Disperis szolc-rogozinskiana Szlach. & Kowalk., Polish Bot. J. 53: 2 (2008).
Description:
Tubers 0.7–1.5 cm long, 0.4–0.7 cm in diameter, ovoid to ellipsoid, woolly. Stem 7–17 cm tall, erect, glabrous. Leaves 2, alternate, 0.7–1.7 cm long, 0.4–1.4 cm wide, sessile, ovate-cordate, subobtuse to acute. Infl orescence 1–2 cm long, 1–3-fl owered. Floral bract 3.5–8.0 mm long, ovate to lanceolate-ovate, acute. Ovary 6–15 mm long, slender cylindrical, erect. Hood 10 mm long and 7 mm wide, obovate in general outline with attenuate base, slightly notched at apex, widest above the middle, strongly arcuate, shallowly concave. Dorsal sepal 9 mm long, 1 mm wide, linear-lanceolate, acute, shorter than petals. Petals 10 mm long, 3.5 mm wide, obliquely obovate, obtuse. Lateral sepals 8 mm long, 4 mm wide, obliquely elliptic-ovate, sub-obtuse, joined together along the basal third of their length, bearing small sacs each, to 1 mm long near the middle at the inner margins. Lip 5.5 mm long in total, claw 3 mm long, linear, bent sharply back near the middle and there with two diverging papillate lobes, 1.7 mm long, 0.5 mm wide, the claw terminating in a limb 2 mm long and 1.5 mm wide, cordate-circular, convex, apiculate, with erose and folded apical margins, bearing a perpendicular, elliptic, papillate keel in the center.
Etymology:
Dedicated to Stanisław Szolc- Rogoziński, a Polish explorer of S Cameroon during 1882–1886.
Notes:
No doubt this species is related to Disperis togoensis Schltr. but is easily distinguishable by having an ovate-cordate, acute lip appendage; by its obovate hood, truncate to notched at the apex, and widest in the upper half. In Disperis togoensis the lip appendage is transversely elliptic, obtuse to notched at the apex; the hood is ovate, acute, with a cordate base, widest in the lower part.
Habitat:
In forests. Flowering in June–July.
Distribution:
Cameroon
