 FROM NEW SOUTH WALES. 



By R. T. Baker, F.L.S., Assistant Curator, Technological 



Museum, Sydney. 



(Plates VIII. -IX.) 



Acacia Dawsoni, sp.nov. 

 (PL VIII.) 



A dense, virgate shrub rarely exceeding 5 feet in height, with 

 erect, terete branches, branchlets minutely pubescent, finally 

 flattened or angular, with decurrent lines, showing minute 

 resinous dots. Phyllodia narrow, linear, narrowed at both ends, 

 straight or slightly falcate, obtuse or with a minutely recurved 

 point, under 5 inches long, about 2 lines broad, rigid, many- 

 nerved, the veins distinct, and one or two more prominent than 

 the rest, anastomosing here and there, gland present on the upper 

 edge at the base of the phyllode. Peduncles minutely pubescent, 

 1 line long, (4-6 forming a raceme much shorter than the phyllode), 

 bearing each a few flowers (4-6), mostly .3-merous. Calyx about 

 half the length of the corolla, deeply lobed, slightly pubescent. 

 Petals glabrous, slightly ribbed, cohering to the middle at first, but 

 eventually' becoming free. Pod linear, straight or slightly curved, 

 glabrous, under 2^^ inches long, 1 line broad, black ; valves 

 convex over the seeds, slightly constricted between them. Seeds 

 elongated, longitudinal, funicle thickened under the seed, with one 

 fold, becoming filiform towards the placenta. 



Ilab. — Rylstone only, just outside the town, near the angle 

 formed by the Ilford and G-len Alice Roads, where it was first 

 pointed out to me by Mr. J. Dawson, L.S., after whom I have 

 named it.
