with a single cell and ovale ; styles 2, often united at the base. Fruit ovate, of a 
single carpel, crowned by the calyx-limb, compressed from front to back, 5-ribbed, 
one face (the broad commissure ?) nearly flat with 1 rib, the other (the back ?) 
convex with 2 ribs, and 1 rib at or near each margin. Vittae none. Seed filling 
the cavity. — Herbs, either annual or with a perennial rootstock or woody or tufted 
base. Leaves toothed or ternately divided. Umbels simple, surrounded by a 
radiating involucre of herbaceous or coloured and often very tomento.se or woolly 
bracts exceeding the flowers. Flowers often very numerous, all with apparently 
perfect stamens and styles, but the outer ones often males by the abortion of the 
ovary, rarely all perfect. 
The genus is confined to Australia. The characters upon which it has been divided appear to 
me to be too artificial and too little in correlation with each other to serve even for sections. —

1. A. Helianthi (Sunflower-like), Labill. ' PI. Nor. Holl. i. 67 t. 
92; Benth. FI. Austr. iii. 867. Flannel Flower. Erect, apparently 
perennial, 1 to 2ft. high, covered with a soft dense almost floccose or 
woolly tomentum, rarely wearing off from the upper side of the leaves. 
Leaves twice 3-partite, with linear or oblong-linear mostly obtuse seg- 
ments, entire or again 2 or 3-lobed. Umbels dense, on long stout peduncles. 
Involucre radiating to a diameter of 2 or 4in ., consisting of 10 to 18 
coloured softly tomentose bracts. Flowers on filiform pedicels of 1J to 2 lines, 
but so numerous as to form a dense head of Jin. to fin. diameter, the outer ones 
all males, the central ones perfect, both in numerous rows. Calyx-rim hairy, 
transparent, about J line long, deeply divided into obtuse linear lobes. Petals 
none. Disk-lobes oblong, gland-like, adnate to the entire base of the style. 
Fruit about 2 lines long, covered with long silky hairs. — Bot. Reg. t. 654 ; DC.

2. A. minor (smaller), DC. Prod. iv. 83 ; Benth. FI. Austr. iii. 368. The 
smaller Flannel Flower. Stems from a perennial base, long and slender, diffuse 
or ascending, glabrous or slightly tomentose or rarely silky-hairy. Leaves small, 
on short petioles, 3-partite, with cuneate or linear segments usually 3 to 4 lines 
long, entire or 2 or 3-lobed, glabrous above, white-tomentose underneath, rarely 
silky-hairy. Umbels small, on long slender peduncles. Involucre radiating to 
about Jin. diameter, the bracts lanceolate, acute, densely white-tomentose on the 
upper side, glabrous on the back, at least along the centre. Flowers very nume- 
rous, the males in several rows at the circumference, the perfect ones in the 
centre, all on short very hairy pedicels. Calyx-limb deeply divided into acute 
lobes. Petals none. Disk-lobes sessile, with the styles between them distinct 
from the base. Fruit about 1 line long, hairy. — Eriocalia minor, Sm. Exot. Bot.
