NOTES ON ACACIA. 



473 



Flowers about nine to thirteen in the head, pentamerous, 

 calyx and corolla of about equal length, calyx truncate or 

 nearly so, glabrous except for the tips of the sepals, which 

 are tufted with hairs. Petals glabrous, slightly keeled, the 

 tips a little thickened. Pistil smooth. 



Pod moderately long, and broad, (say 13 X 1 cm.), slightly 

 curved. Margins of the valves thickened and somewhat 

 grooved, the valves more or less wrinkled, the seeds 

 arranged longitudinally, distending the valves without 

 making the pods moniliform. 



Seed with filiform funicle twice encircling it, and termin- 

 ating in a clavate arillus at the top of the seed. The 

 length and contour (whether kinked or not) of the funicle 

 is subject to variation, as in A. rubida. 



Synonym. A. penninervis Sieb., var. angustifolia Maiden 

 in "Wattles and Wattle-barks," 3rd Edition, p. 49 (1906). 

 It was described in the following words: — 



"A long narrow-phyllode form, found only on the South Coast, 

 so far as I know. Phyllodes commonly six: inches long, and under 

 half an inch wide, straight or slightly falcate. The pods are 

 narrower than in the normal form. The young shoots and the 

 rhachises of the inflorescence are sometimes densely covered with 

 golden yellow hairs."

 Flora of New South Wales."
