buted, often or very often irregularly confluent, rather numerous, on the back more numerous, a little lighter, nearly whitish, more separate towards the tip, otherwise very confluent, more or less covering the ground colour, often arranged in very indistinct crossbands. Scapes 2-4, always simple, 20-40 cm. long. I have not seen the floweres and the following remarks are taken from the text and figure of Phillips. Sterile bracts 6-8 mm. long. Pedicels 10 mm. long, their bracts 5-6 mm. long. Flower i|cm. long, swollen base longer than the tube, distinctly narrowed at the base, more than 5 mm. across, somewhat curved, red, tube nearly straight, greenish, segments obtuse, only a little spreading.—In young plants the leaves are distichous and their flecks at first somewhat prominent.
Triebneriana v.P. in Fedde, Repert. XLV. (1938) 158. The type of this species was collected by Mrs. S. Blackburn three miles north-east of Calitzdorp ( — Triebner No. 1713), cultivated in the Botanic Garden, Kiel; the photograph was taken by Herr Jacobsen; the species is named in honour of Herr W. Triebner, of Windhoek; it is near Gast. angustifolia (Ait.) Haw., Gast. conspurcata (Salm) Haw. and Gast. obtusifolia
(Salm) Haw., it is easily distinguished from these three species by its ascending-incurved, long-acuminate leaves.—Stem very short. Leaves 15-20 cm. long, 4-5 cm. broad, rarely somewhat narrower, distichous, linguiform, gradually and rather long-deltoid-acuminate towards the tip, acute, mucronate, smooth, dark green, a little shining, the older ones ascending and mostly incurved, more rarely recurved; face a little concave, but flat towards the tip, with an inconspicuous longitudinal middle furrow, back somewhat convex, not keeled; margins above the dilated base somewhat rounded, rather acute towards the tip, smooth or with single tubercles towards the base, towards the tip with a serrulate, light horny border smooth at the very tip; flecks whitish or nearly white, roundish or somewhat oblong, on the face numerous, separate or a few confluent, irregularly distributed, on the back more numerous, more confluent, especially numerous towards the leaf-base, arranged in indistinct crossbands or nearly regularly distributed over the whole back of the leaf. Scape branched, up to more than 1 m. long; pedicels 9-10mm. long, their bracts 1 mm. longer. Flowers 20-22 mm. long; swollen base oblong, a little curved, narrowed at the base, 6 mm. across, red, lighter towards the tip, longer than the slightly curved, whitish tube, which has green stripes; segments short, obtuse, somewhat spreading, light-rose coloured with green central stripes.
