404. MR. A. B. RENDLE ON THE 
ACIDANTHERA CANDIDA, sp. nov. Herba glabra ; bulbo globoso; 
caule simplici compresso 1-1}-pedali; foliis tribus gramineis 
subrigidis superpositis; spica laxe 2-4-flora ; spathe valva ex- 
teriore viridi basi purpurascente lineari-lanceolata ; perianthii 
tubo longo tenui segmentis candidis late ovalibus, quam stamina 
duplo longioribus. 
Hab. Woodless undulating grass steppes, Lanjoro, Athi plains, 
East Equatorial Africa: J. W. Gregory, April 22, 1893. 
The globose corm is } inch in diameter, with tunics somewhat 
coarsely reticulated upwards. The stiff simple stem, including 
the lax few- (2-4) flowered spike, is 1-14 foot long, and bears 
three linear tapering rigid grass-like leaves with sheathing bases, 
the two lower 10-12 inches long, much longer than the third. 
The herbaceous linear-lanceolate outer valve of the spathe 1s 
2-2} inches long, much shorter than the slender perianth-tube, 
which is 34-4 inches long, and about 3 inch in diameter at the 
throat; the broadly oval white segments are 12-14 inches long ; 
the stamens reach about halfway up the limb. 
Is very near A. laxiflora, Baker, collected by H. H. Johnston 
in 1884 on the slopes of Kilimanjaro at 2000 feet elevation ; but 
differs in its more robust habit, its firm, narrow linear leaves con- 
trasting strongly with the thin, weak, and often limear-lanceolate 
leaves of the Kilimanjaro plant, its more linear outer spathe-valve 
and larger, broadly oval, pure white perianth-segments. Also 
approaches A. gracilis, Pax, from the Zanzibar coast by Mom- 
basa (//ildebrandt) ; but is a larger plant, with longer leaves and 
spathes and a larger flower. It seems, in fact, intermediate 
between the coast plant and the species from Kilimanjaro in form 
as well as in geographical position; the three plants are, however, 
easily distinguishable. 
Note.—A. gracilis, Pax, in Engl. Jahrb. xv. p. 154, antedates 
A. zanzibarica, Baker, in Handbook of Iridee, p. 188; both 
species are described on Hildebrandt’s plant, no. 2015.’
