from Gin. to 1ft., and the fine veins more numerous, prominent, and transverse. 
Racemes short with several small globular heads of flowers mostly 5-merous. 
Calyx turbinate, more than half as long as the corolla, shortly and broadly 
toothed, ciliate. Petals smooth, pubescent. Pod 3 to 4in. long, fiat, 2 to 3 lines 
broad. Seeds oblong ; funicle not enlarged under the seed, not folded.

2G. A. penninervis (feather-nerved), Sieb. in DC. Prod. ii. 452; Benth. 
FI. Austr. ii. 362. A tree attaining sometimes 40ft. but usually smaller, glabrous 
in all its parts in the common variety, with angular branchlets. Phyllodia from 
oblong to lanceolate-falcate, more or less acuminate, usually 3 to 4in. long, but 
sometimes twice that length, much narrowed towards the base, 1 -nerved and 
more or less prominently and finely penniveined, the margins usually nerve-like, 
and often but not always a short secondary nerve terminating in a marginal gland 
much below the middle. Racemes rather short but loose, with several small 
globular heads of about 20 flowers, mostly 5-merous. Calyx truncate or shortly 
toothed, not half so long as the corolla. Petals smooth. Pod flat, straight or 
curved, with slightly thickened margins, often 4 or 5in. long, nearly iin. broad. 
Seeds ovate, longitudinal ; funicle long, dilated and coloured nearly from the base, 
extending round the seed and bent back on the same side, so as to encircle it in a 
double fold. — Bot. Mag. t. 2754 ; F. v. M. PI. Viet. ii. 14 ; A. impressa, Lindl.

i. 357, and FI. Austr. ii. 363. A tall and handsome shrub or small tree ; 
branchlets slender, slightly angular, glaucous or mealy-tomentose when young,

callous point often recurved, much narrowed towards the base, mostly 3 to 5in. 
long and 2 to 4 lines broad, 1-nerved, obscurely penniveined, with 1 or sometimes 
2 or 3 distant marginal glands rarely all wanting. Racemes always simple, 
rather slender, much shorter than the phyllodia, the rhachis and peduncles 
usually tomentose. Flower-heads globular, small, with 30 to 40 flowers, mostly 
5-merous. Sepals spathulate, more than half as long as the corolla, ciliate, free 
or slightly adnate below the middle. Petals smooth, usually free. Pod flat, 
straight or nearly so, several inches long, about 4 lines broad, often slightly con- 
tracted between the seeds. Seeds oval-oblong, longitudinal ; funicle with the last 
fold appressed and thickened from the middle upwards into a club-shaped aril,
