14 P. julifl6ra (D. C. prod. 2. p. 447.) spines stipular, 



in each flower. Legume continuous, dry, 2-valved. — Shrubs or 

 trees, very variable in habit and leaves. Spines stipular, scat- 

 tered, or wanting. Flowers yellow, white, rarely red, disposed 

 straight, small; leaves w^ith 1-2 pairs of pinnae, each pinna bearing in globular heads or spikes, decandrous, or polyandrous, eleu- 

 from 18-20 pairs of linear leaflets, which are acutish at both ends, therandrous or monadelphous. This is a very polymorphous 



genus, which may hereafter be divided into several genera, when 

 the characters of the species are better known. The barks of 



and are glabrous as w^ell as petioles, with a sessile gland seated 

 on the petiole between the pairs of pinnae ; spikes cylindrical, 



sessile ; legume much compressed. 12 . S. Native of the south many of the species abound to such a degree in tanning principle

Sect. L . Piiyllodine^ (from ^uXXov, j)^y//6w, a leaf; leaves 

 simple). Leaves of two forms, those in seedling plants are bi- 

 pinnate, but in the adult plants the leaflets are abortive, and 

 there only remains the dilated petiole, which is called a 

 phyllodium. Acaciae aphyllae, Wendl. diss. 1820. Flowers in all 

 yellow. The species are mostly natives of New Holland.
