PITCHERS, STIPULES AND TENDRILS. 229 
lary stipuline bud however is not a flower bud, or rather was 
not; this species subsequently produces a leaf bud from the 
axil of tendril. In it the stipule are nothing but the lower- 
most lobes of the leaves. 
Thus the apparent anomaly of opposite leaves in stipulæ 
accompanied with genuine alternate leaves, is done away with, 
for in Leguminose, Passifloree, and Cissi, the stipule are 
nothing but the lowermost pinnule! ! 
Apocynum cristatum.—Pl. 58. IV. 
l. Apex of axis, anti-penultimate leaves and penultimate 
seen between them. 
2. Same antipen. : leaves removed ; shews one penultimate, 
the two ultimate, the last punctum (or the developing leaves 
rather), and the state of the cilize of ultimate pair of leaves. 
3. The same in another view, one ultimate leaf removed 
shews the punctum or disc, and the two young leaves : no cili. 
4, 5, 6, 7. Represent leaves seen in front, shewing the 
development of cilis in their axilla, these are deficient in 
No. 7, the youngest of the four stages. 
8. A node, with stipuliform ciliz. 
Michelia champaca.—Pl. 58. V. 
l. Ultimate leaf, stipular base opened, shewing the last 
punctum ; one stipular dilatation removed. 
2. The same in front, development of lamina seen. 
3. Another, apex of a branch; penultimate leaf and its 
stipular dilatation opened out, shewing the ultimate leaf. 
4. Ultimate leaf of ditto 
3a. Represents the same Yom another apex of a branch. 
7. Young leaf detached spread open, to shew the evident 
continuity of the stipule with the petiole, and that the form 
of the parenchyma of the lamina or stipule does not depend 
"upon the presence of vessels. 
5. Front view of a young leaf and stipule. 
6. Ditto lateral. 
Leriodendron grandiflorum shews that its stipule belong to 
the leaves ; firstly, by the scar which is continuous with the 
margins of that of the petiole; secondly, by its buds, which 
are imbriated with scales, the outermost of which bear on
