    Note
    S. pseudohumifusa subsp. saxeri Y.B.Harv., from Nigeria and Cameroon, is similar in leafshape, however, it differs from S. glandulibracteata in having prickles, and/or smaller corollas (10–13 mm long), calyces (4.5–5 mm long) and calyx teeth (1–1.5 mm long). Material of this species has previously been determined as S. aculeolata. Specimens were not treated by Björnstad et al. (1971). Similarities shared with S. aculeolata include habit and corolla size and colour. From S. aculeolata var. aculeolata it is quite distinct in lacking prickles and leafshape (oblong-lanceolate as opposed to ovate). Differences between S. glandulibracteata and S. aculeolata var. inermis include leaf-shape (oblong-lanceolate as opposed to ovate), and smaller corolla posterior lip (2.5–5 mm as opposed to 5–7 mm). Altitudinal ranges also differ: var. inermis grows at a much higher altitude (2750–3300 m (excluding Malawi material)) than S. glandulibracteata (1950–2100 m). In the Southern Highlands of Tanzania, where the two species overlap, S. pseudohumifusa subsp. pseudohumifusa is an erect herb that has stems armed with retrorse prickles and strongly appressed leaves which are narrower (less than 1/2 width to length ratio) whereas S. glandulibracteata is a scandent, ascending herb that has no prickles on its stems and erectpatent leaves which are wider (more than 1/2 width to length ratio). In addition to the above characters, S. pseudohumifusa subsp. pseudohumifusa has a white or blue corolla which lacks the purple markings seen in the white to mauve corollas of S. glandulibracteata. From the Zambian S. pseudohumifusa subsp. minutiflora Y.B.Harv., S. glandulibracteata is separated on corolla size, which is much smaller in subsp. minutiflora (5–6 mm long, as opposed to 12–15 mm long). S. glandulibracteata is similar in both leaf-shape and having 4–6-flowered verticils to S. pseudohumifusa. However, S. pseudohumifusa is an erect herb that (mostly) has stems armed with retrorse prickles, whereas S. glandulibracteata is a scandent or ascending herb that has no prickles.
