Roxhurghia. octandria monogynia. 235 



J?oof perennial, compounded of many, smooth, cylindric, 

 fleshy tubers, of from six to twelve inches lon^, and from 

 three to five in circumference about the middle; they 

 taper equally towards each end. Stems perennial, or 

 more, twining, smooth, running over trees, &c. Branches 

 like the stem, round, smooth, and slender. Leaves some- 

 times alternate, sometimes opposite, petioled, nearly de- 

 pending, cordate, fine-pointed, entire, smooth, shining, in 

 substance soft and delicate, generally eleven-nerved, 

 with beautiful very fine, transverse, veins running be- 

 tween the nerves ; from four to six inches long, and from 

 three to four broad. Petioles slightly channelled, 

 smooth ; one and a half and two inches long. Peduncles 

 axillary, single, erect, the length of the petioles, general- 

 ly two-flowered. Pedicels clubbed, short. Bractes one, 

 lanceolate, at the base of the pedicells. F/ott;ers large, and 

 beautiful, but foetid. Calyx four-leaved ; leaflets lanceo- 

 late, membranaceous, striated, coloured, revolute, placed 

 immediately below the petals. Corol ; petals four, near- 

 ly erect, lanceolate, the lower half is rather broader than 

 the upper, and along its inside runs a deep, sharp, 

 slightly waved keel, which forms on each side of it, a 

 deep groove, or hollow; these four keels converge, and in 

 some measure adhere together, which brings the side of 

 the petals close so as to resemble a tube ; the upper part 

 of the petals is narrow, first bending out a little, then 

 converging at their points. Nectary com])osed of four, lan- 

 ceolate, yellow bodies, each sitting sessile on the apex 

 of the keel of the petals, converging into one conical 

 dome. Filaments none. Anthers eight, linear, lodged 

 in the grooves formed by the keel of the petals, adhering 

 their whole length, but their chief insertion is near the 

 base. Germ superior, cordate, compressed, one-celled ; 

 ovula many, attached to the bottom of the cell, cordate. 

 Style none. Stigma ]^o'mted. Capsule ovAte, compress- 

 ed, one-celled, two-valved, opening from the apex ; it is
