ADDITIONS TO TASMANIAN FLORA. 

 By. L. Rodway. 



Before the year closes I am anxious to place on record a 

 brief description of three interesting plants. Of these two 

 are new species, the other doubtless introduced. 



Bauuticulus setaceus. ns — A small glabrous, tufted 

 perennial with numerous, fairly stout, long, fibrous roots. 

 Leaves numerous setaceous, but slightly flattened, simple or 

 with one pair of filiform simple lobes towards the apex, 

 1 — 3 in. long, apices sometimes tipped with glands, base 

 rather broad sheathing. Flower solitary on a slender 

 peduncle, always shorter than the leaves, sometimes very 

 short. Flower rather small, yellow, sepals broadly ovate, 

 erect, pointed, 1^ lines long. Petals scarcely exceeding the 

 sepals, usually 5 — 6, very narrow, oblong, blunt, gland about 

 the middle. Stamens very vai'iable in number in proportion 

 to robustness of habit. Achenes not numerous, somewhat 

 flattened, smooth, style slightly curved ; ripe achenes more 

 swollen with a sharply recurved style ; receptacle short, 

 conical, beset with bristles. Not at all or sparsely stoloniferous. 



In mud and under water in and about pools on the 

 Ironstone Range, alt. 3,000ft. 



The plant flowers freely under water, and does not when 

 permanently submerged depart in any manner from the 

 sub-aerial form. 



I have described this plant as a new species only after 

 mature consideration. Its relationshij) to M. rivularis, Banks. 

 et Sol., is undoubted, but if it is taken as an extreme variety 

 of that species where are we to draw the line? This plant is 

 very close to R. millanl, F. V. M. and R. robertsoni, B., and 

 if these are included with R. rivularis we shall also have to 

 take in many New Zealand and S. American plants. Even 

 with this extensive clubbing the species would be still ill- 

 defined, and the mass of varieties would be unworkable. 



Pseudanthus tasmanicus. ns — A prostrate, wiry, much- 

 branclied spreading undershrub, 1 — 2 ft. long. Dioecious. 

 Young parts tuberculato-hispid. Leaves alternate, broadly 

 ovate to orbicular, sometimes with a small blunt point, other 

 times slightly emargiuate, 1 — 2 lines long on a slender petiole 

 of similar length. Stipules scarious, sheathing blunt, often 

 abruptly truncate \ — I line long. Male flowers solitary in 

 the upper axils, pale green. Perianth lobes equal or nearly
