% 5,^ G. micrantha, Benth. Smaller and more branclied than the otlier 



species, but equally toinentose. Leaves on very short pi-^tioles, oblong-linear 

 or almost lanceolate, obtuse, mostly under \ in. and rarely 1 in. lonji:, the 

 margins much revolute. Stipules obliquely ovale-cordate, usually very small, 

 and sometimes wanting. Kaccmes 3- to 6-fiowered. Bracteoles linear-iili- 

 form. Calyx about 3 lines long-, very broad and angular, the sepals united 

 much above the middle, with 3 or 5 ])rominent ribs to each. Filaments very 

 short, alternating with small stamlnodia ; anthers very truncate and usually 

 tipped with a tuft of short hairs. Ovary tomentose, 5-ccllcd; style densely 

 covered with stellate hairs from below the middle to the top. — Sarotes mi-

18. LASIOPETALUM, Sm. 



(Coretlirostylis, Endl.) 



Calyx 5-lobed nearly to the base, not much enlarged after flowering, with- 

 out prominent ribs, the sepals obscurely several-veined at the base. Petals 

 small and scale-like, or rarely none. Stamens 5, opposite the petals, sligldly 

 ^ounected at the base or free, without intervening staminodia; anthers open- 

 ing in terminal or inwardly obliciue pores or short slits, which rarely extend 

 down the sides. Ovary 3-cellcd, or rarely 4- or 5-ccllcd, with 2 or very 

 rarely more ovules in each cell ; style simple. Capsule shorter than the 

 calyx, opening loeulicidally. Seeds usually solitary in each cell, erect, stro- 

 phiolate, albnminous ; embryo straight, with flat cotyledons. — Shrubs, more 

 or less tomentose or p\d)csccut with stellate hairs. Leaves entire or rarely 

 lobcd, often coriaceous and glabrous on the upper side, in one species nearly 

 all opposite, and in some others occasionally so. Stipules none. Flowers 

 in small drooping cymes contracted into heads, or in looser-branched cymes, 

 or rarely in simple racemes. Bracteoles 3 or fewer, in some species very 

 small. 



The genus is entirelv Australian. It differs from Thomasia chiefly in the calyx and 

 generally in habit. The want of stipules is constant in Lasiopetahm , but occurs also in 

 the section Ilhyachostemon of Thomasia, to which some Laswj)eMa of the section Core-, 

 tkrostylh bear much affinity. They are, however, readily kjiovvu Ly the peculiar hairs of 

 the style in that group, which never occur in Thomada, 



A. Style glah-ous, 



bracteoles lon<rer than the cnlyic, forming an involucre round the 

 soft woolly flower-heads. Leaves cordate-ovate, whitc-tomcntose
