“The new species Pelargonium elandsmontanum is a local endemic from Elandsberg Nature Reserve near Malmesbury in the Western Cape Province, South Africa. One of six species of sect. Hoarea with just the posterior two petals developed, it resembles P. ternifolium in its trifoliolate leaves and pink petals but is distinguished from that species by the short, stout petioles, rhombic, acute leaflets with the upper surface glabrous or with spreading hairs (vs cuneate, apically incised leaflets with both surfaces adpressed-hairy), and five (vs four) fertile stamens.” J.C.
