Lychnophora bahiensis Mattfeld (1923: 430) . Type:— BRAZIL. Bahia : caatingazone, 1914, P. von Lützelburg 12460 (holotype: M e! [ M0029464 ]; isotype: B †) .

Distribution and habitat: — Brazil ( Bahia , Minas Gerais, widespread in the Espinhaço Range of mountains). Campo rupestre; 800–1550 m.

Taxonomic notes: —A species best recognized by its lanceolate leaves with acute apices and cordate to auriculate bases, and capitula with 1 to5 florets.It can be confused with Lychnophora gardneri , which differs from L. rosmarinifolia in its leaves with obtuse to slightly rounded apices, attenuate bases and secondary veins obscured by a villous indument on abaxial face. Also similar to L. staavioides and L. pohlii : see these species for a discussion of the differences. Some controversies exist concerning the identity of L. bahiensis , L. rosmarinifolia and L. uniflora . Coile & Jones (1981) suggested a hybrid origin for the two former species ( L. staavioides × L. uniflora ) but that hypothesis was discarded by subsequent authors ( Robinson 1983, Semir 1991, Hind 1995). However, Robinson (1983) and Hind (1995) applied the name L. bahiensis for plants identified here as L. uniflora (following Semir (1991)). The conspecificity of L. bahiensis with L. rosmarinifolia is quite clear upon the distinctive leaf morphology shared by all studied specimens. See comment under L. salicifolia for the publication of the name L. bahiensis in Lützelburg (1922).
