In Engl. Jahrb. xxviii. 41, Hallier includes nos. 6175 and 6176 

 under I. kentrocarpa Hochst., a species based on an Abyssinian 

 specimen, but localities for which are cited both in East and West 

 Tropical Africa. No. 6174, which Hallier {I.e. 87) excludes with a 

 query from I. ochracea, agrees with these two numbers, having the 

 blunter calyx and shorter corolla. The three closely resemble 

 I. kentrocarpa Hochst., but our specimen of the number (1420), on 

 which the species depends, is but a fragment, and hardly allows a 

 definite opinion. Dr. Hallier may have seen better material.

Described from a small specimen consisting of a somewhat 

 sparsely leaved shoot, 13 cm. long by 1*5 mm. broad, springing 

 from a short stouter woody axis, 2*5 cm. long, including two seasons' 

 growth. Leaves tapering gradually from the rounded base to the 

 shortly cuspidate apex, the largest 23 mm. long by 4 mm. broad at 

 the base ; petioles 4 mm. or less. Peduncles 6-7 mm. long, bracteoles 

 2 mm. long, 3 mm. below the calyx. Outer sepals 6-8 mm. long 

 by about 3 mm. broad, the inner reaching 12 mm. long and narrow- 

 ing to 2-5 mm. Corolla apparently about 3 cm. long, with a short 

 tube about -5 cm. in diameter,
