Plant._ vol. iii. p. 709. =Gladiolus Ludwigii=, _Pappe._ var. calvatus, _Baker Fl. Cap._ vol. vi. p. 150. This _Gladiolus_ belongs to the same section of the genus as _G. Rehmanni_, figured on Plate 20. The variety _calvatus_ has up to the present only been recorded from the Pretoria and Barberton Districts of the Transvaal, but the species is a native of Natal, East Griqualand and the Transkei. The specimens from which our illustration was made were collected by Dr. I. B. Pole Evans, C.M.G., at Brits, and were found growing in deep black turf soil. The variety is also figured in the _Botanical Magazine_, t. 6291, and a comparison of that plate with the one reproduced here will show a difference in the colouring of the flowers, but Dr. Pole Evans states that the pale yellow and speckled forms grow together and are undoubtedly the same. The yellow-flowered form was introduced into cultivation in England in 1877, and both this and our plant differ from the species in being glabrous. DESCRIPTION:--_Plant_ about 1 m. high. _Old corm_ 4 cm. in diameter, 1·5 cm. thick, disc-like; new corm more or less globose on the old corm. _Produced leaves_ about 5, the longest up to almost 1 m. long, the free portion of uppermost leaf about 30 cm. long; all 0·8-1·8 cm. broad, strap-shaped, narrowing to the apex, acute or obtuse, equitant at the base, 12-15-nerved with the main nerves subprominent and with cartilaginous margins, glabrous. _Inflorescence_ densely many-flowered, almost 30 cm. long. _Outer spathe valve_ 3·7 cm. long, 2 cm. broad, ovate, acuminate, acute, 3-keeled below, with membranous margins, glabrous; inner spathe-valve very similar to the outer, but strongly 2-keeled. _Perianth-tube_ 1·5 cm. long, slightly curved; the upper perianth-lobe 4·2 cm. long, 1·8 cm. broad, elliptic, shortly apiculate; two upper lateral lobes 3·5 cm. long, 2 cm. broad, ovate-elliptic, shortly apiculate at the apex; lowermost lobe 3·2 cm. long, 1·3 cm. broad, elliptic-ovate, minutely apiculate; two lower lateral lobes 2·5 cm. long, 6 mm. broad, linear-oblong, apiculate. _Filaments_ 1·2 cm. long, terete, glabrous; anthers 1·25 cm. long, linear, somewhat sagittate at the base. _Style_ 2·5 cm. long, terete, glabrous; stigmas 8 mm. long, linear, broadening to the apex (National Herb. 2731). * * * * * PLATE 125.--Fig. 1, leaf; Fig. 2, portion of leaf showing ribs; Fig. 3, median longitudinal section of flower; Fig. 4, inner spathe-valve; Fig. 5, outer spathe-valve; Fig. 6, cross-section of ovary; Fig. 7, style and stigmas; Fig. 8, stamen.
