Six new species of Ruschieae (Aizoaceae) and further notes in Ruschia

Popis výsledku v původním jazyce

We describe six new species of the Ruschieae (Aizoaceae). Astridia parviflora is described from patches of quartz-gravel north of Kleinzee in Namaqualand in the Northern Cape. This collection extends the known distribution of Astridia from the Richtersveld to south of Port Nolloth. Three of the new species of Ruschia can be placed in recognized subgenera: Ruschia variabilis, from near Kleinzee in the Northern Cape, with basally fused, smooth leaves, ternate flowers, (5-) 6 (-8)-locular fruits with closing bodies, is placed in subg. Tumidula; Ruschia pseudocrassa from Bushmanland along the eastern borders of Namaqualand has highly fused leaves with apical teeth and solitary flowers and is placed in subg. Ruschia; Ruschia joubertiniana from fynbos in the Kouga mountains near Joubertinia, in the Eastern Cape has 11- to 12-locular fruits and laterally compressed leaves and is placed in subg. Cymbifolia. Ruschia rupestris, from the Montagu and Ladismith districts in the Western Cape, is unplaced within Ruschia as the fruits (which lack a closing body) do not agree with any of the existing subgenera in Ruschia. This new species is closely allied to Ruschia altigena and R. karrooica, which share the solitary flowers as well as similar leaves and fruits. From shady kloofs between Steytlerville and Uitenhage in the Eastern Cape, we describe Lampranthus umbraticola. The species differs from L. coralliflorus by its smaller flowers and from L. stayneri since its fruits do not close again once opened. In addition, we clarify the identity of Ruschia indurata, a rare and localized endemic on calcretes from Beaufort West, for which we correct an earlier lectotypification. Lastly, we place Ruschia lawsonii, R. aristata and R. knysnana back in Ruschia.
