03D1532200501E4AFC8C5774FDBAFD51.taxon	discussion	Notes – Lectotypification of Vitex congolensis De Wild. The protologue cited only one collection (Dewèvre s. n.). The material stored at BR comprise Dewèvre 770 a (2 sheets) and Dewèvre 926 a (3 sheets); one sheet has locality description and notes handwritten by De Wildeman (BR 0000008905918); it is here chosen as the lectotype. Remaining syntypes: sine loco, sine dato, Dewèvre 926 a (BR barcodes BR 0000008905406 & BR 0000008905413). Lectotypification of Vitex thonneri De Wild. The protologue cited Thonner 263, which has been widely distributed to several herbaria. Of the three sheets in BR, the one with De Wildeman’s handwriting on the label is selected as the lectotype. The original material has the diagnostic characters of V. congolensis; it is unusual in having short leaflets, but this trait is variable within the species and Ido not think this variant is worth taxonomic recognition. Lectotypification of Vitex gilletii De Wild. Only one of the two syntypes has been found (Gillet 2163); the other syntype (Pogge 698) has probably been destroyed in Berlin and no duplicate could be traced. The type material of V. gilletii has leaflets with a somewhat unusual shape (low length / width ratio), abruptly contracted in a relatively long acumen. However, V. congolensis has a variable leaflet shape and size and it is impossible to discriminate taxa on that basis.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

03D1532200551E4AFFA65347FDFEF89E.taxon	discussion	Note – Vitex congolensis is a Guineo-Congolian linking species extremely variable as to density, length and intensity of the fulvous color of the indumentum. Variation of indumentum is continuous and cannot be translated into infraspecific units. Vitex thomasii De Wild. is a variant showing a very unusual character, i. e. foliaceous bracts at the lower inflorescence nodes, up to 30 × 8 mm. This is not a teratological condition, because several gatherings from distant localities exhibit such bracts. This variant deserves taxonomic recognition at varietal rank. The type specimen of V. buchneri has not been found. However, the protologue clearly indicates that this taxon belongs here (“ … die Bracteen der Nebenachsen erster Ordnung lanzettlich in den Stiel verschmälert, mit dem Stiel bis 3 cm lang … ”) (Gürke 1893).	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

03D1532200551E4AFFA65706FADDFAD6.taxon	discussion	Notes – Vitex cuspidata Hiern is known from very few collections mostly from Angola, all of them in fruit (Cabral 2013). Pubescence of ovary is unknown and, accordingly, the species keys out in two groups in the key. Material from the Sudanian region has also been ascribed to that taxon (Aubréville 1950: 500) but it is certainly not conspecific. The type material of Vitex kapirensis is a good match of the type material of Vitex cuspidata, with a large inflorescence, relatively small fruits, long-petiolulate elliptic leaflets contracted into a short acumen. V. kapirensis was synonymized (Meerts 2016) with V. fischeri, but the latter has much larger leaflets and tertiary veins forming a more conspicuous ladder pattern.

03D1532200551E4BFCD5553EFE00FC3D.taxon	discussion	Note – V. discoideoglandulosa is a member of the complex of V. thyrsiflora-V. buchananii, characterised by a thyrsoid inflorescence, more or less lianescent habit and small globose fruits (section Terminales W. Piep.). Pieper (1928) regarded it as a synonym of V. volkensii Gürke, an East African plant now synonymized with V. buchananii. However, V. discoideoglandulosa lacks the diagnostic trait of V. buchananii, i. e. the golden-yellow glandulose outer fruit layer exfoliating at maturity. It is undoubtedly a distinct species. Table 1 summarizes the differences between the three species. Lectotypification of Vitex discoideoglandulosa De Wild. De Wildeman (1929 a) cited six syntypes (Claessens s. n., Gillet 1973, Gillet s. n. (coll. 1901), Gillet s. n. (coll. 1902), Gillet s. n. (coll. 1926), Sapin s. n.), corresponding to six sheets in BR. The only specimen with fruits is selected as the lectotype, because the characters of the fruits are discriminant with respect to V. buchananii.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

03D1532200541E4BFF5153AFFDBBF92F.taxon	discussion	Note – V. djumaensis is related to Vitex doniana (glabrous leaves, petiolulate leaflets, pubescent ovary). It has an original combination of traits, i. e. ternate leaves, leaflets with few secondary veins (6 – 10 pairs), small fruit, and ciliate domatia. Vitex djumaensis is endemic to southern D. R Congo. It is a poorly known taxon. All the specimens cited by Moldenke (1955 b) are misidentifications. New specimens have been found, from Bas-Congo, Kasaï and W Katanga, which had been previously misidentified as V. doniana.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

In particular, this author does not appear to have examined pubescence pattern of leaf upper surface and ovary. Idid find two consistent differences between specimens from dense forests and from dry woodlands. The former has persistently puberulent leaf upper surface and ovary crowned by short stiff hairs, while the latter has glabrous leaf upper upper surface and ovary with glands (occasionally a few hairs) at top. These differences justify recognition of V. keniensis at varietal rank; the subspecific rank does not seem appropriate because the area of this taxon broadly overlaps with that of the type variety.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

03D1532200561E49FF515439FA44F9E6.taxon	discussion	Notes – Vitex madiensis subsp. madiensis is probably the most polymorphic Vitex taxon in Africa. Many morphotypes have received a formal taxonomic treatment; some of them have been reported in D. R. Congo by Moldenke (1956): V. madiensis var. schweinfurthii (Gürke) W. Piep. (5 leaflets; e. g. de Bergyck 34, Robyns 3018), V. madiensis var. baumii W. Piep. (leaflet margin entire; e. g. Lebrun 6748), V. madiensis var. glaberrima (glabrous in all parts; e. g. Pittery 819). These taxa are not recognized here. The distribution ranges of V. madiensis subsp. madiensis and subsp. milanjiensis overlap broadly in southern D. R. Congo. Specimens with more or less intermediate characters, possibly of hybrid origin, are occasionally found, especially in savannas of Bas-Congo (e. g. Duvigneaud 252 Vi). Lectotypification of Vitex camporum Büttn. Vitex camporum is based on three syntypes which have all been destroyed in Berlin (Büttner 427 & 428; Welwitsch 5728). Two duplicates of Welwitsch 5728 have been found in BM, and one duplicate of Büttner 427 has been found in K (K barcode K 001008451); all the duplicates match the description in the protologue. Welwitsch 5728 is a better specimen and one of the two sheets is thus selected as the lectotype. Lectotypification of Vitex camporum var. longipedicellata De Wild. De Wildeman cites one collection from Kwamouth by E. & M. Laurent, s. n., which corresponds to two sheets in BR. The sheet with collecting data on the label is chosen as the lectotype. Lectotypification of Vitex schweinfurthii Gürke. The protologue cites two collections i. e. Schweinfurth 2030 & 2848. These specimens have been destroyed in Berlin. Aduplicate of Schweinfurth 2030 matching the description in the protologue exists in K, and is here selected as the lectotype.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.

03D1532200561E46FC8C56CEFA49FEB3.taxon	discussion	Notes – Dwarf, geofrutescent forms of V. madiensis subsp. milanjiensis occur throughout the distribution range of subsp. milanjiensis. They have been repeatedly described as V. hockii De Wild., V. ringoetii De Wild., V. epidictyodes W. Piep., V. caespitosa Exell. Such forms pose two different taxonomic problems. First, it is unclear if they are genetically fixed or if, alternatively, they represent pyrophytic forms induced by burning; Verdcourt (1992) favoured the former hypothesis. Secondly, assuming it is genetically fixed, it is not clear if that morph is monophyletic or, alternatively, if it has evolved several times independently in response to selection by fire or other environmental constraints. Ihave not been able to find differences between dwarf and tall morphs except size. Lectotypification of Vitex epidictyodes Mildbr. ex W. Piep. Three syntypes are cited in the protologue (Stolz 556; Stolz 1478; Trotha 95). Pieper (1929) designated Stolz 556 as the lectotype (see Verdcourt 1992). Many specimens of that gathering have been distributed and Pieper (1929) did not indicate a specific herbarium; therefore second-step lectotypification is necessary (art 9.17 of ICN; McNeill et al. 2012). Since Pieper worked in Berlin, Itherefore select the specimen kept in Berlin as the lectotype. Lectotypification of Vitex grisea Baker. The specimen of Welwitsch 5759 deposited in Kis chosen as the lectotype for two reasons. First it shows better the acute leaflet tips mentioned in the protologue; secondly, Baker worked at Kew Botanic Gardens after Welwitsch’s collections were split and, therefore, almost certainly used the duplicates deposited in K. This morphotype is a somewhat extreme variant in the phenetic variation space of the polymorphic Vitex madiensis subsp. milanjiensis not deserving formal taxonomic recognition.	en	Meerts, Pierre (2018): Synopsis of the genus Vitex (Lamiaceae) in the Democratic Republic of the Congo.
