 Delta : Brass, Barter, 47 ! Great Batanga, Braun, 17 (ex Kranzlin). 



^o-wer 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.

 rather slender. Leaves petiolate or oblong-lanceolate, acuminate, 

 6-7 in. long, 1-1 J in. broad ; petioles f lin. long. Racemes 1 in. long. 

 Bracts ovate-oblong, subobfcuse, lJ-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, 

 2h 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. 



Ibo-wer Guinea. Gaboon : Province of Munda, frequent in woods, ])ut seldom

Larger altogether than the preceding, with the lip differently shaped, and the 

 crest reduced to a few scaly appendages. 



3. V. cucullata, Krdnzl.in Mittheil. Deutsch. Schutzg. ii. (1889), 

 161. Leaves oblong, acuminate, obliquely cordate at the base, shortly 

 petiolate, 4-6 in. long, li-2J in. broad. Rhachis of raceme rather 

 stout, rarely bi'anched at the base. Bracts squamiform, triangular. 

 Flowers 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 

 lamella?, 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. raxuosa, Rolfe in Journ, Linn. Soc. xxxii. 457. Stem rather 

 slender. Leaves petiolate, oblong or elliptic-oblong, shortly acuminate 

 and subobtuse, 4-6 in. long. 1-2J in. broad ; petioles |-| in. long. 

 Racemes lJ-2 in. long, often somewhat branched at the base. Bracts 

 ovate, subobtuse, 1-2 lin. long. Sepals and petals oblong-lanceolate, 

 subacute, subequal, 10-12 lin. long. Lip deeply trilobed, 7-8 lin. long; 

 side lobes broader than long; front lobe oblong, subacute, margin 

 crenulate, reflexed, plicate ; crest composed of several scales. Column
