106 SOUTH NIGERIAN PLANTS 



bases, the edge of which is scarious and pale brown. Leaves dark 

 green to 17 cm. long by "5 cm. broad. Racemes about 1 cm. long; 

 hracts 4-5 mm. long. Flowers white spotted oa the outside (backs of 

 sepals, venter of lip, spur and ovary) with dark brown scale-like hairs. 

 Dorsal sejyal 2' 7 mm. long, lateral sepals 3-5 mm. long by 1-7 mm. 

 Petals of much thinner texture than sepals, 2 ■ 75 nun. 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. clanclcstinum Lindl., which it resembles in the general 

 structure of its flowers ; the flowers are, however, only about half the 

 size of those of A. clandestinum, which, moreover, has ensiforni 

 leaves. 



Angraeeum 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. 



Ang-paeeum angustipetalum Rendle sp. nov. Planta caule 

 compresso vaginis foliorum persistentibus vestito ; foliis lanceolatis 

 vel oblongo-lanceolatis apice bilobo lobo altero longissimo acumi- 

 nato ; peduncidis tenuibus unifloris (?) quoque vaginam folii 

 penetrante et basi bractea brevi tubuliforme instructo ; ft or thus 

 longius pedicellatis, pedicello filiforme ; scpalis lineari-acuminatis 

 5-nerviis ; petalis e basi latiore angustissime lineari-acuminatis 

 (siccis filiformibus) ; lahello ovato acuto ; calcare ab ore lato 

 gradatim angustato medio filiforme deinde gradatim inflato ; 

 columna crassa. (PI. 14, figs. 10-12.) 



Oban ; n. 890. 



The specimen consists of several detached shoots, the longest 

 14 cm. Internodes about 1 • 2 cm. long, the compressed almost 

 keeled leaf-sheaths to "6 cm. broad; leaves 7 "5-9 cm. long, 1*2-2 '2 

 cm. broad. Peduncles 1-1 "3 cm. long ; p^cZ/ceZs witl: 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 cm. long, 2 mm. in diameter below the mouth ; 1-1 "25 mm. at the 

 inflated apex. 



A distinct species allied to and recalling in habit Angracum 

 astroarche Eidl. 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 vei'y characteristic. Also closelj' allied to Mysiacidium 

 aiigustum Eolfe from Old Calabar, which, however, has a difl'erently 

 shaped lip.
