A Nomenclator of Diplostephium (Asteraceae: Astereae): a List of Species with Their Synonyms and Distribution by Country
32 LUNDELLIA DECEMBER, 2011 A NOMENCLATOR OF DIPLOSTEPHIUM (ASTERACEAE: ASTEREAE): A LIST OF SPECIES WITH THEIR SYNONYMS AND DISTRIBUTION BY COUNTRY Oscar M. Vargas Integrative Biology and Plant Resources Center, 1 University Station CO930, The University of Texas, Austin, Texas 78712 U.S.A Author for correspondence ([email protected]) Abstract: Since the description of Diplostephium by Kunth in 1820, more than 200 Diplostephium taxa have been described. In the absence of a recent revision of the genus, a nomenclator of Diplostephium is provided based on an extensive review of the taxonomic literature, herbarium material, and databases. Here, 111 species recognized in the literature are listed along with their reference citations, types, synonyms, subspecific divisions, and distributions by country. In addition, a list of doubtful names and Diplostephium names now considered to be associated with other taxa is provided.

University Avenue, Ann Arbor, Michigan 48109, USA Integrative Biology and Plant Resources Center, The University of Texas at Austin, Austin, Texas 78712, USA ([email protected]) Communicating Editor: Chrissen E. C. Gemmill Abstract—A recent phylogenomic study has shown that Diplostephium in its broad sense is biphyletic. While one of the clades comprises 60 species distributed mainly in the Northern Andes, the clade that contains the generic type, Diplostephium ericoides,contains48species,andprimarilyinhabitsthe Central Andes. Here, I propose to reinstate the generic name Piofontia and transfer to it the species of Diplostephium in the Northern Andean clade. Piofontia consists, then, of 60 species of woody subshrubs, shrubs, and small trees inhabiting high Andean forests and p´aramos of Costa Rica, Colombia, Venezuela, and Ecuador. A morphological description is provided for the genus Piofontia along with a species list with 60 new combinations. Dysaster cajamarcensis is shown to be a synonym of Diplostephium serratifolium. Finally, a brief discussion about the morphological evolution of South American Astereae is provided. Keywords—Andes, South America, p´aramo.

Preliminary Phylogeny of Diplostephium (Asteraceae): Speciation Rate and Character Evolution
NUMBER 15 VARGAS AND MADRIN˜ A´ N: SPECIATION AND CHARACTER EVOLUTION OF DIPLOSTEPHIUM 1 PRELIMINARY PHYLOGENY OF DIPLOSTEPHIUM (ASTERACEAE): SPECIATION RATE AND CHARACTER EVOLUTION Oscar M. Vargas1,2 and Santiago Madrin˜a´n2 1Section of Integrative Biology and the Plant Resources Center, The University of Texas, 205 W 24th St., Stop CO930, Austin, Texas 78712 U.S.A., email: [email protected] 2Laboratorio de Bota´nica y Sistema´tica Universidad de los Andes, Apartado Ae´reo 4976, Bogota´, D. C., Colombia Abstract: Diplostephium comprises 111 neotropical species that live in high elevation habitats from Costa Rica to Chile. Primarily Andean, the genus seems to have undergone an adaptive radiation indicated by its high number of species, broad morphological variation, and diversification primarily in an ecosystem (pa´ramo) that formed within the last 2–5 my. Internal transcriber spacer (ITS) sequences and several chloroplast markers, rpoB, rpoC1, and psbA-trnH were sequenced in order to infer a preliminary phylogeny of the genus. The chloroplast regions showed no significant variation within the genus. New ITS data were therefore analyzed together with published sequences for generating a topology. Results suggest that Diplostephium and other South American genera comprise a polytomy within which a previously described North American clade is nested. Monophyly of Diplostephium was neither supported nor rejected, but the formation of a main crown clade using different methods of analysis suggests that at least a good portion of the genus is monophyletic. A Shimodaira-Hasegawa test comparing the topology obtained and a constrained one forcing Diplostephium to be monophyletic showed no significant difference between them. -
