floral ones often narrow-lanceolate and much revolute, all in wliorls of 3 or 4, 

 or very rarely the upper ones alternate. Pedicels slender, about | in. long. 

 Flowers S-merous. Sepals ovate-lanceolate. Petals rather narrow. Anthers 

 purple, short and scabrous, al)ruptly contracted into a tube as long as the 

 cells. Ovary glabrous or sligjitly glandular, with 1 ovule in each cell. Cap- 

 sule obovate. Seeds smooth and shining. — T. gracilis, Steetz^ in PL Preiss.

16. T, pubescens, Tarcz. in Bull. Mosc. 1852, ii. 141, Very nearly 

 allied to T, viminea, and perhaps a variety ouly, but the slender rigid branches 

 as well as the upper side of the leaves are often rough with a minute pubes- 

 cence and the long spreading setaj very rare, the leaves, from ovate to lanceo- 

 late, are thicker and almost coriaceous, and often marked on each side w^ith 

 1 or 2 coarse teeth. Pedicels shorter and not so slender. Sepals ovate, 

 obtuse, rarely above 1 line long. Anthers more gradually attenuated into a 

 shorter tube.— r. tenuiramea, Turcz. in Bull Mosc. 1S52, ii. 143. 



"W". Australia. Swan River, Bniminond, 1845, n. 245 ^7/^209. The latter speci- 

 mens distinguished by Turczauiaow under the name of T. temiramea, only differ in their 

 branches rather more slender, 



17. T. pilifera, LindL in Swan Riv, Jpp, 38. Allied to T. dminea, 



but usually smaller and more branched, and readily distinguished by the an- 

 thers. ^ Stems 6 in. to 1 ft, high, slender, and more or less pubescent or hir- 

 sute with stift' hairs, but with^fcw of the long setae except at the nodes, and 

 sometimes almost glabrous. Leaves in whorls of 3 or 4, from ovate to ovate- 

 lanceolate, 2 to 5 lines long, often toothed, glabrous or roughly pubescent on 

 the upper side, with a few hairs on the midrib underneath. Pedicels i to f 

 in. long. Flowers rather smaller than in T. mminea, usually 5-merous, but 

 occasionally 4-mcrous. Sepals ovate or almost lanceolate- Filaments, al- 

 though short, very slender. Anthers pale-coloured, nearly straight, scarcely 

 furrowed, slightly tapering into a very stiort tube. Ovary sliglitly glandular, 

 »iih 1 ovule in each cell. Seeds smooth and shining,— T, Preissiana, Steclz,

18. T. filiformis, l^cnth. Branches in our specimens very long and 

 slender, glabrous or bearing above the internodes a few short spreading pur- 

 ple hairs. Leaves opposite or occasionally in whorls of 3, very rarely 4, nar- 

 row-lanceolate or oblong-linear, ^ to f iuf long, thinner than in most species, 

 flat, obtuse at the base, glabrous. Pedicels veiy slender, more than 1 m. long. 

 Sepals ovate-lanceolate, about 1 line. Petals obovate-oblong, 4 to 5 Imca. 

 Anthers dark puiple, sliort, much curved, very angular, with a straight tube 

 as long as the cells. Ovary glabrous or slightly glaudiUar, with 1 oviUe m 

 each cell.
