168 XCVIII, ACANTHACEE (CLARKE). [Barleria. 
Mozamb. Dist. German East Africa: Usambara; Mascheua, Holst, 3515! 
8736! Kwa Mshuza, Holst, 8935! Usagara, Stuhlmann, 289 ! 
The description of B, submollis, Lindau, “leaves subcordate, corolla-tube 1 in., 
lobes 4 in.,” appears taken from Volkens, 314; and cannot apply to Holst, 8736 
(whence the above description of B. Stuhlmanni is drawn), though this Usambara 
plant is the one repeatedly named by Lindau as submollis. These species of Barleria 
are very close together, and the number of species hereafter admitted may be greater 
than that enumerated here. 
74. B. micrantha, (. B. Clarke. Young parts tawny villous. 
Leaves up to 23 by 1 in., ovate-elliptic, subacute at either end, when 
mature with few scattered small hairs and conspicuous cystoliths ; 
petiole 0-1 in. long. Inflorescence in 3—1-flowered dense racemes, 
scattered in remote axils. Posticous sepal 4 by 4 in., rhomboid, 
definitely toothed ; anticous calyx-segment similar, rather smaller, tip 
with 2 acute triangular lobes. Corolla in total length hardly ; m., 
trumpet-shaped, purple-blue when dried. Stamens and pistil of the 
genus. 
Wile Land. East side of Lake Albert Edward, Scott-Elliot ! 
In the larger, sparsely hairy leaves, this species resembles B. Grantit and 
B, ruellioides ; but the corolla is far too small to arrange it under either of 
these. 
75. B. usambarica, Lindau in Engl. Jahrb. xx. 21. Villovs, 
6-10 in. long. Leaves } by } in., tip triangular, base rounded ; petiole 
0-1; in. long. Inflorescence in 2-1-flowered scattered racemes ; bracts 
zis in. long, linear-lanceolate. Posticous sepal } in. long and broad, 
acute, subentire ; anticous calyx-segment } in. long, obovate, 2-nerved, 
minutely 2-toothed. Corolla in total length ? in.; tube in the upper 
half funnel-shaped. Ovary glabrous; style with scattered hairs in the 
lower part. Capsule less than } in. long, compressed ellipsoid, 2-seeded. 
—Lindau in Engl. Pf. Ost-Afr. C. 369. 
Mozamb. Dist. German East Africa: Usambara, Duga, Holst, 3165! 
Much smaller than any other species. 
76. B. rotundisepala, Rendle in Journ. Bot. 1897, 376. Small, 
densely strigose shrub. Leaves up to 1} by 3 in., obtuse, grey-strigose 
on both faces, narrowed at the base ; petiole Lin. long. Flowers solitary; 
shortly pedicelled above 2 reduced leaves. Posticous sepal orbicular, 
nearly } in. long, densely strigose without; anticous calyx-segment 
similar but rather smaller; two inner sepals } in. long, lanceolate. 
Corolla } in. Jong, or rather more. Style-base and ovary-top shortly 
hairy. 
Nile Land. British Somaliland: Waggar Mountains, Mrs, Lort Phillips ! 
Rendle thinks this species may belong to the subgenus Somalia. In tbe absence 
of fruit, this can hardly be settled; I guess its affinity to be with B. usambarica:
