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 em. long by 
4-4:5 cm. broad, narrowing more or less rapidly downwards; on the 
smaller specimen (n. 914) 15°5-20 em. long, 2-3 em. broad. Racemes 
to 25 em. 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. Petals 5 mm. by 1:8 mm.; lip 6 mm. by 
4:5 mm.; spur 7mm.byl'’5mm. Column 2:3 mm. long; rostellum 
barely 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 em. 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 em. 
long, narrowing and acute above the middle. Spike 1*7 cm. long. 
Bracts 2 mm. long. Flowers 2 mm. long, exeluding ovary with 
pedicel which together are a little over 1 mm. long. Dorsal sepal 
1:8 mm. long by "75 mm. broad when flattened ; lateral sepals 2 mm. 
by ‘7 mm. Petals 1:6 mm. by '75 mm.; lip 1 6 mm. long; spur 
1:7 mm. Column ‘6 mm. long. 
Evidently near L. Zenkeri Krünzl. from the Cameroons, a plant 
which I have not seen, but which differs (from the description) in its 
much longer (4-5 em.) proportionately narrower leaves, the biapicu- 
late lateral sepals, and ovate-oblong lip. 
Vanilla nigeriea Rendle sp. nov. Planta scandens caule 
foliato verruculoso ; foliis petiolatis e basi rotundata lineari- 
oblongis acuminatis, petiolo brevi late canaliculato ; racemo 
simplici folio multoties breviore circa 6-floro, rhachi crassa ; 
bracteis late ovatis subacutis; floribus albidis, sepalis et petalis 
ellipticis subobtusis ; labello late saccato basi bigibba columnae 
adnato marginibus reflexis crenulatis roseo-striatis, ore inflexo 
fimbriis crassis instructo ; rostello late elliptico. 
Oban ; n. 776. 
Leaves 17-24 em. long, 4-4:5 cm. broad; petiole 1:5 em. long.
