Monocarps stipitate, stipes 3-6 mm long, 2-3 mm in diameter; monocarps 1 to 6, 20-79 mm long, 8-10 mm in diameter, moniliform, ellipsoid, apex ellipsoid, pubescent, <b>tuberculate, weakly torulose</b>, color unknown; seeds 1 to 6 per monocarp, ca. 12 mm long, 7-8 mm in diameter, ellipsoid; aril absent. Distribution. A west and central African species with a disjunct distribution between Ivory Coast and Cameroon to Gabon, Central African Republic and the Democratic Republic of the Congo; in Cameroon known from Adamaoua and West regions. Habitat. A rare species in Cameroon known from two collections; in gallery forests in drier regions, swamp forests, in submontane rain forests and old secondary forest. Altitude 700-1000 m a.s.l. Local and common names known in Cameroon. None recorded. Preliminary IUCN conservation status. Vulnerable (VU) (Hoekstra et al. 2021). Uses in Cameroon. None recorded. Notes. <i>Monanthotaxis capea</i> belongs to the <i>M. schweinfurthii</i> complex (for details see Le Thomas 1969b, p. 248, under <i>Enneastemon schweinfurthii</i>). This complex is mainly characterized by the shape of its stamens being enlarged in the upper part, the connective covering the small anthers and a narrow filament. Several species were initially described, then placed as varieties of <i>M. schweinfurthii</i> and finally re-elevated to the rank of species and now includes these species: <i>M. aestuaria</i> P.H.Hoekstra (not in Cameroon), <i>M. barteri</i> (Baill.) Verdc. (not in Cameroon), <i>M. foliosa</i>, <i>M. ochroleuca</i> (Diels) P.H.Hoekstra (not in Cameroon), <i>M. schweinfurthii</i> (Engl. &amp; Diels) Verdc. (not in Cameroon), <i>M. seretii</i> (De Wild.) P.H.Hoekstra (not in Cameroon) following Hoekstra et al. (2021). In the fruiting stage, <i>Monanthotaxis capea</i> is easily distinguished by its monocarps that are strongly tuberculate-rugulose, unique within the <i>Monanthotaxis schweinfurthii</i> complex. Flowering material however is difficult to distinguish from other species of the <i>Monanthotaxis schweinfurthii</i> complex, but may be recognized by the combination of ascending to erect reddish brown hairs on the young foliate branches, cuneate to rounded leaf bases, and 4 to 6 ovules per carpel. Specimens examined. <b>Adamaoua Region</b>: A 4 km au SO de Dir près de Bagodo, 6.42°N, 13.38°E, <i>30 July 1966</i>, <i>Letouzey R.</i> 7570 (P,YA). <b>West Region</b>: Près Kongi (10 km au NO de Kimi bankim sur route Fouman-Banyo), 6.09°N, 11.26°E, <i>27 June 1967</i>, <i>Letouzey R.</i> 8738 (P,YA).
