of thorns or reduced to O. If all are absent there remains 
only a swollen ring. 
. One ,ring” bears two cicatrices of fallen leaves, 1 rudiment, 
1 open space. The second ring produces one leaf and one 
thorn. The third ring gives off two broad-based leaves sug- 
gesting coalescence of the bases with thorns. 
4th ring produces four leaves grown to gether to a pitcher. 
A fasciating branchlet, bears at the top on both sides a leaf 
with axillary bud, and in the middle two leaves turning 
their midribs towards one another and thus coalescing. (‘Twice). 
Top of a stem with 4 stalked blades round the top-bud. 
Two leaves springing side. by side. grown together toa circular

The peculiar shapes, the outcome of different ways of coales- 
cence, cannot duly be described without figures. Chiefly the 
cases of disturbance may be summed up as follows:

Nodi with four thorns (calling to mind the Ephedra-type, 
although this genus bears only two thorns and exceptionally 
three (Masters). 
Nodi with three thorns and one common leaf. 
1) As to the swollen nodi themselves it should be emphasized that they gradually 
swell quite independent of the size of the lea
