Information
Small plants up to 15 cm. Rhizome short; roots rather thin with tubers on short lateral branches. Leaves drying yellowish brown, rosulate, sheathing, with distinctly canaliculate petiole, 5–10 cm. long; lamina forming a distinct angle somewhere between 90° and 180° with the petiole so that it is parallel with the soil surface, 10–20cm. long, 1–3 cm. wide, papillose below at least along the midvein, distinct teeth along the margin, leaf-base attenuate, apex obtuse to acute. Peduncle slender, 5–20 cm. long, scabrid to papillate. Inflorescence a lax raceme, 8–20 cm. long, simple or slightly branched at the base with ± pubescent rhachis; floral bracts papillose, 7–18 mm., obovoid, acute. Pedicels articulated in lower half, 5–6 mm. long in flower, up to 12 mm. in fruit, scabrid to pubescent, 2–4-nate at the lower nodes. Perianth white; tepals patent, 5–8 mm. long, 1.5–3 mm. wide, 3-veined. Filaments fusiform, 2–4 mm. long, with scale-like papillae; anthers ± 2 mm. Capsule trigonous, ± 5–7 mm. long, 5–9 mm. wide, with truncate base. Seeds 2 per locule, saucer-shaped, relatively large, 3–3.5 mm. in diameter.

Notes
C. holstii has often been identified as the Guineo-Congolean rain-forest species, C. alismifolium Baker, to which it is obviously related (cf. C. sp. B ). They differ, however, by several traits: C. alismifolium has thicker, tomentose roots, with tubers as thickenings along the main axes, not on lateral branches; the leaves display less dense venation in that species; it has a shorter more erect peduncle, only up to 5 cm. long; the tepals are widest in the upper part, and not ± parallel-sided as in C. holstii; and in particular, the capsules are distinctly stipitate in C. alismifolium, but truncate, without any sign of a stipe, in C. holstii. The two taxa might represent vicariant subspecies of C. alismifolium; more material and more thorough analyses are needed.
