Diagnostic
It seems logical to put in synonymy the 2 species Culcasia bequaertii De Wild and Culcasia seretii De Wild, with Culcasia sapinii De Wild; They have a number of characters in common: Prominent loops of the collective vein; filiform petioles and peduncles; short sheath, not surpassing 5 mm; interrupted branching of veinlets inside the mesh. Hepper (l.c., 1967) differentiated Culcasia seretii from Culcasia sapinii based on the length of peduncles and the shape of the fruit. The type of Culcasia sapinii has an obovoid fruit, whereas Hepper indicated spherical; also he indicates a solitary peduncle for this species, with a length of 7 cm, whereas the syntype Mortehan 41 has 2, with a length of 9 - 10 cm (a good character indicated in the diagnosis); The type of Culcasia seretii has an exserted spadix, whereas Hepper indicated included. De Wildeman (l.c.,1922), in his description, brings together the same 3 species, the difference being essentially for him on the arrangement of lateral veins and the sheath length. On the specimens studied, some have the oblique lateral veins (a character of Culcasia ser etii according to De Wildeman), but the sheath does not reach 3.5 cm for some and on the same specimen, one can observe the perpendicular veins on some leaves and oblique on others; Further more it is necessary to note that the sheath is always broader and longer in the leaf axil of a sympodial branch or of an inflorescnce; the same remarks refer to Culcasia sapinii insofar as, on the same specimen, there are leaves of different shapes.
General Description
Plant climbing to 1-2 m above the ground; Anchor roots very short 0.3-2 cm; Stem very slender, ca. 2 mm thick when dry; Internodes 2-6.5 cm; LEAVES : Petioles slender, generally longer than half the blade; Sheath narrow, less than half the petiole; Blade 10-19.5 x 3 -6 cm oblong-elliptic, slightly lanceolate to oblanceolate, sometimes cuneate at base, ± long acuminate at apex, acumen narrow, 0.7-2.5 cm, base of blade decurrent on the petiole; 6-10 pairs of primary lateral veins very prominent, slightly oblique or almost perpendicular to the equally prominent, undulating collective vein; both the pairs of lower basal veins ascending to the apex; Dense, slightly prominent network of secondary veins and veinlets, the veinlets often stopping in the mesh in a tapering point; Translucent glandular dashes rather numerous, but hard to see on older dry leaves; On the lower surface of the blade, sparse annular excressences, situated often at the edge or on a vein or veinlet. INFLORESCENCES axillary, 1-2; Peduncles slender like the petioles, 7-11 cm, generally equal or longer than the petioles from which they are borne; Spathe green, 2.5-3.5 cm, mucronate; Spadix white or cream, sometimes exserted, terminating in the male flowering axis in fruit, stipe ca. 7 mm; Ovary subglobose, unilocular, uniovulate; Placenta parietal; Stigma striate radially. INFRUCTESCENCE : Berries obovoid, 10-15 x 6 - 8 mm, red.
Habitat
In the understorey of secondary forest or a the edge of water courses.
Distribution
Western and Central Africa, but unknown occuring in Congo. In Cameroon, more frequent in the aest, in the regions of Bertoua, Batouri, Lomié, Moloundou and to a lesser degree in the regions of Sangmélima, Oveng, Kribi, Yabassi, Douala, Mbanga.
