106 SOUTH NIGERIAN PLANTS 
bases, the edge of which is scarious and pale brown. Leaves dark 
green to 17 cm. long by "5 em. broad. Racemes about 1 cm. long; 
bracts 4-5 mm. long. Flowers white spotted on the outside (backs of 
sepals, venter of lip, spur and ovary) with dark brown scale-like hairs. 
Dorsal sepal 2:7 mm. long, lateral sepals 89:5 mm. long by 1:7 mm. 
Petals of much thinner texture than sepals, 2°75 mm. long; lip 4 mm. 
long from the base of the spur, white with a bright green patch on the 
tip of the side lobes, spur transparent green, 2:5 mm. long. Column 
1°6 m. long; caudicle 1:5 mm. long, gland 1°25 mm. 
Near A. clandestinum Lindl., which it resembles in the general 
structure of its flowers; the flowers are, however, only about half the 
of those of A. clandestinum, which, moreover, has ensiform 
eaves, 
Angraecum Straussii Schlechter. Oban; n. 940. Previously 
collected by A. Strauss near Moliwe in the Cameroons. The 
leaves in the Nigerian plants are larger than in the type, reaching 
14 cm. long by ‘7 cm. broad. A sketch by Mrs. Talbot shows 
them as much as 1*2 cm. broad. The colours of the flowers, as 
noted by Mrs. Talbot, are: sepals and petals white, lip cream 
with bright green marks at the base of the disc, pedicel and. 
ovary pale brown with minute spots of darker brown. 
Angraeeum angustipetalum Rendle sp. nov. Planta caule 
compresso vaginis foliorum persistentibus vestito ; foliis lanceolatis 
vel oblongo-lanceolatis apice bilobo lobo altero longissimo acumi- 
nato; pedunculis tenuibus unifloris (?) quoque vaginam folii . 
penetrante et basi bractea brevi tubuliforme instructo ; floribus 
longius pedicellatis, pedicello filiforme ; sepalis lineari-acuminatis 
5-nerviis; petalis e basi latiore angustissime lineari-acuminatis 
(siccis filiformibus) ; labello ovato acuto; calcare ab ore lato 
gradatim angustato medio filiforme deinde gradatim inflato ;

Oban ; n. 890. ; 
The specimen consists of several detached shoots, the longest 
14 em. Internodes about 1:29 cm. long, the compressed almost 
keeled leaf-sheaths to *6 em. broad; leaves 7:5-9 cm. long, 1:2-2:2 
em. broad. Peduncles 1-1:8 cm. long; pedicels with ovary about 
2 cm. Sepal about 2 cm. long by 2 mm. broad, the dorsal slightly: 
exceeding the lateral; petals as long as the lateral sepals, less than 
"5 mm. broad at the middle; lip 1-8 cm. long by 7 mm. broad; spur 
2 em. long, 2 mm. in diameter below the mouth; 1-1:25 mm. at the 
inflated apex. 
A distinet species allied to and recalling in habit Angraecum 
astroarche Ridl. from the Island of St. Thomas, but with much 
smaller flowers, resembling more in size those of A. verrucosum 
Rendle from Mt. Milanji, Nyassaland. The slender almost thread- 
like petals are very characteristic. Also closely allied to Mystacidium 
zn Rolfe from Old Calabar, which, however, has a differently 
shaped lip. j : ir ps P
