(Benth.), except that the phyllodia are slightly obtuse. — It apparently 
comes nearest to Acacia striatula, but differs in the following characters. 
— 1. The branches are not minutely pubescent. — 2. The phyllodia are 
not tapering. — 3. The flowers are not numerous on the heads. — 
4. The midribs are not prominent in the petals. — West Australia,

51. Angianthus lanigerus Ewart and White, l. c., p. 288, pl. LI, 
fig. 1—5. (Compositae.) — 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 0,5—1 inch long, ses- 
sile, 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 by an invo- 
lucre of foliose, lanceolar, rather pointed bracts, which are covered 
with white woolly hairs, and have very small membranous margins, 
and are about 2 lines in length, being longer than the florets. There 
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 surrounded 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, somewhat 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 has been referred to A. Preissi- 
anus 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. The bracts of the partial heads are more 
concave, and each has a fringe of hairs on the upper margin. — 3. The 
florets have not the thickened base of A. Preissianus. — 4. The partial 
heads are always 1-flowered. — 5. There is no pappus. — 6. The florets 
are 5-merous, — 7. The achene is much more slender, longer and lighter 
in colour. — West Australia: Wooroloo, Max Koch, 1907, no. 1873. 
52. Caladenia latifolia R. Br. var. glandula Ewart and Wood, l. c., 
p. 290. (Orchidaceae. — The plant is somewhat more hairy and the 
leaves are shorter and narrower. The chieff differences, however, are 
in the flowers. The perianth segments are dotted closely on the outer 
surface with brown glandular. hairs, especially towards the ends, and 
they are more blunt than in the type Caladenia latifolia. Owing to the
