25. T, pygmaea, Benlh. Not much branched and only 3 or 4 in. high, 

 out woody, the young shoots and under side of the leaves covered with a 

 mimite scaly tomentum. Leaves shortly petiolate, orbicular-cordate, 3 to 4 

 hues diameter, entire, coriaceous and glabrous above when full-grown. Sti- 

 pules none. Flowers large, solitary or 2 together, on peduncles longer than 

 the leaves. Bracteolcs very small, close to the calyx. Calyx very angular, 

 spnnkled with stellate haii's more or less united into scales, deeply divided 

 into broadly ovate-cordate, acute segments, attaining fully 5 lines, thin and 

 petal-like, with the midribs prominent inside. Petals none. Filaments rather 

 l^ng; anthers very obtuse. Ovary covered with scale-like papilla?, 5-celled, 

 with 2 ovules in each cell. Style glabrous, prominently 5-ang!ed, almost 

 5-winged to near the summit ; stiguias at length separating, — Asterochiton

NotwitLstaudiiig the curious style, this plant is too closely allied to T, sielliyem to lie 

 sepaniteJ from it ^eiierically. I liad formerly referred iheT^i both to Lasiopetalum, but tiicy 

 Iiave the calyx of Thomada, a character which, after a detailed review of all the species, appeal s 

 to be the best for distiuguishing naturnlly the two genera.

(Sarotes, LindL) 



Calyx 5-lobed, enlarged and membranous after flowering, with raised ribs, 

 3 or 5 to each sepal. Piitals 5, small and scale-like. Stamens 5, opposite 

 the petals, slightly connected at the base or free ; staminodia none or rarely 

 1 to 5, vei-y small, alternating with the stamens. Anthers opening at the top 

 towards the inside in short slits, which at length extend more or less down 

 the side. Ovary 5-celled, with 2 to 5 ovules in each cell. Style simple. 

 Capsule shorter thnn the calyx, opening loculicidally in 5 valves. Seeds 

 ^sudly strophiolate, albuminous; ehihiyo straight, with flat cotyledons.— 

 Shrubs, more or less tomentose with stellate hairs. Leaves narrow, entire, 

 with revolutc margins. Stipules leafy, either similar to the leaves or shoit 

 and obli(pie. Kacemes simple, leaf-opposed. Bracts small and deciduous. 

 -Bracteoles small, and not so close to the calyx as in most Lasioj)etalea. 



The genus is confhied to Australia. It ditTers from Thomasia chiefly in the calyx. The 

 leaves aud stipules of those species where they are similar are soinetimes described as verti- 

 ciUate leaves.

 otipules like the leaves and scarcely smaller. ^. .
