PLATE 317. 
Dioscorga MALIFouiIA, Baker (Fl. Cap., Vol. VI., p. 248). 
Natural Order, D1oscoREacEAE. 
A dioecious climbing plant, with yellow flowers. Rootstock woody, roots 
tough. Stems slender, wide climbing, glabrous. Leaves alternate, petiolate, blade 
broadly ovate, quite entire, truncate or cordate at base, mucronulate at apex, 7- 
nerved at base, 5 of the nerves reaching the apex of the leaf, the outer one at each 
side only reaching to ? the length of the blade, the whole leaf glabrous and 
shining, dark green above, lighter beneath; petiole 2 to !1 inch long. Flowers of 
the staminate plant in fascicled racemes, | to 3 inches long, the rhachis straight or 
curved; pedicels short, ascending, bracts small, ovate-acuminate. Perianth less 
than 1 line long, yellow, tube very short, segments obtuse. Stamens 6, opposite 
lobes of perianth; pistillate flowers in lax racemes, 38 to 6 inches long, barren 
stamens 6, minute. Ovary inferior, triquetrous, glabrous, two to three times 
longer than the perianth, 3-celled, cells 2-ovuled, ovules superposed; styles 3, very 
short, recurved, stigmas obtuse. Capsule emarginate, triquetrous, 2 to 1 inch long, 
6 to 8 lines long, including the wings, which are 2 to 3 lines wide. Seeds ovate, 
compressed, with a sub-basal wing, half or more the length of the seed, and 
extending as a very narrow line all the way round. 
Habitat : Natau: Inanda, 1,800 feet alt., Wood, No. 753; Northdene Herb., 
Normale, No. 1035; Sanderson, No. 232; Cooper, No. 8247; Gerrard, No. 444. 
Drawn and described from the specimens gathered near Durban, March, 1903. 
This is the second species of Dioscorea figured in this work, the other being 
D. crinita, Hook (Plate 17, Vol. 1). The seeds examined were not quite ripe, but 
the wing in all those seen was as is stated in the description and shown in the 
drawing. The native name of the plant is in-'Tana, and the tough roots are split 
and used to tie round the shaft of the assegai where the iron blade is inserted into 
it to prevent splitting.
