150 xcviii. ACANTHACEiE (clarke). [Barle^-ia. 



calyx has much larger leaves with curved primary nerves, otherwise I see little 

 difference. Lindau contrasts B. mucronata with JB. Kirkii (by which he means 

 B. spinulosa) ; this differs a good deal by the sterile bracts being nearly reduced to 

 pinnatifid spines, and the inflorescences having (very many of them) several 

 flowers. 



IG. B. raxnulosa, C. B. Clarke. Stem soft, with spreading and 

 deflexed hairs ; branches many ; nodes very many, short. Leaves 

 J- J in. long, sessile, elliptic, somewhat obovate, obtuse, mucronate, 

 hairy on both faces with small white crispate hairs and scattered long 

 brown needle-like 1-celled hairs; interpetiolar spines J in. long, 

 simple, straight or slightly recurved, more or less hairy. Flowers 

 solitary (rarely 2) ; bracts J in. long, reduced to simple spines, hairy, 

 slightly recurved. Posticous sepal J by ;| in., with many spinous teeth 

 on the margin, hairy ; interior sepals \ in. long, oblong-linear. Ovary 

 glabrous, style n^rly § in. long. Capsule less than \ in. long, 

 4:-seeded.

Resembles much B. huxifolia, Linn., which has a capsule ~ in. long. 



17. B. nyasensis, C. B. Ch/rke. Branches closely hairy with 

 erect hairs. Leaves J by J in., sessile, elliptic, almost acute, mucronate, 

 with many short white hairs and some long 1-celled tawny hairs; 

 interpetiolar spines J in. long, simple, hairy, somewhat recurved. 

 Flowers solitary ; bracts J in. long, simple, hairy, recurved. Posticous 

 sepal |-1 by J-| in., quadrate-ovate, veined, sparsely hairy, with many 

 triangular-mucronate teeth. Corolla exceeding IJ in. in length, blue; 

 tube more than 1 in. long, linear-cylindric, slightly wider upwards.

This hardly differs from B. mysorensis. Roth, which has, however, the corolla 

 usually sraiiller. It is not unlikely that the mature plant of B. nyasensis produces 

 sometimes much larger leaves than those seen. 



18. B. buxifolia, Linn. Sp. Plant, ed. ii. 887. Branches with lax 

 spreading hairs. Leaves J-§ in. long, ovate or obovate, subobtuse, 

 mucronate, nearly sessile ; hairs on both faces scattered, white, short, 

 crispate, also some long, tawny, needle-like, 1-celled ; inter-petiolar 

 spines ^-J in. long, simple, straight, glabrous. Flowers mostly 

 solitary ; bracts J-J in. long, reduced to simple spines. Posticous sepal 

 J by I in. (in the African specimen), broadly oblong, apiculate, veined, 

 hairy, hardly toothed. Corolla-tube (in Indian examples) |-1 in. long, 

 slightly widened upwards, limb purple-blue. Capsule (in African 

 example) f in. long, 4-seeded. — Nees in DC. Prod. xi. 241 ; Wight, Ic.
