Ruellia anisophylla, Wallich, MSS. 
Perennial, with a zig-zag, branched, green, acutely quadrangular, glabrous 
stem, about a foot high in our plant. Leaves 3-4> inches long, very shortly 
petiolate, distichous, oblong, acute at the base, very much attenuated at 
the extremity, serrated at the margin, glabrous, above dark green, with 
prominent veins, below paler, the veins sunk in the substance of the leaf: 
one of each pair of opposite leaves is constantly abortive, and seems to be 
little more than a lanceolate bractea at the base of an abortive flower-stalk. 
Fertile flower-stalks from'the axil of the fully developed leaf, and leaning 
to the underside, much shorter than the leaves, quadrangular, with one 
or two (when two, the lower one sessile) small heads of flowers, of 
which 2 or 3 are expanded at a time. Cali/x small, deeply 5-fid, pu- 
bescent, the segments narrow : each is subtended by 3 bracteee, two la- 
teral, and one, the larger one, in front; these are lanceolate. Corolla 
large, handsome, pubescent externally, and veined, narrow, and yellow 
at the base, above enlarged, pale bluish-purple, showy, the mouth 
spreading, 5-lobed, lobes somewhat irregular, crenate at the margin. 
Stamejis 4, didynamous, aU perfect. Filaments white, thick, adnate with 
the corolla for almost their whole length, pubescent at the base, the ex- 
tremity curved and swollen, bearing a 2-lobed anther ; each lobe acute, 
somewhat spreading, opening transversely, yellowish- white. Pistil: 
Germen oblong, small. Sti/le long, slender, filiform, slightly thickened 
upwards. Stigma acute.
