 To this belong the great majority, but not all of the Kiog George's Sound specimens, occur-

Series VII. Plurinerves. — Phyllodia vertically flattened, obtuse or 

 with an innocuous or recurved point (rarely pungent when the phyllodium is 

 broad), with 2 or or more longitudinal nerves. Flowers in globular heads . 

 on axillary peduncles, either solitary or clustered or shortly racemose. 



A. AuMAT^E.— Stipules spinescent. Phyllodia falcate, subulate-acuminate 

 or almost pungent. 



These correspond to the subseries Annatee of Wninerves, except that the phyllodia are 

 larger. 



16i. A. scalpeUiformis, Meissn. m PI Preiss. ii. 200. A tall shrub, 

 glabrous or the striate branches pubescent. Phyllodia obliquely triangular- 

 lanceolate, acute and pungent-pointed, I to Ii in. long, 3 to 5 lines broad, 

 tapering at the base, 2-iierved, penuiveined, with neiTe-like margins, with a 

 gland on the prominent angle of the upper edge. Stipules setaceous-spines- 

 ceut, spreading. Peduncles solitary, bearing each a globular flower-head, 

 rioivers not seen perfect, but the withered remains have a broad short lobed 

 calyx and 5 petals separating almost to the base. Pod very long, scarcely ly 

 lines broad, readily twisting, with broad very thick obtusely dilated sutures, 

 peeds oval-oblong, longitudinal, the last 2 or 3 folds of the funicle thickened 

 into a small aril under the seed.
