    Type
    Type: Congo-Kinshasa, Mt Kahusi, Tshinganda Forest, Pierlot 3334 (BR, holo.)
    Habit
    Evergreen tree 10–15 m high; slash slimy, without exudates.
    Branches
    Flora districts: Ultimate branchlets ± 4 mm thick, dull dark brown, glabrous; axillary buds subwoody, globose, 3 mm diameter, apex with spine 2 mm long; bud scales not seen, soon falling
    Leaves
    Leaves alternate, or, less usually, subopposite; blade elliptic, (10–)15–20 cm long, (4–)6–8.5 cm wide, acumen slender, 1.2–1.8 cm long, base rounded-obtuse, leathery, drying brown, lateral nerves 7 pairs, midrib raised above, upper and lower surfaces with thinly scattered appressed, white, 8-armed stellate hairs, ± 0.2–0.3 mm diameter; petiole terete, longitudinally grooved when dry, 1–7 cm long, 1.5–2 mm thick, slightly swollen at base and apex, glabrous; stipules caducous
    Inflorescences
    Inflorescence borne on leafy stems below the leaves, 1 per stem, racemose, ± 3.5 cm long and wide, often with a branch at base, 6–7-flowered, densely white stellate tomentose, with hairs as on leaves, extending to the outer perianth; bracts caducous; pedicels ± 9 mm, articulated 4 mm from the perianth
    Flowers
    Flower colour not reported, campanulate, ± 13 mm long and wide, divided into 5 very thick, triangular lobes, ± 5 mm long and wide, outer surface with indumentum as inflorescence, inner with the median third appressed stellate-hairy, with bands of hairs extending to the ovary, otherwise glabrous Male flowers not seen Female flowers with indehiscent anthers scattered at base of ovary; ovary oblong in side view, ± 3 mm long, 3.5 mm wide, densely puberulous, carpels 5, stigmas, sessile, flat, fleshy, smooth, appressed to top of carpels, forming a cap ± 1 mm deep, 4 mm wide
    Male
    Male flowers not seen
    Female
    Female flowers with indehiscent anthers scattered at base of ovary; ovary oblong in side view, ± 3 mm long, 3.5 mm wide, densely puberulous, carpels 5, stigmas, sessile, flat, fleshy, smooth, appressed to top of carpels, forming a cap ± 1 mm deep, 4 mm wide
    Fruits
    Fruit with 5 follicles developing, follicles patent, subcylindrical, ± 14 cm long, 3.5 cm wide, including a laterally compressed, slightly twisted rostrum 3 cm long, 1.2 cm deep, 0.7 cm wide, and a 1.5 cm long, 1 cm wide stipe.
    Seeds
    Seeds not seen, but reported red ( Hafashimana 727).
    Ecology
    Evergreen forest; 1350–1550 m
    Conservation
    Although known in E Africa only from the two specimens cited above, C. pierlotii is known from 31 specimens in Congo-Kinshasa where it is confined to the District Lacs Edouard et Kivu between 1200–2000 m altitude (Germain 1962 loc. cit.). The number of specimens known suggests that within its range, it is fairly common so it is here assessed as “least concern”. However, clearance of forest in this area would pose a threat and necessitate reassessment.
    Note
    Ishasha Gorge has been known for decades as a site where many Congolian species have their only locality in the FTEA area. It is remarkable that this species has remained undiscovered there so long.
