Parkia panurensis Benth. ex H. C. Hopkins

2. Parkia panurensis Benth. ex H. C. Hopkins View in CoL in Brittonia 34: 347. 1982. – Holotype: Brazil, [Amazonas], Rio Uaupés, [nr Panuré], Feb 1853 (lv., fl. & imm. fr.), R. Spruce 2727 (K [ K000504617 ]!; possible isotypes, or else paratypes: BM [ BM000952313 ]!, BR [ BR000000520273 ] image!, K [ K000504618 ]!, P [ P02436133 , P02777904 ]!, W [herbarium no. 110500] image!).

Note — Hopkins (1982) stated that the holotype at K and had both flowers and immature fruits, with the date February 1853. Although there are two sheets of Spruce 2727 at K, only the one now with the barcode K000504617 has both reproductive stages plus this date, and so the holotype designation is unambiguous and lectotypification is not required. The handwritten label on the holotype states: “2727 In ripis fluv. Uaupés. Feb/53. (Specms brought me from a tree said to grow in gapó [sic]. Sterile stamens palish red, fertile dull yellow. Parkia ” and the sheet has a stamp for Herbarium Benthamianum with the date 1854. The second sheet, K000504618, is stamped Herbarium Hookerianum 1867, it has leaves and flowers, the locality “Prope Panuré ad Rio Uaupés” and the date “ Oct. 1852 – Jan. 1853 ”. This locality and date range are indicated on the other sheets cited above as possible isotypes. They are all sufficiently similar that they could belong to a single gathering, but it is not possible to be certain, nor can we be sure whether the holotype and these other sheets also comprise a single gathering. If Spruce was using 2727 as a species number, rather than a collection number, the sheets additional to the holotype could be paratypes, rather than isotypes. According to Rolfe (1896), the type of Vanilla sprucei Rolfe also has the collection number Spruce 2727.
