03BE5F3C6F2CD23B3556FD7AFA89AA15.taxon	diagnosis	Diagnosis – Streptocarpus malachiticola differs from S. goetzei in the glandular-pubescent pedicel with shorter eglandular hairs intermixed, the glandular-pubescent calyx, the smaller corolla with glandular hairs outside, the glandular-pubescent ovary, the bilobed stigma and the distinctly shorter capsule. The upper lip of the corolla bears strongly divaricate lobes, thus also differing from S. goetzei. It differs from S. compressus in the strictly unifoliate habit, the glandular-pubescent calyx, the shorter lower lip of the corolla, the blue-violet corolla with pale-whitish palate, the shape of the upper lobes and the more strongly constricted mouth, the eglandular style and the shorter capsules.	en	Fischer, Eberhard, Darbyshire, Iain (2021): Five new species of Streptocarpus (Gesneriaceae) from Katanga, D.

03BE5F3C6F2CD23B3556FD7AFA89AA15.taxon	discussion	Taxonomic notes – The species is clearly related to Streptocarpus goetzei Engl. (Engler 1901: 406) and S. compressus B. L. Burtt (Burtt 1958: 570) which also bear a corolla mouth compressed between the upper lobes so that the opening is shaped like an inverted V (Hilliard & Burtt 1971). The three species are compared in table 1. Streptocarpus goetzei is usually confined to forests and is found in southwestern Tanzania (Rungwe Mts), southern Malawi, and northern Mozambique (Hilliard & Burtt 1971; Darbyshire 2006). The new species is endemic to metalliferous rocks in Katanga (Duvigneaud & Denaeyer-De Smet 1963). It is probably more closely related to S. compressus which is confined to Songea and Iringa Districts in Tanzania, where it grows in open rocky habitats (Hilliard & Burtt 1971; Darbyshire 2006). Streptocarpus malachiticola is already figured by Malaisse et al. (2016) under the name of Streptocarpus aff. michelmorei B. L. Burtt. A photograph is published on the website http: // copperflora. org / eflora / index. php? family = Gesneriaceae under the name of Streptocarpus rhodesianus.	en	Fischer, Eberhard, Darbyshire, Iain (2021): Five new species of Streptocarpus (Gesneriaceae) from Katanga, D.

With an estimated AOO of 12 km 2 (assuming a 4 km 2 grid cell size) and four herbarium specimens from three locations, the most recent being collected in 1990, the species could be preliminarily assessed as Endangered: EN B 1 + 2 ab (iii).	en	Fischer, Eberhard, Darbyshire, Iain (2021): Five new species of Streptocarpus (Gesneriaceae) from Katanga, D.

03BE5F3C6F21D230367CFF2FFE33ADDB.taxon	discussion	Taxonomic notes – Streptocarpus bampsii, S. malaissei, S. salesianorum, and S. schaijesii are morphologically close and apparently related to Streptocarpus michelmorei B. L. Burtt (Burtt 1939: 72) and S. solenanthus Mansfeld (Mansfeld 1934: 96) in Streptocarpus agg. cooperi of Hilliard & Burtt (1971). They have eglandular hairs on the pedicel, calyx, and corolla, and the limb is small in relation to the tube, with a lower lip not exceeding 15 mm of length. Hilliard & Burtt (1971) assigned some taxa to the S. michelmorei complex, where they distinguished two species from Malawi (7 A Streptocarpus sp. S. michelmorei affinis) and Zambia (7 B Streptocarpus sp. S. michelmorei affinis). Despite the overall similarities, several distinct entities can be distinguished which are described here as new species. One taxon from this aggregate, Streptocarpus mbeyensis I. Darbysh. (Darbyshire 2006: 39) has already been described. For a comparison of the species see table 2. Wild-collected material assigned to S. michelmorei appears to be rather more variable than the type material. Hilliard & Burtt (1988) suggests that plants from Bridal Veils Falls in the Chimanimani Mts of Zimbabwe (e. g. Bamps, Symoens & Vandenberghen 770, BR 0000016801868, BR 0000027611722 V) may be intermediate between S. michelmorei and S eylesii S. Moore, stating that the deep corolla colouration and slender fruits are close to S. michelmorei but that the distinctly curved corolla tube and larger median lobe suggest the influence of S. eylesii. However, the Bridal Veils Falls plants have a short eglandular indumentum on the inflorescence, whilst both S. michelmorei and S. eylesii usually have a glandular component to their inflorescence indumentum, casting doubt over Burtt’s theory that this is a hybrid population.	en	Fischer, Eberhard, Darbyshire, Iain (2021): Five new species of Streptocarpus (Gesneriaceae) from Katanga, D.
