696 PLANTS OF NEW SOUTH WALES, 



A. TRiPTERA, Benth. B. Fl. ii. 323, var. Lyxdoni, R.T.B. 



(Plate XXV.) 



A tall, dense shrub with long pendent branches, glabrous. 

 Phyllodia numerous, decurrent on the stem, rigid, inclined to 

 erect or running out obliquely from the stem, not recurved as in 

 the type, almost triangular in shape ; the upper edge curving 

 upwards to the pungent point, sometimes obliquely lanceolate 

 when in fruit, 1 to 2 inches long, about 6 lines broad, striate with 

 several prominent nerves, without any marginal gland. Peduncles 

 solitary or 2 together, mostly at the ends of the branches, each 

 bearing a cylindrical spike of f inch. Flowers not crowded, fairly 

 large, 4-merous. Calyx smooth, short, broadly lobed. Petals 

 smooth, separating when fully in flower. Pod curved, 3 to -t 

 inches long, 2 lines broad, valves coriaceous, contracted between 

 the seeds. Seeds longitudinal, funicle folded 3 or 4 times upon 

 itself, slightly thickened under the seed. 



Hah. — Round Mountain, Coonabarabran (S. Lyndon). 



This variety is very distinct from the type as described by 

 Bentham and figured by Baron von Mueller (Ic. Au. Ac. ix.) The 

 phyllodia have quite a characteristic shape, there being an 

 absence of the recurved-falcate form mentioned by Bentham. 

 Thev are also broader and thicker, and the flowers are larger than 

 specimens from the interior. When placed for comparison in 

 juxtaposition with the type, its characters stand out as very 

 marked, but still there is no distinctive feature either in the pod 

 or flower, suflicient to warrant its being raised to specific rank. 



A complete set of specimens was collected by the late Mr. S. 

 Lyndon, B.A.
