288 Eivart, White and Wood : 



Angianthus lanigkrus, Ewart and White, n. sp. (Compositae). 

 (PI. JJ., Figs. 1-5). 



Wooroloo, Max Kocli, 1907, No. 1873. 



Herbs 4-8 inches in height, stems freely branching, especially 

 towards the top, glabrous when old — when young covered with 

 dense white woolly hairs. Leaves .5-1 inch long, sessile, linear, 

 pointed, but expanded and slightly ensheathing at the base, 

 more or less covered with white hairs, alternate. Inflorescence 

 solitary, axillary, 2-3 lines in diameter, ovoid-convex, surrounded 

 bv an involucre of foliose, lanceolar, rather pointed bracts, which 

 are covered with white woolly hairs, and have very small mem- 

 branous margins, and are about "2 lines in length, being longer 

 than the florets. Thei-e is an inner circle of flat, membranous 

 bracts, which are obtuse, and provided at the top with a tuft of 

 hairs, and have a very small foliose portion in the centre. 



Partial heads 1-flowered suri'ounded by 3 membranous bracts 

 all of which are lanceolar, obtuse at the top, where also there 

 is a tuft of hairs, and all are more or less concave. The pappus 

 is absent, and the florets are pale yellow in colour, and 5-merous. 

 and not thickened at the base except as the fruit begins to ripen, 

 when the base becomes very slightly thickened. Achenes slender, 

 pale in colour, about one-third the length of the floret, some- 

 what tapering at the base. 



The species seems to be nearest to Angianthus strictus, to 

 which it was referred as a variety in the Contributions to the 

 Flora of Australia, No. 12 (Proc. Roy. Soc. of Victoria 22, 1909, 

 p. 92). It differs in the following respects: — 



(1.) The bracts surrounding the compound head are broader 

 and much less pointed. 



(2.) The whole inflorescence is much more woolly. 



(3.) The number of bracts surrounding each partial head is 

 3 (rarely 4), instead of 2. 



It lias been refei'red to A. Preissianus by another botanist, but 

 differs from that species in the following respects: — 



(1.) The plant is much larger and more vigorous, and branches 

 more freely. 



(2.) Tlie bracts of the partial heads are more concave, and 

 each has a fringe of hairs on the upper margin.
