of the next older pair, so that all fit very closely in bud.

Buddleia auriculata—1. a,a, two of the oldest unexpanded leaves of a bud, X 2; 
8, stipule. 2. a, unexpanded leaf, underside; 4, 5, first expanded pair of 
leaves, X 2; s, stipule. 3. d, d, third older pair of expanded leaves, x2 ; 
8, stipule. 
In Buddleia Colvilei, Hook. f., the leaves are opposite, decus- 
sate, petiolate, but sessile in bud, tomentose on both surfaces 
with hairs of a pale rusty colour, especially in the early stages ; 
petioles concave above, dilated at the base, where they are slightly 
connate or connected by a rim across the stem. 
The terminal bud is protected by each successive pair of leaves, 
which are flat, adpressed face to face in bud, and the outer pair 
attain considerable size before expansion. The edges of the next 
younger pair of leaves are exposed before the expansion of the 
older ones, but are protected by tomentum. 
The axillary buds are protected by the dilated bases of the
