Type: Kenya, Fort Hall District: Thika, R.E. & Th.C.E. Fries 4 (UPS, holo.; S!, iso.)
Morphology General Habit
Perennial herb, basal part of stems creeping and rooting, apical part ascending, up to 25 cm tall; young stems not conspicuously swollen below nodes, finely sericeous to puberulous
Morphology Leaves
Leaves sometimes variegated along midrib; petiole 0.5–5.5 cm long; lamina abruptly narrowed below middle (lyrate), lower part often sinuate, upper part ovate, largest 5–14.5(–16) × 2–5.5 cm, apex subacute to rounded, not concave below tip; apical part entire (rarely sinuate); with 5–7 main lateral veins each side, subglabrous to puberulous, densest on veins
Morphology Reproductive morphology Inflorescences
Spikes 1–3 cm long; peduncle 5–17 cm long, puberulous and with long pilose hairs; fertile bracts elliptic to obovate in outline, 8–12 mm long, purplish tinged towards apex, puberulous and pilose or densely so, conspicuously ciliate, veins as in C tridentata, deeply 3-lobed (lowermost pair often entire), lobes narrowly triangular, acute to acuminate; bracteoles 3–6 mm long, ciliate towards tip
Morphology Reproductive morphology Flowers Calyx
Calyx as in C. tridentata, longest lobe 4–7 mm long
Morphology Reproductive morphology Flowers Corolla
Corolla pale lilac with yellow throat; tube 9–12 mm long, narrowed above insertion of stamens; limb 10–15 mm long
Morphology Reproductive morphology Fruits
Capsule 7–10 mm long, hairy at apex
Morphology Reproductive morphology Seeds
Seed ± 3 × 3 mm.
Ecology
Dry lowland and medium altitude Drypetes-Syzygium and Croton megalocarpus forest, riverine Newtonia-Filicium forest; 900–1600 m
Note
Polhill & Verdcourt 316 from Meru Forest ( K 4) is somewhat intermediate between this species and C. tridentata. It has less lyrate leaves than typical C. friesiorum and is much less hairy. It is from a wetter forest type than the rest of the material of this species, and is probably no more than an extreme shade form. The area where it was collected is however isolated from the rest of the range of C. friesiorum, and further collections from the Meru area are needed to clarify its status.
