268 SIR JOHN LUBBOCK ON 
The axillary buds are long, remain small, and are sheltered in 
the depression or fold at the base of the otherwise expanded 
sheaths. 
The artieulation at the point of union between the lamina 
and the sheath of the leaf of Pothos Loureiri gives it the 
appearance of a compound leaf, and forcibly recalls what exists 
in the species of Citrus, such as C. Aurantium, C. Decumana, &c., 
which have a winged petiole, auricled at the apex and articulated 
with the lamina. Limonia aud Murraya, belonging to the same 
order, have compound leaves, The petioles of Limonia acidis- 
sima are likewise winged. In Phyllarthron comorense the leaves 
consist of 2-5 oblong-cuneate, flat joints, and appear to be dila- 
tations or winged expansions of the common petiole of a com- 
pound leaf. Each joint or piece is generally retuse or truncate 
at the apex. 
Thus, then, the outer scales which protect the winter-bud fall 
into at least seven categories. 
They may be 
1. Pedestals of last year’s leaves, as, for instance, in Pyrus 
Aria. 
- Modified bases of leaves, as in the Maples and Horse- 
Chestnuts. 
. Leaf-blades, as in Viburnum Lantana. 
. Modified leaves, as in Viburnum Opulus, the Willows, be. 
. Stipules, as in the Poplars, Oaks, Beech, &c. . 
- Connate pairs of stipules belonging to the same leaf, as m 
the Elm and Spanish Chestnut. 
7. Connate pairs of stipules belonging to different leaves, 3 
in the Hop, Gardenia and other Rubiacem.

In conclusion, I have to express my thanks to Mr. Thiselton- 
Dyer and the staff of Kew, as also to Dr. Scott, for the facilities 
they have been good enough to give me, and to my excellent 
assistant Mr, Fraser for his valuable aid.
