484 SIR JOHN LUBBOCK ON STIPULES, 
the axillary bud; but in the following spring, after the leaf has 
fallen from it, an outgrowth is produced from the stem itself in 
front of the pedestal, and this rim, together with the pedestal, 
forms a lipped cup enclosing the buds just about to develop. 
LEGUMINOS2#. 
In Petteria ramentacea, Sieb., the leaves are alternate, stipu- 
late, digitately trifoliolate, petiolate, densely tomentose in the 
young state, and silky above, but subglabrous when mature. 
The stipules, which have been described as small and obtuse or 
obsolete in the early stages of the growth of the leaves, appear to 
be entirely absent; but careful removal of the tomentum covering 
them as well as the petioles shows them to be small, intra- 
petiolar, and slightly connate in front of the petiole, completely 
covering the still minute axillary bud. The terminal bud of the 
elongating shoots in spring is protected by the numerous un- 
folded leaves, 3-5 of the older of which completely surround the 
younger ones, as well as the rudimentary flower-buds where such 
exist. All are likewise densely covered with a tomentum. 
Apparently all the terminal buds, whether they terminate in an 
inflorescence or not, die during autumn or winter; so that the 
young growths in the succeeding spring are lateral. 
The leaves are deciduous, but their stipules are persistent, 
and swell up or grow to considerable size, becoming thick and 
fleshy. Every lateral bud is therefore completely covered and 
effectually protected by the pair of stipules belonging to the leaf 
of the preceding year. These stipules, as well as the persistent 
pedestal of the leaf to which they are attached, are densely lined 
on the inner face with pale-brown hairs like a thick fur, although 
glabrous and dull olive-green externally. 
Furthermore, the stipules being slightly connate in front of 
the petiole, the scar of the fallen leaf gives the impression that 
the latter was inserted on the back of the stipules. 
In Caragana arborescens, Lam., the stipules are variable ; but 
those of the leaves on the elongated branches are subulate, spi- 
neacezt, and adnate to the much dilated and semiamplexicaul, 
persistent pedestal of the leaf, which has a narrow membranous 
margin. The winter- and terminal bud is protected by numerous 
much-dilated, membranous, emarginate or bifid scales, which are
