Gnetiim africanum , with Notes on Gnetum scandens. 1107 
In the younger examples of female inflorescences of G. africanum, 
the state of affairs is similar to that in G. scandens . The great extent 
of the node in this species (Fig. 2, PL LXXXVI) is, however correlated with 
a disturbance of the arrangement of the vascular system over a greater 
distance, and indeed the course of the undisturbed ring characteristic of the 
internode is in this species relatively very short. 
In Text-fig. 3 is seen a diagram of the course of the bundles 
Text-fig. 3. Letters as before ; also f = branched fibres; H = hollow stem opposite ovule ; 
BC = bract cupule; c = nodal cushion ; TR = transfusion tissue; lom = small bundles arising 
from main series and augmenting series OB ; OM = bundle arising from main series and augmenting 
series OIV; OIV = inverse series turning down to supply ovule; P, o.IN, I.IN = bundles supplying 
perianth, inner integument and outer integument respectively. 
through the node of an old female inflorescence of G. africanum . As 
before, the bract bundles (b) are seen to originate from the main bundles, 
and as they pass out they give rise first to a series of inversely orientated 
bundles (BIV) and then to some normally orientated ones (OB), both of 
which supply the ovule. Both series are augmented from the main series. 
In the oldest inflorescence I examined, only a few small bundles (lom) were 
added to the outer series, which still is chiefly composed of bundles derived 
from the bract bundles. But a large number of the inversely orientated 
bundles forming the inner series come directly (miv) from the main bundles
