ceeding the perianth, the slender stigmatic end scarcely distincts.—Meissn. in Pl. Preiss. i. 593, and in DC. Prod. xiv. 471.

W. Australia. King George's Sound or to the eastward, Baxter, Drummond, Preiss, n. 500.

Series 5. Niveæ.—Low shrubs with a creeping trunk and very short ascending flowering stems bearing one or few ovoid flower-heads surrounded by long floral leaves. Leaves pinnate with numerous rigid segments, the margins usually but not always revolute and white underneath.

The species here enumerated differ in habit from all except some states of D. vestita and two species of the section Aphragmia, which require further comparison with D. Preissii as to their carpological characters.

22. D. nivea, R. Br. in Trans. Linn. Soc. x. 214, Prod. 398. A dwarf shrub, the stems sometimes scarcely any besides the underground or creeping trunk, rarely ascending to nearly 1 ft. Leaves 4 to 8 in. long, pinnate, divided almost or quite to the midrib into numerous regular triangular or falcate segments, obtuse or rarely acute, 1 to 3 lines long, verying in breadth, those towards the end of the leaf usually separated by acute sinuses, the lower ones more distant and decurrent, or all different in this respect in different leaves, all rather thick, with revolute margins, white underneath. Flower-heads terminal, closely surrounded by long floral leaves. Involucre ovoid, usually about 1 in. long; bracts numerous, narrow, glabrous or minutely ciliate, or with the ends more or less woolly, the outer short ones sometimes subulate, the inner ones obtuse or scarcely acute. Perianths about as long as the involucre, loosely villous except the undivided base, the limb scarcely 1½ lines long. Style considerable longer than the perianth, with a small narrow stigmatic end slightly thickened at the base. Capsule obovate-falcate, about ½ in. broad.—Meissn. in Pl. Preiss. i. 594, and in DC. Prod. xiv. 472; Banksia nivea, Labill. Voy. i. 411, t. 24; Josephia rachidifolia, Knight, Prot. 111.

W. Australia. King George's Sound, R. Brown, and many others; eastward to Cape Legrand, Labillardière; northward to Vasse, Swan, Moore and Murchison rivers, Drummond, Preiss, Oldfield, and others.

This species, evidently widely spread in the sandy plains of W. Australia, includes Drummond's, n. 64, 125, 134, 1st coll. n. 640, 641, 645, 2nd coll. n. 346, 5th coll. n. 419, and Preiss's n. 506, 510, and (according to Meissner) 504 and 508, besides numerous specimens from other collectors. Drummond's 4th coll. n. 313, with rather longer flowers (D. brownii, Meissn. in Pl. Preiss. i. 595, and in DC. Prod. xiv. 472), Preiss's n. 511, from near Pointwater, with the involucral bracts rather more woolly at the end (D. Lindleyana, Meissn. in Pl. Preiss. i. 598, and in DC. l.c.); and Drummond's 6th coll. n. 212, from between Moore and Murchison rivers, with the leaf-segments rather narrower and more distinct than usual (D. stenoprion, Meissn. in Hook. Kew Journ. vii. 122, and in DC. Prod. xiv. 473), appear to me to be scarcely distinguishable from specimens of the commoner forms even as marked varieties.

23. D. arctotodis, R.Br. Prot. Nov. 39. A dwarf shrub with the habit of D. nivea. Leaves much more rigid, 4 to 8 in. long, deeply divided into numerous linear-falcate rigid acute lobes, 2 to 4 lines long,
