Notes. 
The shoot of the Ash has two nodes at which the leaves are strictly opposite, but 
elsewhere shifting has taken place, the distance between the two leaves of a pair vary¬ 
ing from 3 mm. to 16 mm. Displacement of this kind is not uncommon in the Ash 
and in many other species of plants in which the leaves are typically opposite. 1 
A further departure from the normal phyllotaxy has also been observed in the Ash in 
the form of a two-fifths arrangement of the leaves, 2 and the same abnormality is 
known to occur in several other plants whose leaves are normally decussate. 
On some shoots of the Ash, in the winter condition, it is easy to see that there 
are two buds, one above the other in the axil of each leaf. In other shoots the lower 
bud, which is the smaller of the two, may be very small and inconspicuous, or it may 
be absent. Where there are two buds, the upper one is occasionally raised distinctly 
above the axil, e. g. i to 4 mm. above it. The shoot described in this note shows an 
exceptional case of displacement, one bud being 25 mm. (or a quarter of the length 
of the internode) above the node to which it belongs. In this case an additional bud 
has been formed, so that there are still two buds in the axil of the leaf, the lower being 
the smaller. At some of the nodes of a different shoot, where the upper bud is only 
shifted 3 to 4 mm. above the axil, a very small third bud is again present. A com¬ 
parison of these cases appears to indicate a basipetal sequence of bud-formation; 
hence, where two buds are present, the lower should be regarded as the accessory 
one. 3 
On examining a number of young Ash trees it was observed that considerable 
shifting of leaves (and also of buds) is rarer where the internodes are comparatively 
short, but no more definite relation than this could be discovered by comparing 
measurements of displacements and of internodes 4 in the examples specially studied.

ON THE OCCURRENCE OF VEGETATIVE PROPAGATION IN DRO- 
SERA.—The subject of the present note is the occurrence of vegetative reproduction 
and multiplication, by budding, in two species of Drosera , viz. Drosera rotundifolia , 
L,, and Drosera intermedia , Hayne. The specimens which exhibited this phenomenon 
had been obtained in two consecutive years from near the large pond at Wisley. At 
the time of their collection (July), however, they showed no sign of the budding which 
they later exhibited. 
The plants obtained on the first visit were transferred to the cool greenhouse at 
the writer’s own home, and were grown in saucers on Sphagnum without covering. In 
the late spring of the following year it was noticed that young plants in various stages 
of development were arising from the blades of the leaves. Only a single plant 
developed from each leaf, but in some cases nearly all the leaves of a plant bore such

Leaves in whorls of three also occur in the Ash.
