150. A. Leichhardtii, Benih. Brandies slender, terete, hispid witli 

 long spreading hairs. Phyllodia linear-lanceolate, falcate, mucronate, rarely 

 above 1 in. lonj^, the midrib and nerve-like margins prominent and ciliate, 

 otherwise veinless, the marginnl gland about the middle, often ^vanting. Ra- 

 cemes much longer than the phyllodia, slender, with numerous small beads of 

 20 or more flowers, mostly 5-merous. Calyx turoinate, shortly lobed, half as 

 long as the corolla. Petals smooth. Pod very flat, 2 to 4 in. long, about 

 4 lines broad, hispid with long hairs, but not seen ripe.

151. A. crassiuscula, Wendl. Comm.Jcac. SI J. 8. A shrub of several 

 feet, glabrous and often rather glaucous when young ; branches usually acutely 

 angled. Phyllodia numerous, linear, often falcate, with a small oblique pouit 

 or the lower ones obtuse and almost lanceolate, ratlier thick, 1-neryed and 

 veinless, the nerve-like margins often but. not always ciliate, 1^ to 2 in. long 

 in some specimens, above 3 in. in others, 1^ to 2 or in larger ones .3 hues 

 broad, the marginal gland below the middle. Racemes shorter than the 

 phyllodia, w:ith several small dense globular heads of 20 or more flowers. 

 Calyx turbinate, fully half as long as the corolla, ciliate and readily separating 

 into spathulate sepals. Petals often separating, with prominent midribs. 

 Pod linear, rather thick, about 2i lines broad, contracted between the seeds. 

 Seeds in the centre of the pods, but not seen perfect.-r-DC. Irod. u. ^-^o;

Although evidently distinct from all other species I have examined, it is impossible to 

 Refine this one satisfactorily until the fruit shall he more certainly known. It is certamiy 

 Tery distinct from the AVestern plant referred to in * Plantse Preissiana?/ 



152. A. decora, Reichb. Icon. ExoL L 199. A shrub of several feet, 

 glabrous or slightly glaucou^-toraentose ; braiiclilets angular, rhyllodia^lan-

 long, thicker than in J, linifoUa^ l-nervcd, slightly penniveined, with nerve- 

 like margins and usuallv with a gland below the middle. Racemes usually 

 numerous, longer than the phyllodia, with several globidar heads of about z 

 flowers, mostly 5-merous, Calyx shortly lubed, not half so long as the corolla. 

 Pod straight or curved, flat, about 3 lines broad. Seeds longitudnud, close

Perhaps a variety of A, buxifolia, differing only in the longer phyUodia and more nui 

 reus flowers in the heads. Some specimens from 'the Melbourne Botanic Garden, appar 

 of this species, have the phyllodia still longer and narrower.
