Padbruggea maingayi (Baker) Dunn, Bull. Misc. Inform. Kew 1911(4): 198 (1911)

≡ Millettia maingayi Baker, Fl. Brit. India 2: 110 (1879). Type: Singapore, 1867-1868, [Alexander Carroll] Maingay 2757, K000881019 (K, lecto.! designated here; see note below)

≡ Phaseoloides maingayi (Baker) Kuntze, Revis. Gen. Pl. 1: 201 (1891)

Nomenclatural note.

There is a sheet at Kew, K000881019, with two different collections by Maingay. One has two mature pods, a leaflet and a few scraps of stem, the other has several leaflets and bits of stem. There are two labels attached at the bottom of the sheet; one states "Herbarium A.C.Maingay 2757, Singapore, 1867-1868, apparently a climber, no duplicates of this interesting sp.". The other has "Herbarium of the late A.C.Maingay 605, Malaya, distributed at the Royal Gardens, Kew, 1871". There is, however, no indication as to which collection represents Maingay 2757 and which might be Maingay 605. Baker in his protologue mentions "Singapore, Maingay" and described the 15 or more leaflets, rounded at both ends and the oblong, velvety pod traversed with deep longitudinal grooves. Since Baker described both fruit and leaves we have inferred that the left-hand fruiting specimen is Maingay 2757 and thereby have selected it to lectotypify the name.

Dunn (1911: 197) in his key to the species Padbruggea dasyphylla and P. maingayi stated that P. dasyphylla had leaflets with revolute margins and was densely tomentose below whereas P. maingayi did not have leaflets with revolute margins and was nearly glabrous below. Our examination of type material of both species has found that the reverse is the case as indicated in our key to the species.
