bifida, 1-lineari, perianthii segmentis oblongis ; spatha ¢ multiflora

Hab. Between Zanzibar and Uyui: W. E. Taylor, 1886. 
A small plant with stiffish stems § line in diameter, densely 
covered with crisp more or less reflexed linear leaves, some- 
times subopposite, 6-7 lines long by } line broad, with about 40 
sharp outwardly and upwardly directed teeth seated on a trian- 
gular base of several cells; on the branches the leaves are 
smaller (5 lines x } line), with rather fewer teeth (about 35) and 
a blunter tip; the conspicuous midrib is united by transverse 
veinlets to two parallel but weaker longitudinal veins, and the 
rectangular areas thus formed are filled with cells longer and 
poorer in chlorophyll than those forming the rest of the 
mesophyll. Intrafoliar stipules are absent, but the somewhat 
enlarged leaf-base bears a pair of teeth on either side. The male 
inflorescences are sessile in the leaf-axils on the main shoots, the 
cup-like spathes, about } line long, containing several flower- 
buds; the three short stamens bear two pendent anther-cells, 
each with a pointed tip. The female flowers are borne on the 
ultimate branches, the single-flowered axillary flask - shaped 
spathes being 1 line in length and without teeth; the perianth- 
tube is ? in. long, the colourless oblong segments about 4 line, 
the papillose stigmas are also } line in length. The brown 
broadly spindle-shaped fruits are 1} line long, or about 2 lines 
including the beak. 
Resembles ZL. tenuis, mihi, in the characters of the female 
spathe and flower, but differs in having larger, linear, crisp 
reflexed leaves with more depressed teeth.
