230 DEVELOPMENT OF LEAVES, 
the back near the apex, a small lamina, which gradually dis- 
appears, leaving the midrib of the petiole and its dilated 
margins. 
Results. 
That the ciliolar stipulz of the Apocynez are mere cellular 
growths of the space of the node between the leaves, and 
‘subsequently all round. 
Still they appear to be developed from the base of the 
leaves towards the centre of the interfolium. : 
They remain always? cellulàr, and are sometimes as much 
developed as some stipula. 
- That the stipules of Michelia are dilated; parts of the 
petiole united with it throughout its whole length. 
hat these stipule are altogether analogous to those of 
Aralia, and Nandina. 
— That the laminar part is first developed ; that the difference 
between these stipule and the lower pairs of pinnules is ony 
one of eye corem of angulation of their bases.

1. Ultimate leaf, with nascent stipula. 
2. Stipulz alone. 
In this as in Rubiacee there is no connection between the 
leaves and stipula. 
In Rubiacez, the interpetiolar stipulae are rudimentary 
leaves of independant origin ; they alternate with the leaves to 
which they are usually referred, present generally (in Ixora, 
etc.) no traces of union, and the central vein is the largest. 
The next leaves to them are opposed to them ! but this may 
not be true opposition, which would be a strongish objection.

3. Apex of branch. 
4. Another, ditto less developed. 
5. Ultimate leaf, and two stipula.
