Parkia timoriana (DC.) Merr., Philipp. J. Sci., C 5: 33 (1910). – Inga timoriana DC., Prodr.

2: 442 (1825). – Type: Timor, Anon. s.n. (lectotype G-DC [n.v.], designated by Nielsen Adansonia 19: 340 [1980]).

Parkia roxburghii G.Don, Gen. Hist. 2: 397 (1832). – Type : India, Bot. Gard. Calc., Anon. s.n. (lectotype K [ K000791057 ], designated at the first step by Nielsen, Adansonia 19: 340 [1980] and at the second step here; isolectotype LINN [ LINN-HS 1598.37 ]).

Nielsen (1980) referred to the type of Parkia roxburghii G.Don as ‘Smith in Wallich 5288 B, Calcutta (holo-, K)’, This must refer to a sheet that came from Herb. Hooker. This bears a leaf and a separate inflorescence. The inflorescence is annotated ‘Sir J.E.Smith’ and bears a ticket with ‘Bot. Gard. Calc.’ The leaf has a slip from Wallich’s Numerical List for no. 5288, without indication of which collection (A or B) is represented. Thus it seems probable that there are two specimens on the sheet. Therefore, a second-step lectotypification is made here to restrict the choice to the inflorescence that is probably from the collection represented by a specimen in the Smith Herbarium under 1598.37, which Smith received from Wallich in Calcutta in 1819. It is possible that the leaf on the K sheet comes from this gathering also, but it could be from a separate collection from the Calcutta gardens or indeed from the collection made by De Silva in Silhet.
