1. T. decandra (ten-stamened), Linn.; DC. Prod. iii. 852; Bentli. FI. 
Austr. iii. 329. Procumbent and glabrous, said to be annual, but the specimens 
sometimes show a hard woody base ; branches dichotomous, rarely attaining 1ft. 
Leaves from broadly obovate to oblong, f to lfin. long, narrowed into a rather 
long petiole. Flowers several together in a cluster, not exceeding the petiole, 
although sometimes very shortly pedunculate. Bracts and bracteoles small and 
scarious. Calyx about 1 line long when in flower, somewhat enlarged when in 
fruit, the lobes longer than the tube, scarious on the margin and mucronate close 
to the end. Stamens 10 to 12 or sometimes a few more. Ovary ovoid, truncate, 
with a few prominent tubercles, 2-celled ; ovules 2 in each cell, collaterally 
ascending from a basal placenta, shortly adnate to the dissepiment ; styles 2. 
Capsule about 2 lines long, the seeds superposed in each cell, the upper one 
ascending, the lower one pendulous ; when ripe the upper portion separating into 
2 cocci, opening on the inner face, the lower portion circumsciss below the 
insertion of the seeds. Seeds black, rugose. — Wight, Ic. t. 296 ; F. v. M.

| to fin. long, 2 to 3 lines thick, giaucescent, the petioles membranously dilated 
at the base. Calyx lobes 5, not 1 line long. Anthers dorsifixed. Style 
setaceous, 1 line long. Stigma minute. Capsule ovate, many seeded, cir- 
cumscissile, operculum lit line long, matured seeds few, black, pyriform-renate,

3. T. crystallina (with transparent vesicles), Valtl, DC. Prod. iii. 352; 
Benth. FI. Austr. iii. 330. Glabrous or slightly pubescent or covered with little 
transparent vesicles, prostrate or diffuse, the wiry dichotomous stems sometimes 
extending to 1 or 2ft., sometimes short and compact. Leaves from oval-oblong 
to linear. Flowers small, in axillary cymes or clusters, much shorter than the 
leaves. Calyx about If line long, the lobes narrow, obtuse, spreading, rather 
longer than the tube. Stamens 5. Ovary of 1 carpel, truncate, with 2 erect 
ovules ; style excentrical. Capsule short and broad, the top concave, forming a 
short broad cup round the style. Seeds 2, granular, flat, obliquely superposed. —
