Dweller in the mist Clivia x nimbicola - natural hybrid in the genus Clivia Artist - Magda Nel (UP) The epithet nimbicola means 'dweller in the mist', and refers to the mist belt habitat in which this hybrid and its putative parents are found. Clivia x nimbicola is intermediate between Clivia caulescens and Clivia miniata with regards to rhizome, leaf, umbel and flower morphology. Flower colour ranges from pastel orange to pastel pink, with green tepal apices in some specimens. Flowering is erratic, occurring all year round, mainly from July through to December, with some specimens flowering twice yearly-February to May. This long flowering period connects the flowering periods of the two putative parents in the Bearded Man Mountain locality, namely October- November in C. miniata and October-December in C. caulescens. The extended flowering period of C. x nimbicola is regarded as further evidence in support of the taxon's hybrid origin. The formal description of C. x nimbicola is also supported by the observation that the hybrid plants bear berries in the wild, thereby inferring fertility and the possibility to maintain populations by means of subsequent breeding among hybrid plants. The holotype of Clivia x nimbicola was collected on the Bearded Man Mountain near Barberton, on the border between South Africa and Swaziland. In this area these natural hybrids are quite common (50 or more individuals) in sympatric stands of C. miniata and C. caulescens. Judging by plant sizes and the height of aerial stems, original hybrids are as old as their putative parents. Toppled plants with long aerial stems, from either parentage of hybrid, freely produce suckers when in contact with the soil. Seedlings, when present, were usually distributed around its putative parent. The natural distribution range of C. x nimbicola is confined to the Barberton Centre of Endemism, the only known region in which the distribution ranges of C. caulescens and C. miniata overlap. & Extracted and edited from Swanevelder, ZH, Truter JT and Van Wyk, AE. 2006.
