Abstract
HINOJOSA-ESPINOSA, Oscar and VILLASENOR, José Luis. New combinations in Pseudognaphalium (Gnaphalieae-Asteraceae) of Mexico. Bot. sci [online]. 2014, vol.92, n.4, pp.489-491. ISSN 2007-4476.
In a broad sense, Gnaphalium L. is a heterogeneous and polyphyletic genus. Pseudognaphalium Kirp. is one of the many segregated genera from Gnaphalium which have been proposed to obtain subgroups that are better defined and presumably monophyletic. Although most Mexican species of Gnaphalium s.l. have been transferred to Pseudognaphalium, the combinations so far proposed do not include a few Mexican taxa that truly belong in Pseudognaphalium. In this paper, the differences between Gnaphalium s.s. and Pseudognaphalium are briefly addressed, and the transfer of two Mexican species and three varieties from Gnaphalium to Pseudognaphalium are presented.
Keywords : generic segregate; Gnaphalium; Mexican composites; taxonomy.
