each a very small head of 6 to 10 small flowers, mostly 5-merous. Calyx 

 very short, truncate or sinuately toothed. Petals smooth. Pod linear, flat, 

 with nerve-like margins, 1| or scarcely 2 lines broad, on a rather long stipes. 

 Seeds nearly globnlar, the funicle filiform to the end, but not seen quite ripe,

75. A, ulicina^ Meissn. in PL P/^eiss, ii. 202. A rigid spreading gla- 

 brous shrub of 2 to 4 ft., the branches sulcate-striate, the smaller short ones 

 spmescent or reduced to small thorns. Phyllodia linear, obtuse or obliquely 

 mucronate, often 1 in. long on the main branches, | to |- in. on the side ones, 

 obscurely l-nerved. Peduncles short, bearing each a globular head of about 

 20 flowers, mostly 5-nierous. Calyx obtusely lobed, half as long as the corolla, 

 "etals smooth, but with pronn'nent midribs. Pod linear, very flexuose, 1 to 

 la Hues broad, much contracted between the seeds. Seeds obovate-oblong, 

 thick; the funicle with a first short filiform fold, the next thickened into a 

 club-shaped, almost hood-shaped aril, almost as long as the seed.

 ^ ^'Congesta and A. idiom orpha). Phyllodia from oliovate to lanceolate, 

 rarely above 1^ in. long, more or less undulate, with a central nerve and 

 usually nerve-like margins, the margiual gland very small and obscure or

 acuminate or phyllodia-like. Peduncles IdicaJed.
