or thick, the endocarp hardened into 2 pyrenes, furrowed on each side of the 
commissural edge or curved into spurious empty cells, the endocarp quite distinct 
as in other Avail area, hut not so succulent. Albumen even. — Shrubs more or 
less clothed with a stellate tomentum. Leaves petiolate, undivided, entire. 
Umbels pedunculate, in large terminal panicles. Flowers articulate on the 
pedicel. 
The genus is limited to Australia. It is usually placed in Vmbellifene, but the structure of 
the dowers and fruit, as well as the habit, are much nearer those of Paiut.r, from which the 
genus differs slightly in the cpiearp rather drier, in the foliage and the stellate tomentum.

Fruit thick, with narrow wings on each side. Endocarp curved into 
spurious cells on each side of the inner angle of the pyrene. Leaves

1. A. pterocarpa (fruit winged), Heath. FI. Austr. iii. 879. A slender 
shrub fir. Hill). Leaves on long petioles, cordate-lanceolate, often peltate, 0 to 
lOin. long, densely floccose-tomentose on both sides as well as the leafy branches. 
Panicle very large, with narrow leafy bracts under the principal branches. 
Umbels dense, many-flowered, on short peduncles. Pedicels rarely longer than 
the flowers. Disk scarcely prominent. Fruits without the wings ovoid-oblong, 
thick, about 3 lines long, slightly furrowed ; the endocarp forming 3 collateral 
cells in each carpel, the 2 lateral ones empty, the central one enclosing the seed ; 
the epicarp expanded at the commissure into a rather broad wing, often not 
apparent till the fruit is quite ripe.

2. A. floccosa (tomentum dense and loose), DC. Mein. thnbell. 80 /. 5; 
Prod. iv. 74; Benth. FI. Austr. iii. 879. A shrub attaining from 10 to 80ft., the 
young branches inflorescence and under side of the leaves clothed with a dense 
floccose tomentum. Leaves from ovate-lanceolate to lanceolate, tapering into a 
narrow point, rounded at the base or slightly cordate, the larger ones sometimes 
almost peltate, 4 to 8in. long, glabrous on the upper side, the floral ones small, 
linear-lanceolate, or the upper ones reduced to small bracts. Umbels numerous, 
many-flowered, in a large terminal panicle. Petals woolly-tomentose outside. 
Disk with a slightly raised margin. Fruit nearly 2 lines broad, flat, not winged, 
the endocarp of each carpel sometimes grooved or folded towards the commissure, 
but not curved into spurious cells. — fioht.r jlnrripes, Sieb. PI. Exs.

3. A. longifolia (leaves long), Heath, ia Hue;/. I Aim a. .75, and FI. Austr. iii. 
380. Nearly allied to the narrow-leaved varieties of A. jloccosa, but the leaves 
much narrower, the panicle more slender, with fewer flowers to the umbel and the 
calyx-teeth more prominent. Leaves linear-lanceolate, acuminate, 8 to Sin. long 
and rarely above Jin. broad, glabrous above, with a close white or looser and 
floccose tomentum underneath, or rarely almost glabrous. Fruits rather larger 
than in A. Jloccosa. 
Hab.: Brisbane River, Moreton Bay, A. Cunningham, F. r. Mueller, and others. 
Some specimen;; are very difficult to distinguish from the narrow. leaved one?-, of A. tioccosa : 
others, come near to the longer-leaved ones of A. letlifolia. llenth.
