Psathura. pentandria monogynia. 531 



Trunk straight, covered with smooth, ash- coloured bark. 

 Branches numerous, spreading, so as to form a large ovate 

 head. Leaves opposite, petioled, ovate, and ovate cordate, 

 downy; veins simple and parallel ; length from two to eight 

 or ten inches. The floral pair or two Ionger-petioled, somewhat 

 scarious, smoother, and more permanent than the others. Pe- 

 tioles round, villous, about a third of the length of their leaves. 

 Stipules large, oblong, downy, and fringed with coloured 

 glands round the margin. Thyrses terminal, and from the ex- 

 terior axills, from oblong to sub-cylimlric, very dense, short- 

 peduncled, drooping. Flowers small, greenish-yellow, very 

 fragrant, collected in numerous small fascicles, on very short, 

 common peduncles. Bractes linear-lanceolate, one to each 

 fascicle, smaller ones to the proper pedicels. Calyx about 

 five-toothed, villous. Corol ; tube cylindrie, more than twice 

 the length of die calyx. Border five-parted, pitcher-shaped, 

 length of the tube. Filaments short, inserted into the mouth 

 of the tube. Jlnthers sagittate, hid in the pitchered border. 

 Germ two-celled. Style twice the length of the corol. Stig- 

 ma globular. Capsule inferior, oblong, warty ; size of a filbert, 

 two-celled, two-valved, opening from the apex ; partition con- 

 trary, and in this respect only does it differ from Cinchona. 

 Is this a sufficient reason to remove it from that family ? In 

 C. excelsa, the partition is also contrary, receptacle placed lon- 

 gitudinally along the suture of the partition. Seeds several 

 in each cell, imbricated upwards, surrounded with a broad, 

 brown, reticulated, membranaceous wing, which is cloven be- 

 low up the umbilicus, at the base of the seed. Perisperm thin, 

 white, and fleshy. Embryo erect, nearly as long- as the peris- 

 perm. Cotyledons cordate. Radicle oval, inferior.

Calyx superior, from four to six-toothed. Corol one-petal- 

 led ; tube short, and hairy within ; border from four to six-
