216 SIR JOHN LUBBOCK ON 
stipules, just commencing to burst in spring. A gland is here 
again situated just above the bud. The stipules are generally 
horizontal towards the apex of the shoots. 
Acacia Hindsii, Benth.—The leaves are abruptly bipinnate, of 
Figs. 14, 15, 16.

large size, with numerous pairs of pinne and very numerous, 
small, linear-oblong, obtuse, slightly faleate leaflets, glabrous, 
persistent. Petiole subterete, grooved above, dilated and thickened 
at the base, articulate with a pedestal or elevation of the stem. 
The stipules in their early stages are very small, fleshy, sub- 
ulate and pointed, attaining a great size, spinescent, glabrous 
green in the early stages, ultimately brown, persisting long after 
the leaves have fallen, and attached to the pedestal below the 
articulation of the petiole. While still in bud they lie in the 
concave space between two leaves. As the leaves fall away, * 
portion of the petiole decays more slowly. In the meantime the 
stipules enlarge, becoming spiny, divergent, brown, strong? 
ridged laterally, and 220-28 cm. long. The pedestal below ™ 
articulation also enlarges, till it is 12-18 mm. long, becom!ng 
large, woody, and brown.
