Platytheca (Greek, broad anther-cells). Treman- draceae. Small shrub, somewhat heath-like, suitable for greenhouse culture. Leaves whorled: fls. 5-merous, numerous, borne toward the end of the branches, light purple, about 1 in. across, center marked with a red star; stamens distinctly in 2 rows, anthers continuous on the same plane as the filament, with 4 parallel cells; disk inconspicuous: caps, loculicidally dehiscent, 4-valved. One species. Austral.—Platytheca belongs to a small beautiful and distinct family of Australian shrubs, composed of 3 genera, of which Tetratheca is the dominant type. The Tremandra family resembles the Poly gala family in the structure of the caps., but differs in the regularity and estivation of the fl.; it resembles the Pittosporaceae in having a very small embryo immersed in copious albumen, and particularly the genus Cheiranthera in having anthers which open by a pore at the top. The three genera of Tremandraceae are distinguished from one another by the anthers; Tremandra differs from the other two in having the anthers jointed with the filaments; in Platytheca the anthers have 4 cells all in the same plane; in Tetratheca the anthers are 2-celled or 4-celled, with 2 cells in front of the 2 others.
