XX. Justicia.—Corolla-tube not much longer than the limb, Seeds usually 4 to 
the capsule, rough or tubercular. 
XXI. Monechma.—Corolla-tube not much longer than the limb. Seeds 2 to the 
capsule, smooth, usually shining. 
XXII. Siphonoglossa.—Corolla-tube slender, much longer than the limb. 
tt One anther-cell slightly below the other, hardly tailed at the base (or very 
shortly tailed in Adhatoda). See also 20. Justicia. 
XXIII, Adhatoda.— Inflorescence congested ; bracts conspicuous. Corolla-tube 
broad. Capsule 1-2-seeded. 
XXIV. Rhinacanthus.—Inflorescence diffuse; bracts inconspicuous. Corolla-tube 
long linear; posticous lip small. Capsule 4-seeded.

XXVI. Isoglossa.—Pollen globose, flattened, with a stopple in the centre of 
each face. 
*** HyporsTex. Placenta not rising elastically from the base of the capsule. 
Spikelet usually of 1 flower with an imperfect second flower, appearing 
included by the two bracts corresponding to the two flowers or overtopped by 
the 2 bracts when they ure narrow. 
XXVII. Peristrophe.—Anthers 2-celled, one cell much above the other. 
XXVIII. Hypoestes.— Anthers 1-celled, 
**** SoLutx. Placente rising elastically from the base of the capsule with the 
ripe seeds, 
XXIX. Macrorungia.—Shrubs. Caly# divided about half-way down. Corolla 
red; lips 1 in. long. 
XXX. Dicliptera.—Herbs. Calyw divided to the base. Corolla pink. 
I. THUNBERGIA, Linn. f. 
Bracteoles 2, large, elliptic or ovate. Calyx much shorter than 
the bracteoles, either subtruneate or of 10-14 small linear teeth. 
Corolla: tube oblique, more or less widened upwards; lobes 5, 
rounded, spreading, contorted in the bud. Stamens 4, didynamous; 
connective often produced at the top as a short horn ; anthers nearly 
similar, 2-celled, oblong, often spurred at the base and with beaded 
hairs, Pollen globose, obscurely banded, smooth or most minutely 
tubereled. Ovary ovoid, acute; style funnel-shaped, or of two lobes 
one below the other; ovules in each cell 2. Capsule globose, 
abruptly rostrate, loculicidally dehiscent, Seeds in each cell 2, near 
the base, subhemispheric or flattened; hilum central on the ventral 
face, attached directly to the placenta without retinacula.
