CORCHORUS LONGIPES, n. S])., 1898. 



A prostrate diffuse undershrub, with several wiry branches, 

 radiating to one foot or more in diameter, sparsely short 

 glandular hirsute. Leaves glabrous or slightly stellate-hirsute, 

 oblong-lanceolate, bluntly pointed, somewhat attenuate at the 

 base, coarsely serrate-crenate, about 10 mm. long, on stalks about 

 one-third the length of the leaf. Stipules broadly and obliquely 

 triangular, toothed, or simple. 



Peduncles about 10 mm. long, bearing one or two pedicellate 

 flowers in the axils of two small obliquely triangular bracteoles 

 connate on one side, and forming a slight incomplete cup ; 

 pedicels about half the length of the peduncles, both with minute 

 glandular hairs. 



Sepals broadly lanceolate, acuminate, 3.5 mm. long, almost 

 glabrous. 



Petals bluish-white, narrow- spathulate, attenuate into a long 

 claw, midrib distinct, 4 mm. long. 



Stamens five, free, longer than the ovarium, 2.5 mm. long. 



Ovarium thickly beset with short stellate-hairs, 2 mm. long, 

 terminated by a much abbreviated style. 



Capsule on straight not recurved pedicels, oval oblong, 

 obtusely rounded at both ends, 6 mm. long, exteriorly minutely 

 stellate-hairy and contracted between the seeds ; valves five, 

 membranous. Seeds somewhat horse-shoe shaped, smooth, 12 to 

 16 in each cell, without transverse partitions between them. 



Mount Lyndhurst Run in the neighbourhood of Farina, South 

 Australia. — Max Koch. 



This species differs from its Australian congeners, which are 

 subshrubby in habit, in many particulars ; of these may be 

 noted the long peduncles, the erect capsule, the inconspicuous 

 vestiture of glandular hairs, the fewness of stamens, the shape 

 of the numerous seeds. In general appearance it resembles 

 C. vermicular is. 



Acacia papyrocarpa, Bentham. 



It is with some hesitation that I refer the rigens-YikQ Acacia 

 from Mount Lyndhurst to the rare A. papyrocarpa, on account
