228 STR JOHN LUBBOCK ON STIPULES, 
apparently functionless, so far as the terminal bud is concerned. 
This is the case, for instance, in Hutaxia myrtifolia and Spartium 
junceum (fig. 5), where the pedestals of the petioles are elon- 
gated, concave, and persistent, thus effectively protecting the 
young bud during winter, and subsequently the young leaves, 
aded slightly by the minute, but persistent, stipules. The 
young leaves also are covered with silky grey hairs. 
In Robinia (R. Pseud- Acacia) the winter-bud is protected by 
three short, brown, triangular, persistent scales. They almost 
look like bark, but are densely lined internally with a grey fur or 
tomentum. On the young growing shoots the stipules are 
linear, subulate, slender, and hairy. Ultimately they thicken 
and become woody, brown, persistent spines. They are less 
developed on the upper branches, which need less protection. 
Here, therefore, they serve rather for the general protection of the 
plant than for that of the buds. In other species of the genus this 
protection is afforded in other ways. In R. hispida, for instance, 
by bristly hairs; in R. viscosa, by a gummy substance which 
exudes from small, globular, reddish glands. In the genus 
Lotus the lower leaflets resemble, and have been regarded by 
some Botanists as, true stipules. There are, however, minute 
glandular teeth, which appear to be the true representatives of 
stipules. 
Genera without Stipules. 
Some Leguminose present no trace of stipules. This is, for 
instance, the case in Ulex (U. europeus), where the bases of the 
leaves are dilated. In Sophora (S. MacNabiana and microphylla) 
the protection of the young leaves is effected by their being 
densely covered with short, adpressed, brown hairs. In Cladrastis 
(C. amurensis) &e., again, the growing bud is protected by a dense 
felt of hairs, and the winter-bud is covered by from four to six 
scales, 
Genera in which some species have, and others 
have not, Stipules. 
In certain genera some species have, and others have not, 
stipules. Thus in Genista tinctoria the stipules are subulate- 
triangular, acute, short, and seated on the persistent and elon- 
gated pedestal of the leaf. In the bud they oceupy the space 
left where the leaf narrows to the base, and it almost seems as if 
they had been separated from the leaf so as to allow it to become
