Description
Zygophylax geminocarpa Millard, 1958
Zygophylax geminocarpa Millard, 1958: 177–179, fig. 4 d–g; Millard, 1975: 195, fig. 63 d–g; Rees & Vervoort, 1987: 84; Calder & Vervoort, 1998: 28; Vervoort & Watson, 2003: 69.
Type series. Holotype — eight fertile stems in alcohol and two whole mounts (SAM H59) (Millard, 1979).
Type locality. Coll. Pieter Faure, St. 12308, Off Port Shepstone, Natal, South Africa, 30°53’S, 30°28’E, 66 m, 14 March 1901.
Geographical distribution. Only known from type locality.
Remarks. This is the remaining species for southern Africa but, unfortunately, the type and additional materials of this species could not be accessed. Zygophylax geminocarpa Millard (1958) resembles Z. crozetensis in its short hydrothecal pedicel, arrangement of hydrothecae and shape of hydrothecal walls with the abcauline wall almost rectilineous and adcauline wall convex for most of its length, besides of the elongated gonotheca fused to each other for about 3/4 of length, and the similar measurements of the trophosome. Zygophylax geminocarpa was described by Millard (1958) as “Cauline hydrothecae almost completely immersed in the peripheral tubes of the stem. Nematotheca 1–4 on each hydrothecal apophysis (usually 2), and an irregular number on the peripheral tubes of the stem. Gonothecae not collected in coppiniae, but attached to one another in pairs, and arranged in dense clusters around the main stem and principal branches. Each gonotheca very large, elongated, round in section, tapering to the base, and, more rapidly, to the tip, fused to its twin for about 3/4 of length and then free. Scattered nematothecae borne on lower half. The gonothecae are not fully mature and have no openings to the exterior, nor can the sex be determined”.
