542 CIX. ACANTHACEX. (C. B. Clarke.) [ Dianthera. 
oid, muticous, subopposite or superposed. Ovary glabrous or nearly so, 
4-ovuled; style minutely hairy below, tip sub-bifid. Capsule clavate, 
4-seeded, base subcylindric solid. Seeds compressed, scabrous verrucose or 
subhispid.—Species 80, chiefly American; about 10 in the tropics of the 
-Old World. 
The character of the genus is here narrowed to the Indian species, which differ 
from the small-flowered Justicias (J. vasculosa, &c.) only by having the lower anther- 
cell absolutely muticous. 
Flowers 3-4 in., sessile or nearly so. 
1. D. leptostachya, Benth. in Gen. Pl. ii. 1114; leaves elliptic or 
oblong narrowed at both ends puberulous on the nerves beneath or glabrate, 
bracts hardly 7, in. linear. Ruellia leptostachya, Wall. Cat. 2411. Lepto-

A herb; stem terete, puberulous. Leaves 44 by 13 in, puncticulate on bot 
surfaces; petiole 3-2 in. Spikes linear, slender, interrupted, mostly collected, in a 
terminal panicle 8-10 in. diam., puberulous ; flowers opposite; pedicels O-To 1D» M 
the lower developed into very small cymes. Calyx-segments 15-3 in., linear-lanceolate, 
puberulous. Corolla scarcely 1 in., nearly glabrous. Capsule } in., clavate, pape 
lous, Seeds glabrous, tubercular-verrucose.—The Philippine plant (Cuming, n. 5 A de 
combined with this species by-Nees, is different, and probably not of this genus (fide 
Bentham). 
2. D. virgata, Benth. in Gen. Pl ii. 1114; leaves elliptic narrowed at 
both ends pubescent on the nerves beneath, bracts ovate or elliptic acute e 
long as the calyx. Justicia virgata, T. Anders. in Journ. Linn. Soc. 1x. 910, 
chiefly.— A dhatoda sp. n. 18, Herb. Ind. Or. H. f. & T.

iii. 105, and Cat. 7177, and in DC. Prodr. xi. 379, from Ava, united with this by ^- 
Anderson, has a very large panicle, cymose flowers and linear bracts, and seems mue 
nearer D. leptostachya. 
3. D. debilis, Clarke; leaves cordate-lanceolate pubescent on the 
nerves beneath, bracts linear or linear-oblong shorter than the calyx. 
KHASIA TERAT, alt. 500 ft.; Shaila, C/arke. 
Resembling D. virgata, but very weak. Leaves 44 by 1$ in., acuminate, mem: 
branous; petiole 1j in. Spikes 1-3 in., linear, often 3 on a terminal peduncle 1-2in. 
bracts jj; in., pubescent; flowers opposite, solitary, distant. Calyx sub-5-partite 5 
segments 4 in., linear, pubescent. Corolla jin, yellowish-white. Anther-cells 
parallel, one very slightly higher than the other. Ovary glabrous; base of style hairy. 
Young capsule as of D. virgata.

acute glabrous, panicles terminal trichotomous, bracts and bracteoles
