Two recently discovered species of Lachenalia from South Africa, Lachenalia barbarae from the Overberg district of the Western Cape and Lachenalia adamii from the Bokkeveld escarpment of the Northern Cape, are described. In addition, details of the rediscovery of two species previously thought to be possibly extinct in the wild, Lachenalia martleyi from the Overberg district in the Western Cape and Lachenalia macgregoriorum from the Bokkeveld plateau in the Northern Cape, are provided, as well as a range extension for the critically endangered Lachenalia moniliformis from the Breede River Valley in the Western Cape.

Newly described are two new species of Spiloxene Salisb.:  S. nana Snijman from the Bokkeveld Escarpment, Northern Cape Province, is a shade-loving plant with narrow, pale green leaves and small, white or rarely cream-coloured flowers; S. pusilla Snijman from the Matsikamma, Gifberg and Pakhuis Mountains. Western Cape Province, resembles S. nana in habit but the yellow- or white-tepalled flowers which are tetramerous or hexamerous have darkly coloured stamens and style and an ovary with a short, solid, narrow prolongation at the apex. Inhabiting rock overhangs formed by quartzitic sandstone sheets, both species are close allies of S. scullyi (Baker) Garside from Namaqualand.

This is the sixth in a series of papers on Lachenalia, towards a revision of the genus. Three new species are described. L. lutea from the southwestern part of the Western Cape, L. cernua from the southern Cape Peninsula and the Worcester Valley of the Western Cape, and L. nardousbergensis from the Bokkeveld Plateau of the Northern Cape, and the Nardousberge and Middelburg Plateaus of the Western Cape.

Three New Species

Three new species of Iridaceae are described from the Bokkeveld and Roggeveld Escarpments.  Ixia amethystina. a member of section Dichone, is endemic to the edge of the Roggeveld Escarpment. It shares an unusual, inclined spike that is nodding in bud with  I. trifolia but is distinguished by its blackish purple (not yellow) anthers, narrower leaves 1.5-2.0 mm wide, medium-textured corm tunics that form a distinct neck at the base of the stem, and short style branches 2.0-2.5 mm long.Moraea marginata. another Roggeveld endemic, is a member of section Polvanthes and florally similar to M. fistulosa and M. monticola but differs in its linear, channelled leaves 5-7 mm wide, with unusual, thickened margins. Romulea singularis. from the edge of the Kobee River Valley in the Bokkeveld Mountains, is a member of section  Ciliatae. It is unique in the genus in its narrowly funnel-shaped, mauve to purple flowers with slender perianth tube 10-11 mm long, and unusually long filaments, 8-9 mm long, inserted in the lower half of the tube.

A New Species

Gladiolus rhodanthus is a new species known from a single population on the summit of the Stettynsberg near Villiersdorp in Western Cape. South Africa The species most closely resembles G. hirsutus and G caryophyllaceus but differs from both in flower shape and markings and in its ecology and reproductive biology. It forms part of a guild of long- tubed, pink-flowered species including  Erica praecox, Pelargonium radiatum and  Watsonia paucifolia which are pollinated by an undescribed long-proboscid fly. Moegistorhynchus sp nov. (Diptera : Nemestrinidae). Gladiolus sekukuniensis is a new species known from three populations south of the Strydpoortberge in Northern Province It closely resembles G. permeahilis subsp  edulis in vegetative features and in flower form, but differs from it in flower colour and in the elongate peri­anth tube. These floral features are apparently adaptations to pollination by long-proboscid flies.

A new phytoptid genus and two new species, Solenocristus karooensis n. g. & n. sp. and S. searsius n. sp. (Phytoptidae, Sierraphytoptinae, Sierraphytoptini), were collected in the Eastern and Western Cape provinces of South Africa, from southern African endemic dicotyledonous trees Schotia afra (Fabaceae) and Searsia lucida (Anacardiaceae) respectively. They are described and illustrated with the aid of conventional light microscopy and low temperature scanning electron microscopy. Females of both new species possess a distinct pregenital plate divided into two parts by a subcuticular medial ridge. Additionally, in S. karooensis n. sp. the movable digit of the male chelicerae varies in length: among six observed males, three males had a movable digit (md) twice shorter than the fixed digit (fd), in one male it was slightly shorter than fd and in the remaining two males md and fd were of the same length. An updated key to the world genera of the tribe Sierraphytoptini is given. The key incorporates data on seven sierraphytoptine genera including three genera (Neoprothrix Reis & Navia, Solenoplatilobus Chetverikov & Craemer and Solenocristus n. g.) which were described since the last generic key of Eriophyoidea by Amrine et al. (2003) was published.

The taxonomy of Acanthopsis is poorly understood, resulting in great difficulties in distinguishing and identifying infrageneric taxa. In this contribution a taxonomic account of the shrublet members of Acanthopsis is provided. Four species are recognized, two of which are newly described, namely A. dregeana and A. erosa (both confined to the Northern Cape Province, South Africa). Acanthopsis trispina, hitherto only known from the orginal collection, is considered a synonym of A. horrida. Acanthopsis spathularis has been recollected after more than 180 years and its status as a distinct species is confirmed. The names A. spathularis and A. horrida are lectotypified here. An identification key to the species of the shrublet group in Acanthopsis is provided.

Trachyandra eriocarpa and T. bulbosa are two new species from Northern and Eastern Cape Provinces of South Africa. They are placed in T. sect. Liriothamnus based on their wiry roots, the cataphylls not forming membranous collars, and the remains of the outer leaves forming a fibrous collar. Trachyandra eriocarpa from the Great Winterberg in Eastern Cape is recognised by its unusual, villous ovary and capsules; and T. bulbosa from north of Springbok in Northern Cape by the irregular, bulbous rhizome, microscopically puberulous leaves and maculate tepals.
