498 SIR JOHN LUBBOCK ON STIPULES, 
equal in size those of the upper cauline leaves, and in such cases 
they are tipped with a capitate giand. The rest resemble or agree 
with those of Circea Lutetiana. 
TURNERACES. 
In Turnera aurantiaca, Benth., the leaves are alternate, stipu- 
late, oblong, regularly incurvi-nerved, subcoriaceous, covered with 
adpressed hairs in their younger stages, glabrescent as they 
become fully developed; the petioles are short, terete, slightly 
dilated at the base and articulated with a slight pedestal on the 
stem, and furnished with two large glands a little below the base 
of the lamina. The stipules are small, subulate, hairy like the 
leaves, and caducous. 
The terminal bud is covered by three leaves, which are con- 
duplicate, slightly imbricate, and finely plaited along the course 
of the incurved lateral nerves. The stipules do not occupy the 
sinus between their own leaf and the younger ones, but le over 
the latter, and being small, can afford but little protection. 
Axillary buds are somewhat sheltered between the stem and the 
petiole, but are more efficiently protected by their own covering 
of hairs. 
Turnera ulmifolia, Linn., var. elegans, Otto, has the leaves 
lanceolate-elliptic, alternate, tapering into the petiole, pubescent 
above and on the nerves beneath; petiole short, slender, bi- 
glandular in the middle, densely pubescent, very slightly dilated 
at the base. I could see no stipules. 
The terminal growing bud consists of numerous leaves folded 
along their middle and involute at the edges, and standing erect 
round the younger members, thus protecting them. They attain 
considerable size before expanding. Their petioles and principal 
nerves are densely covered with an adpressed pubescence, which 
in itself must afford a considerable amount of protection. At 
the very base of the petiole, on each side of it, is a denser tuft of 
longer hairs in the position where stipules should be, and as is 
the case in 7. aurantiaca. 
The axillary buds are also protected in their young stages by 
the petioles and the clothing of hairs already mentioned.

In Tetragonia erystallina, L’ Hérit., the leaves are broadly ovate 
or triangular, fleshy, alternate, exstipulate, petiolate, densely
