HORN EXPEDITION^ — BOTANY. 187 



G. Diagnosis of new Genus and Species. 



Acacia Cowleana, Tate. 



Slender, erect, about .six to eight feet high ; the foliage and young branchlets, 

 ashy or iioary with very minute appre.ssed hair.s. Branciilets stout, acutely 

 trigonous. Phyllodia lanceolar-falcate, narrowed at both ends, mostly live to 

 seven inches long and three-fourths wide at the middle, coriaceous, with three 

 prominent parallel veins, the interspaces with eight to ten secundary veins which 

 frequently anastomose. Stipules njinute lanceolate. Spikes .shortly pedunculate, 

 one or two together, up to two inches long. Flowers distant or distinct, 

 pentamerous. Calyx very much shorter than the corolla, minutely puljcscent, 

 with five short blunt denticulations. 



Corolla deeply five-cleft, smooth ; each segment narrow, oblong, with an 

 apiculate tip ; yellow, brown at the base. 



Ovary pubescent. Pod (not seen ripe) exceedingly tlat, long and narrow, 

 four to five inches long, and one-seventh wide, not twisted, glabrous or nearly so. 



Seeds longitudinal ; funicle very long and slender, loosely double-folded at 

 about the middle, beneath the seed. 



The species name is in compliment to Trooper Cowle, who conducted a section 

 of our party to Mount Olga, and in various other ways promoted the scientific 

 objects of the Expedition. 



Among members of the series Juliflora", this new species finds a place in the 

 section Falcatte near to A. g/ai/cescens and A. CiinidnghaDiii ; from the second it 

 difTers by its straight pod and thus resembles the former ; from A. glaucesccns it 

 differs by its very long smooth pod, oblong-apiculate petals and by coarser 

 anastomosing secondary venation. 



Acacia frumentacea, Tate. 



A small tree attaining ten or fifteen feet liigh, glabrous and mealy glaucous ; 

 branchlets somewhat angular. Phyllodia nari'owly ol)long, apex obtuse, with a 

 minute tip recurved over a subterniinal gland, narrowed at the base, two to three 

 inches long, coriaceous, with a prominent mid-ril) and distinct reticulate veins, 

 pale green, redioicks slender in axillary racemes, shorter than tin; phyllodia; 

 heads globular of about forty llower.s, mostly Lutramerous. Sepals very narrow 

 linear, slightly spathulatc at the end, smooth, free. Pclals distinct or almost so,
