108 SOUTH NIGERIAN PLANTS 



thick is attached by numerous distichously spreading branched roots, 

 which penetrate the covering of the short persistent sheathing leaf- 

 bases. Leaves on the larger specimen (n. 915) 20-22-5 cm. long by 

 4-4 • 5 cm. broad, narrowing more or less rapidly downwards ; on the 

 smaller specimen (n. 914) 15-5-20 cm. long, 2-3 cm. broad. Bacemes 

 to 25 cm. long, two developing successively in the same leaf-axil. 

 Bracts 1-5 mm. long, broadly cup-shaped. Sepals 6-5-7 mm. long 

 by 2-2-3 mm. broad. Betals 5 mm. by 1-3 mm.; lip 6 mm. by 

 4 - 5 mm. ; spur 7 mm. by 1 - 5 mm. Column 2 • 3 mm. long ; rostellum 

 barelv 1 mm. long. 



Allied to L. bidens Rolfe, which it resembles in habit, but is 

 distinguished by its upwardly broadening leaves, larger flowers with 

 longer non-clavate spur and other details.

Oban ; n. 941. 



A tiny plant, the single specimen 3-5 cm. high, with four shortly 

 ensiform leaves about 1-5 cm. long and barely -4 mm. broad, crowded 

 on the very short stem from which springs a tuft of filiform roots. 

 Sterile portion of scape with five nodes, sheathing bracts 2-2 cm. 

 long, narrowing and acute above the middle. Spike 1-7 cm. long. 

 Bracts 2 mm. long. Flowers 2 mm. long, excluding ovary with 

 pedicel which together are a little over 1 mm. long. Dorsal sejml 

 1-8 mm. long by "75 mm. broad when flattened; lateral sepals 2 mm. 

 by -7mm. Petals 1-6 mm. by -75 mm.; lip 1 6 nun. long; spur 

 1 • 7 mm. Column ■ 6 mm. long. 



Evidently near L. Zenheri Kriinzl. from the Cameroons, a plant 

 which I have not seen, but which differs (from the description) in its 

 much longer (4-5 cm.) proportionately narrower leaves, the biapicu- 

 late lateral sepals, and ovate-oblong lip. 



Vanilla nigeriea Rendle sp. nev. Planta scandens caule 

 foliate verruculoso ; foliis petielatis e basi rotundata lineari- 

 oblengis acuminatis, petiole brevi late canaliculate ; racemo

 hradeis late evatis subacutis ; floribns albidis, sepalis et petalis

Oban ; n. 776. 



Leaves 17-24 cm. long, 4-4-5 cm. broad; petiole 1-5 cm. long.
