156 R. H. CAMBAGE. 



leaflets from five pairs in No. 3 to sometimes fourteen pairs 

 in No. 5; rachis from 5 mm. in No. 3 to sometimes 4 cm. in 

 No* 5, pilose; stipules pubescent acuminate scales 1 mm. 

 long. 



Nos. 6 to 10. Abruptly bipinnate, petiole from 1*2 in 

 No. 6 to 7 cm. in the common petiole of No. 10, pilose, 

 dilated, up to nearly 1 mm. broad, and having a small faint 

 gland in some cases, with a strong nerve along the lower 

 margin, and, in Nos. 9 and 10, often a striated lamina 

 above, No. 6 may often have two pairs of pinnse while No. 

 10 may have five pairs; leaflets from ten pairs on No. 6 to 

 sometimes twenty pairs on No. 8, up to 1 cm. long, 2 mm. 

 broad; rachis from 2'2 to 5*5 cm., pilose; stipules as in 

 No. 5. 



Nos. 11 to 20. In some cases these may be phyllodes, but 

 usually are bipinnate, having up to eight pairs of pinnse, 

 with common petioles sometimes 10 cm. long, from 1 mm. 

 to perhaps 1 cm. broad, pilose, and with a very faint gland 

 towards the base. Where the lamina is about 3 mm. broad, 

 the strong nerve is about 1 mm. from the lower margin, 

 while there is a finer nerve towards the upper edge, the 

 nerves often being confluent at both ends. When the 

 lamina is 1 cm. broad both nerves are conspicuous, but the 

 lower is the more prominent, the remainder of the lamina 

 being marked with several finer, longitudinal, anastomosing 

 veins, and sparsely covered with fine hairs. 



The phyllodes on a plant several feet high show three 

 nerves, the central, which has been evolved from or corres- 

 ponds to the strong nerve mentioned in connection with 

 leaves 6 to 10, being the most prominent. 



In rich soil and a moist climate a seedling of this species 

 may reach a height of five feet before showing any phyl- 

 lodes, while it may sometimes develop phyllodes at only a 

 few inches high when grown in a pot.
