Fleischmannia microstemon var. paniculata H. Rob. var. nov.

Type.

Brazil, Bahia, Ilhéus, ns área do CEPEC, Plants de 70 cm de altura, flores azuladas, invólucru verde, N.V. Cordão de Ouro, 21.10.1977, T.S. Santos 3151 (holotype CEPEC, isotype US). (Figure 4 ).

? Eupatorium paniculatum Schrad., Ind. Sem. Hort. Acad. Gott. 2. 1832; Linnaea 8, Litt. 26. 1833, hom. illeg., non Miller 1768. Photo from G-DC. Herbarium seen.

With the habit of the typical variety, but differing by the rather abrupt short acuminatie tips on leaf blades, stipitate glands on the peduncles and branches of the inflorescence, and by the not or scarcely paler ribs on the submature achenes.

Paratypes.

Brazil: Bahia, 1842, Glocker no 18 (BM, US); Bahia, forests of the Rio Grongogy Basin, alt. 100-500 m, 1 Oct.-30 Nov. 1915, H.M. Curran 147 (US); Paraiba do Norte, Areias; Escola de Agronomia do Nordeste, herva colluda em logares relativamente umidos, 9-3-1947, J.de Moraes Vase 17 (RB, US); Pernambuco, Tapera, at wet shady border of a thicket, 26 July 1931, D.B. Pickel s.n. (LCU, US).

The variety is evidently restricted to areas near the coast of northestern Brazil. The locality in Bahia and the shape of the leaf blades as seen in the photograph of the G-DC specimen make it almost certain the Schrader nom. illeg. represents this same variety. While there is no nomenclatural requirement for perpetuating the Schrader name it has been decided to do so.
