DESCRIPTION:--_Corm_ ellipsoid, 3 cm. long, 1·5 cm. in diameter, covered
with fine reticulated sheaths. _Leaves_ 7 in a basal distichous rosette,
8 to 11 cm. long, 0·7 to 1·4 cm. broad, linear-oblong, very acute, with
1 more or less evident mid-rib, but many-veined when viewed in
transmitted light. _Peduncle_ about 12 cm. long, flexuose, bearing about
6 distant flowers. _Outer spathe-valves_ 1 cm. long, deeply 3-partite,
inner 2-partite. _Perianth_ distinctly 2-lipped; tube 1·5 cm. long,
widening upwards; posterior segment 2·5 cm. long, erect, clawed, with an
ovate obtuse limb; side-segments 1·7 cm. long, 6 mm. broad, more or less
oblong, obtuse, spreading-reflexed; 3 anterior segments more or less
horizontal and forming a distinct lip. _Style_ as long as the stamens,
divided into 3 lobes dilated at the apex. (National Herb. Pretoria, No.

This charming little _Gladiolus_ was first found by Conrath at Irene,
near Pretoria, and was again collected by Dr. I. B. Pole Evans, C.M.G.,
in the same locality. It was described by Baker, with several other
Transvaal species, in 1904, but is here figured for the first time.
The plant produces a single erect flowering stem with clasping leaves
scarcely produced above. The species belongs to the Section _Hebea_,
which we have illustrated on Plates 63 and 165 (_G. alatus_, _G.
orchidiflorus_), and is closely related to _G. permeabilis_, a species
common in the Cape Province, but which also extends into Bechuanaland.
It is, however, easily distinguished from this species by the
non-produced leaves and hairy stems.
Our illustration was made from the specimens collected by Dr. I. B. Pole
Evans, C.M.G., at Irene.
DESCRIPTION:--_Bulb_ 2 cm. in diameter, globose, covered with brown
fibres. _Stem_ pilose on the lower half. _Leaves_ clasping the stem,
sheath pilose, hardly produced. _Inflorescence_ 13 cm. long, 7-to
10-flowered. _Outer spathe-valves_ 1·5 cm. long, somewhat membranous
above, entire, bifid or trifid; inner spathe-valves similar to the
outer, bifid. _Stamens_ shorter than the style; anthers somewhat
sagittate at the base. _Style-branches_ cuneate, fimbriate on the
edges.

section of flower; Fig. 3, outer spathe-valve; Fig. 4, inner
spathe-valve; Fig. 5, anther; Fig. 6, portion of style with style
branches.
