(1963: 446); Moldenke (1968: 34); Lebrun &amp; Stork (1997: 526). – Type: Cameroun, Bipinde, am Lokundje-Ufer, 80 m, Apr. 1897, <i>Zenker</i> 1333 (holo-: B †, iso-: Pbarcodes P 00442317, P 00442318 &amp; P 00442319, BM barcode BM 000834558, E barcodes E 00214021 &amp; E 00193458, Gbarcodes G 00023655 &amp; G 00023656, Wbarcode W 1898-0006745, HBG barcode HBG513570, Kbarcode K 000192753, WU barcode WU 0069994, KFTA barcode KFTA 0002112). <i>Vitex vermoesenii</i> De Wild. (De Wildeman 1929a: 16; 1929b: 66) pro parte, excl. syntypes <i>Pynaert</i> 1696 (BR, BM), <i>Sparano</i> 129 (BR), <i>Vermoesen</i> 1733 (BR). – Type: D.R. Congo, Mayombe, Temvo, 6 Mar. 1919, <i>Vermoesen</i> 1742 (lecto-: BR barcode BR 0000008906588, <b>designated here</b>; isolecto-: BR barcode BR 0000008906595, BM barcode BM 001209278), <b>synon. nov</b> <b>.</b> A tree. Twigs almost glabrous except at nodes. Leaves 5–7-foliolate; petiole 10–20 cm, almostglabrous; petiolules 5–25 mm, lamina abruptly contracted into a long fine acumen, upper surface slightly scabrid, lower surface almost glabrous, with many yellow glands, (8–)11–20 pairs of secondary veins. Inflorescence of dichasia, much branched, long pedunculate, multiflorous; calyx 1.5–2 mm, with many yellow glands, corolla c. 4 mm, whitish, with lower lip purplish, ovary glandulose. Fruit 20–30 mm long. <b>Distribution</b> – Wtropical Africa, from Ghana southwards to Angola. <b>Note</b> – Lectotypification of <i>Vitex vermoesenii</i> De Wild. Five syntypes are cited in the protologue (<i>de Briey</i> 55, <i>Pynaert</i> 1696, <i>Sparano</i> 129, <i>Vermoesen</i> 1742, <i>Vermoesen</i> 1933). They are an admixture of two species. <i>Pynaert</i> 1696 (BR barcodes BR0000009861466 &amp; BR0000009861794, BM barcode BM001209279), <i>Sparano</i> 129 (barcode BR0000009862159), and <i>Vermoesen</i> 1933 (barcodes BR0000009862180 &amp; BR0000009861817) are <i>Vitex ferruginea</i> Schumach. &amp; Thonn. On the other hand, <i>de Briey</i> 55 (BR barcodes BR0000009861480 &amp; BR0000009862173) and <i>Vermoesen</i> 1742 (BR barcodes BR0000008906588 &amp; BR0000008906595, BM barcode BM001209278) are <i>Vitex rivularis</i> Gürke. The protologue describes <i>Vitex vermoesenii</i> as having “… calice de env. 1 mm de long, …” and “… inflorescence formant une panicule terminale ample…” “… inflorescences partielles axillaires atteignant 10 cm de diam.; …” (De Wildeman 1929a); all these characters clearly point to <i>Vitex rivularis</i>. <i>Vermoesen</i> 1742 (BR barcode BR0000008906588) is chosen as the lectotype because it has De Wildeman’s handwriting on the label.
