Information
An erect, ± glabrous, stout, perennial herb, up to 1.8 m. tall. Stems green to greenish brown. Leaves narrow and long, up to 33 cm. long but rarely exceeding 6 cm. broad (usually approximately 7–9 times as long as broad), oblong-lanceolate, often ± parallel sided, apically obtuse, sometimes rounded, basally cuneate; glabrous or with scattered papillae on the undersurface; flat or crispate on the margins. Inflorescence an open, ± stout panicle with long branches. Flowers in fascicles, pendulous. Inner tepals accrescent, dark brown, opaque, elongate-triangular, 3–4 (–5) mm. long, with or without tubercles, usually with an unarmed, obtuse, lanceolate apex but the margins otherwise armed with 56 strongly hooked teeth 1.52 mm. long. Nut trigonous, ovoid, brown, shining, 2.53 × 1.52 mm.

Notes
R. quarrei has been distinguished from R. bequaertii by its having large tubercles on all the inner tepals (rarely only on one), whereas in typical R. bequaertii they are absent or, as it seems, only in a most rudimentary state of development. R. camptodon lies between the two in having a large tubercle on one tepal and smaller ones on the others. Apparently the matter is simply one of the degree of accrescence of the midrib, and when material is very immature it is sometimes impossible to forecast which “ species ” is being handled. It is therefore proposed to sink R. camptodon and R. quarrei into synonymy with R. bequaertii. The tubercled form is perhaps commoner than that wholly without tubercles.  Certain examples from Kilimanjaro (Volkens 676!; Greenway 3860!) have broader leaves, inner tepals 4–5 mm. long, and nuts 2.75–3 mm. long, thus suggesting an approach to R. steudelii Hochst. ex A. Rich. Both have however been determined as R. bequaertii by Rechinger, apart from which the presence in our area of R. steudelii — a dock of Ethiopia, Somaliland, and South Africa — as an isolated occurrence would be rather unlikely. Further collecting on Kilimanjaro, especially in the altitude range 2400–2700 m., is nevertheless desirable. Another example, from Kenya, neighbourhood of Thomson’s Falls, Blain in E.A.H. 10915, has basal leaves 9 cm. broad, inner tepals 6–5 mm. long, and nuts 2.5–3 mm. long, and has much the appearance of R. steudelii. This example may merely represent a large form of R. bequartii, to which, following Rechinger, it is here referred.
