 fully half as long as the corolla. Petals smooth, with the midrib slightly 

 prominent. Pod linear, straight, flat, l-^to 2 lines broad. Seeds longitudi-

This species differs from A, trinervata chiefly in the long narrow phyllodia, not pungent, 

 when very narrow they are almost Hke those of the Calami formes. In some garden speci- 

 meos the nerves ahnost disappear as represented in the above quoted figure ; and thea it is 

 not very easy to distinguish them from those specimens of A, viscidula in which the nerves 

 are very faint.

 acute with the point usnally incurved, 1^ to 3 or rarely 4 in. long, from 1 line 

 broad in the nan-ow, to 3 or 4 lines in the broad variety, with 2 or 3 slightly 

 prominent nerves and when broad a few faint ones between them, and oiten 

 marked with seniitransparent glandular dots. Peduncles solitary or in pan's,
