380 ■ XL. LEGUMiNOSiE. [Jcacia. 



Calyx broad, eup-sliaped, shortly tootlied, scarcely half as long as the corolla. 

 Petals striate, but smaller and less rigid than in J. imj?ressa. Pod 1 to I j 

 in. long, flat but thick and almost woody, obtusely hooked at the end, about 

 2 lines broad above the middle and gradually narrowed into a long stipes, 

 obliquely veined, partitioned inside between the seeds. Seeds oblong, obli4ue; 

 funicle slightly folded and gradually dilated into a cup-shaped aril at the base 

 of the seed.

A. imnressa. F, Miiell 



A tall 



shrub, the branches slightly angular, more or less pubescent as well as the 

 foliage, Phyllodia obovate or obovate-obloug, very oblique, undulate, obtuse 

 or with a small glandular point, ^ to f or rarely 1 in. long, with 3 to 5 nerves 

 more prominent than in A. translncens, and anastomosing veins. Peduncles 

 about as long as the phyllodia, bearing each a globular head of about 12 to 

 20 flowers, mostly 5^merous. Sepals distinct or slightly coherent, spathulate. 

 Petals rigid and striate, united at the base. Pod straight or nearly so, thinly 

 coriaceous, flat with thickened margins, about -J in. broad, very glutinous and 

 villous. Seeds oval-oblong, transverse, the central area much depressed; 

 fuuicle forming several folds, the last 2 or 3 dilated into a rather small anl at 

 the base of the seed.

D. Oligoneur^.— Phyllodia above \ in. and mostly above 1 in. long, 

 oblong lanceolate or linear, straight or slightly falcate, with 2 or 3 nerves 

 feintly or not at all veined between them and usually not glutinous. 



Although .this subseries is generally distinct from the nest two by the phyllodia with only 

 2 or 3 prominent nerves, yet the A. Simsii is very variable in this respect, connecting the 

 Oliffoneurte with the Nervosa^ aud A. sub^orosa, a vcfy faintly nerved species, has the rcM- 

 nous foliage of several of the Nervosce.

 and often glaucous, or the upper leaves and inflorescence of a golden-yel ow. 

 Phyllodia from obovate to oblong-lanceolate, obtuse aud mostly with a callous 

 recurved point, \\ to 3 in. long in the commonest form, 1 to \\ in the sbort- 

 leaved varieties, narrowed at the base, coriaceous, with 2 more or less proim- 

 nent nerves, penuiveined and with nerve-like margins. Eacemes of few glo- 

 bular heads with a flexuose rhachis aud short peduncles, or reduced to asuigle 

 peduncle with a single head, of 20 to 30 flowers, not very small and mostly 

 5-merous. Calyx sinuate-toothed and petals smooth as in A, saliclna. ro 

 elongated, nearly straight, flat, (foriaceous, about 3 lines broad. Seed no
