This species of Gladiolus is here figured for the first time. Rehmann collected it between the Elands River and Klippan, and it was then lost sight of until rediscovered by Dr. I. B. Pole Evans at Nylstroom, Waterberg District, in February, 1917, and has now been established in the Gardens of the Division of Botany, Pretoria. We are indebted to Mrs. Frank Bolus for identification.
DESCRIPTION:--_Corm_ small, 2 cm. in diameter, subglobose, with light brown membranous tunics. _Leaves_ 4-6, basal, 30-60 cm. long, 1·2 cm. broad, linear, glabrous, rigid, with prominent ribs. _Peduncle_, including the inflorescence, 60-65 cm. long. _Spike_ 20-25 cm. long, lax. _Outer spathe-valve_ 7-9 cm. long, oblong-lanceolate, at first bright green, then turning to dark slate-violet (R.C.S.). _Perianth_ white to pale mauve (not red as stated in the _Flora Capensis_); tube curved, 2-2·5 cm. long, funnel-shaped in the upper half; lobes 4-4·5 cm. long, the 3 upper 2-2·3 cm. broad, obovate-spathulate; the 3 lower 1·8 cm. broad, oblong, with yellow-green markings at the throat. _Filaments_ arcuate; anthers purple. _Style_ filiform, with 3 cuneate stigmas.

The species of Pachypodium figured in our illustration was first described by the famous traveller, Carl Thunberg, in the year 1794. Thunberg gathered his plants, on which he based his description, between the Gouritz and Sundays River. The name he gave to the species was _Echites succulenta_. Robert Brown, in 1909, surmised that the plant placed by Thunberg in the genus Echites would most likely constitute a distinct genus, and in 1830 Lindley confirmed this, and founded the genus _Pachypodium_ upon, and gave an excellent figure of, this species of _Pachypodium_ in the _Botanical Register_, at t. 1321, but gave it a new specific name, which is omitted from the _Flora Capensis_.
