Adhatoda. | XCVUI. ACANTHACEH (CLARKE). 221 
45, ADHATODA, Nees; Benth. et Hook. f. Gen. Pl. ii. 1112. 
Calyx subequally 5-tid to the base ; lobes clearly imbricate. Corolla 
large, 2-lipped; tube nearly as long as the lips, inflated in the upper 
half; anticous lip ovate, 3-lobed ; posticous nearly entire. Stamens 2, 
glabrous ; anther-cells oblong, parallel, at nearly equal height, rounded, 
acute or shortly tailed at the base; poilen ellipsoid, the longitudinal 
smooth depressions with rows of patches, hardly of tubercles. Ovary 
shaggy; ovules 2 in each cell; style very shortly and equally bilobed. 
Capsule oblong-clavate, on a short solid stalk, 4—2-seeded ; seeds rugose, 
sometimes obscurely so, not shining; placente not rising elastically.— 
Shrubs. Leaves large, elliptic, entire, much attenuate at either end, 
Spikes terminal, peduncled, forming a thyrsus or solitary; bracts 
ovate or linear-oblong ; bracteoles 2, about as long as the calyx. 
Species 8, in the tropical parts of Asia, Africa and America. 
Adhatoda was described as a genus by Nees in Wall. Pl. As, Rar. iii. (1832) 102 ; 
and the name thus has priority over Duvernoia, Drége, first described by Nees in DC. 
Prod. xi. (1847) 322. But, if the bare printing of the name Duvernoia by Droge in 
1837 be maintained to constitute priority of publication, it is not advisable to adopt 
the generic name Duvernoia for the subjoined species of Adhatoda, because Duvernoia, 
by reason of its campanulate calyx with subvalvate triangular lobes, would be by some 
(who sink Adhatoda in Justicia) kept up as a monotypic genus. 
Adhatoda, though not well separable from Justicia by any one character, is here 
understood (as by Bentham) to comprise certain sbrubs 4-12 ft. high, with large 
leaves and shaggy ovaries, in which the lower of the 2 anther-cells is not remote nor 
very long-tailed (as it is in Justicia).

Shrub. Leaves 6 by 2} in., narrowed at either end, obtuse, glabrous ; 
petiole 1-3 in. long. Spikes 3-7 by 1 in., several peduncled, often 
forming a terminal thyrsus, strobilate; bract % by $ in, minutely 
pubescent, with a prominent scarious margin ; bracteoles }_1 in. long, 
ovate. Sepals 5, nearly separate, subsimilar, } in. long, oblong-lanceolate, 
pubescent. Corolla 1 in. in total length, yellowish, purple-spotted, lips 
% in. long. One anther-cell slightly below the other, mucronate at the 
base ; pollen ellipsoid, with two stopples, and rows of spots on the 
longitudinal smooth bands. Ovary and style-base shaggy. Capsule 3-1 
in. long, pubescent, usually 4-seeded, lower 4 part a cylindric stalk ; 
placente not rising elastically: seeds glabrous, rugose.—A. Rich. Tent.
