Flemingia paniculata Wall. ex Benth. (1852: 245)

Do, Truong Van, Xu, Bo & Gao, Xin-Fen, 2018, New synonyms, lectotypifications and taxonomical notes on the genus Flemingia (Phaseoleae, Papilionoideae, Leguminosae) from Thai-Indochinese floristic region, Phytotaxa 351 (1), pp. 41-52 : 47-52

Flemingia paniculata Wall. ex Benth. (1852: 245) . Type:— MYANMAR. Ataran river, Wall.Cat. 5759 (holotype K-

001122037!, isotype BM-000958663!)

Flemingia sarmentosa Craib (1927: 69) . Type:— THAILAND. Maharat, elev. 360 m, 15 February 1912, A.F.G. Kerr 2380 (holotype ABD!, isotype BM-000958670!) syn. nov.

Note: — Wallich (1831) originally enumerated F. paniculata in A Numerical List of Dried Specimens based on the specimen number Wall.Cat. 5759, collected from Ataran river, Myanmar ( Figure 5 ), but without a description of the species. Thus, F. paniculata was illegitimate. Later, Miquel (1852) not only validated this name with a full description of the species, but also annotated that F. paniculata is most similar to F. strobilifera by sharing an unifoliolate leaves and clearly distinguished by inflorescence differences. Nearly one century later, Craib (1927) described F. sarmentosa as a new species on the basis of the specimen A.F.G. Kerr 2380 collected from Thailand ( Figure 6 ). The author also mentioned that the species is most similar to F. paniculata by sharing a simple leaf and a racemose inflorescence with flower not enclosed by large folded bracts, but the latter is only distinct from the former by the difference of calyx length. However, our recent examination of protologues and type specimens of these two species showed the calyx length of F. sarmentosa is variable during its flower lifespan and not clearly different from F. paniculata . Furthermore, other morphological characters of F. sarmentosa are mostly identical to those found in F. paniculata ( Table 2). Hence, the former is conspecific with the latter, and is treated here as a new synonym of the latter.

Flemingia sootepensis Craib (1911: 43) . Lectotype (designated here):— THAILAND. Chieng Mai : Doi Sootep, 16 January 1910, A.F.G. Kerr 934 (BM-000958671!, isolectotypes BM-000958672!, E-00157794!, P-00709078!); 1 January 1905, C.C. Hosseus 309 (syntypes P-00709079!, M-0168856 !).

Note: —When Craib (1911) described this species from Doi Sootep, Chieng Mai, Thailand, he cited two specimens in the protologue, e.i. A.F.G. Kerr 934 at E (E-00157794), BM (BM-000958671, BM-000958672), P (P-00709078) ( Figure 7 ) and C.C. Hosseus 309 at P (P-00709079), M (M-0168856) ( Figure 8 ), without designating the holotype. A search of these syntypes at relevant herbaria revealed that the specimen A.F.G. Kerr 934 at E (E-00157794) has complete branches of open flowers and mature fruits, which match very well with the diagnostic characters of the species mentioned in the protologue, and selected here as the lectotype of the species ( Figure 7 ). The remaining duplicates at BM and P are designated here as the isolectotype.
