PLATE LXXXVI. 
Fig. 1. Single node of inflorescence of Gnetum scandens , showing young ovules with projecting 
micropyles borne on a cushion ( [Cits. ) in the axil of the cupule of bracts {Cup.). In. — internode. 
In the right-hand figure are shown the gaps in the cushion from which two of the sunken ovules 
have been removed. (Rather larger than natural size.) 
Fig. 1 A. Single mature ovule of G. scandens on stalk. (Natural size.) 
Fig. 2. Lower portion of inflorescence of G. africanum , borne on naked peduncle. At the 
base of the inflorescence are two bracts in the axil of which was a cushion, but no buds or ovules. 
In. — the very short internode; B.c. = the cupule of bracts; c = large swollen axillary nodal cushion ; 
A.Ov. = abortive ovules; F.Ov. = fertile ovules. (Natural size.) 
Fig. 3 a. Diagram of transverse section through lowest part of node, showing free edge of 
cupule, and base of axillary cushion covered with hairs. Shaded patches on cupule {Cup.) represent 
corky tissue ; c = hairs; shaded lines on inner edge of cupule = mucilaginous layer of cells, x 6. 
Fig. 3 b. Diagram of transverse section through middle of node. The two inner series of 
bundles are seen in pith of main stem ; the outer series has just passed out into the ovules. A.o. — 
abortive ovule with free integuments arising from base; C = peltate projecting portion of cushion; 
F. o. = fertile ovule; P = outer covering; 0.1. = outer integument; C.M. = closed micropylar tube; 
N.c. = nucellar cap; e = embryo-sac. x 6. 
Fig. 4. Single bundle from peduncle, showing space in pericycle ( Pcy.Sp.) crossed by trabeculae ; 
small space on inner edge of bundle {Sp.). V.B. = vascular bundle; F = fibre, x 400. 
Fig. 5. Section through portion of bract cupule. M = mucilaginous layer under upper 
epidermis ; Tr. = transfusion tissue at sides of bundles ; F = fibres, x 78. 
Fig. 6. Part of transverse section through base of ovule, just below level of freedom of outer 
integument (o.I.). N + Id. = nucellus and inner integument; l.f. — lignified fibres, here marking the 
line of separation of outer integument and becoming later the inner zone of the outer integument; 
p = palisade layer; v.b. = vascular bundle; to the left of the bundle is a hypodermal strand of 
tissue with dark-coloured cell-walls, x 78. 
Fig. 7. Longitudinal section through apex of expanded portion of outer integument. F = 
parenchymatous tip; L = lignified series of cells at the termination of fibrous layer; a.r. = outer
