3. THOTTEA TRICORNIS, Maingay ex Hook. f. in Fl. Br. Ind. V. 
74 (1886). A shrub, reaching 1—2 m. in height; branches stout, 
pale brown, puberulous, swollen and jointed at the nodes, internodes 
channelled. Leaves coriaceo-chartaceous, distichous ; elliptic-oblong 
or -obovate, or -oblanceolate, acute or acuminate at apex, attenuate and 
rounded at base, entire ; upper surface glabrous, lower hoary-pubes- 
cent ; 20—30 cm. long, 7—13 cm. broad ; 5-ribbed from the base, the 
midrib stout, prominent, the inner pair slender reaching to about two- 
thirds up and then looped, the outer pair close to the margin, small, 
looped ; main nerves from the midrib 6—8 pairs, curved upwards and 
joined by many prominent curved transverse nervules and a conspicuous 
reticulation, all ribs and nerves much raised beneath ; petiole stout, 
_ twisted, 6—10 mm. long. Cymes paniculate, 3—5 cm. long, densely 
tawny-puberulous ; bracts linear or lanceolate, small, lower ones leafy - 
buds depressed globose, 8 mm. in diam., the top with 3 raised points. 
Perianth urceolate, only slightly open at the mouth in 3 short lobes, 
erey and red, leathery. Stamens in 2 rows, the outer with 12—14, 
the inner with 6—8 ; filaments about 1 mm. long; anthers as long, 
curved. Ovary slender, tawny-puberulous ; style column thick below, 
dividing above in 4 to 6 subulate stigmatic arms 1°55 mm. long. Cap- 
sule 15 to 20 cm. long, quadrangular, tawny-pubescent, 4—5 mm. in 
diam., not torulose. Seeds oblong-trigonous, shortly tubercled, 4—5

3. ARISTOLOCHIA, Linn. 
Shrubs or perennial herbs, prostrate or climbing; rhizome often 
tuberous. Leaves alternate, generally petioled, entire or lobed, 
often with a stipule-like leaf of an undeveloped bud in the axil, 
otherwise exstipular. lowers solitary or fasciculate or in the leaf- 
axils, bracts at the bases of the flowers often rather large. Perianth 
very variable in shape, size and colour ; usually the tube inflated below, 
then contracted in a cylindrical neck, then again expanded in a 
2-lipped oblique limb, tube usually villous within. Stamens 6 (rarely 
less or more) adnate to and around the style-column with which the 
filaments and connectives are merged; cells 2, distinct, extrorse. 
Ovary inferior, 6-celled (rarely less or more); placentas parietal or 
intruded or connivent and connate in the axis; ovules very many, 
1—2-seriate, anatropous, in vertical rows ; style column thick, divided
