lindley, nor are they present. 
on any of the specimens, though Lindley has carefully preserved and drawn the other 
parts of the flower. 
2. V. acuminata, Rolfe in Journ. Linn. Soc. xxxii. 456. Stem 
rather slender. Leaves petiolate or oblong-lanceolate, acuminate, 
6-7 in. long, 1-1} in. broad; petioles 2 lin. long. Racemes 1 in. long. 
Bracts ovate-oblong, subobtuse, 14-4 lin. long. Sepals 10-12 lin. 
long; dorsal lanceolate, acute, 3 lin. broad; lateral lanceolate-oblong, 
acute, 4 lin. broad. Petals falcate-lanceolate, acute, 9-10 lin. long, 
2} lin, broad. Lip deeply trilobed, 7-8 lin. long ; side lobes roundish- 
oblong, obtuse; front lobe oblong, obtuse or apiculate; disc with a 
small central crest composed of a few retrorse scales. Column clavate, 
6-7 lin. long. 
Lower Guinea. Gaboon: Province of Munda, frequent in woods, but seldom 
flowers, Soyaux, 134 ! 
Larger altogether than the preceding, with the lip differently shaped, and the 
crest reduced to a few scaly appendages. 
3. V. cucullata, Kränzl. in Mittheil. Deutsch. Schutzg. ii. (1889), 
161. Leaves oblong, acuminate, obliquely cordate at the base, shortly 
petiolate, 4-6 in. long, 1}-2} in. broad. Rhachis of raceme rather 
stout, rarely branched at the base. Bracts squamiform, triangular. 
owers 1 in. long. Lateral sepals ovate, slightly oblique; dorsal 
oblong, rather shorter than the lateral. Petals very similar to the 
sepals, Lip ovate, nearly triangular, acute; disc with two linear 
lamelle, one behind the other, hyaline and fimbriate at the apex, 
reflexed and appressed to the limb. Column curved, the basal third 
_ united to the lip.—Rolfe in Journ. Linn. Soc. xxxii, 456. 
Upper Guinea. South Cameroons, Braun, 4. 
Only known to me from the original description, but apparently allied to the pre- 
ceding. The lip is less united to the column, and apparently different in shape. 
4. V. ramosa, Rolfe in Journ. Linn. Soc. xxxii. 457. Stem rather 
slender. Leaves petiolate, oblong or elliptic-oblong, shortly acuminate 
and subobtuse, 4-6 in. long. 1-2} in. broad; petioles }—3 in. long. 
cemes 14-2 in. long, often somewhat branched at the base. Bracts
