150 XCVIII. ACANTHACEE (CLARKE). [ Barleria. 
calyx has much larger leaves with curved primary nerves, otherwise I see little 
difference. Lindau contrasts B. mucronata with B. 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. 
16. B. ramulosa, C. B. Clarke. Stem soft, with spreading and 
deflexed hairs; branches many; nodes very many, short. Leaves 
4-1 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 4 in. long, 
simple, straight or slightly recurved, more or less hairy. Flowers 
solitary (rarely 2); bracts } in. long, reduced to simple spines, hairy, 
slightly recurved. Posticous sepal } by } in., with many spinous teeth 
on the margin, hairy ; interior sepals } in. long, oblong-linear. Ovary 
glabrous, style nearly 3 in. long. Capsule less than 4 in. long; 
4-seeded.

17. B. nyasensis, (’. B. Clarke. Branches closely hairy with 
erect hairs. Leaves } by 4 in., sessile, elliptic, almost acute, mucronate, 
with many short white hairs and some long 1-celled tawny hairs;

Flowers solitary; bracts 4 in. long, simple, hairy, recurved. Posticous

triangular-mucronate teeth. Corolla exceeding 1} 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 smaller. 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 4-3 in. long, ovate or obovate, subobtuse,
