description: 2. <i>Drosera bequaertii</i> Taton — Fig. 4 <i>Drosera bequaertii</i> Taton (1945a) 308;G.C.C. Gilbert (1951) 553;J.R. Laundon (1970) 27; (1978) 64; A.S.Rob. et al. (2017) 1334. <i>—</i> Type: <i>J. Bequaert 476</i> (holo BR), DRC, 8 June 1912. <i>Drosera compacta</i> Exell &amp; J.R.Laundon (1955a) 44. — Type: <i>A.W. Exell &amp; F.A. Mendon ҫa 1030</i> (holo COI), Angola, Lunda Sul, Rio Luachimo, entre Sila Henrique de Carvalho e Dala, ‘Tenga’, 24 Apr. 1937. Perennial herb, shortly caulescent. <i>Stems</i> 3–4 (up to 7) cm long, 1–2.5 mm diam, densely pilose (Fig. 4b). <i>Leaves</i> alternate, clustered at the apex and erect, basally more widely spaced and more or less reflexed; stipules 2–4.5 mm long, membra- nous, ferrugineous, lacerated at the apex; lamina obovate to spathulate, 4–12 by 3–6 mm, the adaxial surface and margins bearing tentacles, abaxially pilose (Fig. 4a); petiole 5–12 by 0.5–1 mm, flat, densely pilose. <i>Inflorescence</i> cymose, with 2–8 flowers; peduncles 1 or 2 together, 10–17 cm long, completely erect, basally glandular and pilose to densely pilose, apically glandular; bracts almost linear, 2–3 mm long, glandular or pi- lose; pedicels 2–7 mm long, glandular. <i>Sepals</i> 5, lanceolate to ovate, 3–4.5 by 1.5–2 mm, connate at the base, occasionally apex serrate, glandular. <i>Petals</i> 5, obovate, 5–7 by c. 4 mm, bright pink. <i>Stamens</i> 5, filaments 3–4 mm long. <i>Pistil</i>: ovary subglobose, 2–3 mm diam, glabrous; styles 3, c. 2 mm long, bipartite to the base, branches ascending, with broadened apices. <i>Seeds</i> suborbicular to ovoid, c. 0.3 by 0.2 mm (Fig. 4e), black, shining, testa smooth. Distribution — Angola, DRC, Zambia (Fig. 4c). Habitat &amp; Ecology — Grassy wetlands, upland plateaus. <i>Additional specimens</i> (see Fig. 4d for province map). ANGOLA, <i>Moxico</i>, Cameia National Park, Biodiversity Observatory, S11°31' E20°55', alt. 1126 m, 3 May 2016, <i>M.Finckh &amp; Zigelski 143303</i> (HBG). – DRC, <i>Haut-Katanga</i>, Cuv. de Kabiashia, rivière Kandale, alt. 1000 m, 24 June 1968, <i>J. Leonard 4617</i> (BR). Note — <i>Drosera compacta</i> is widely accepted as a synonym of <i>D. bequaertii</i>. Both type specimens show many similarities but differ in leaf arrangement (densely vs more openly arranged) and scape indumentum (basally densely pilose vs glandular and pilose). Since this species is only infrequently documented (Robinson et al. 2017) and only few specimens were studied, no comment can be made on separating both taxa. Here, a more detailed analysis is required.
