Chromosome Numbers in Compositae, XII: Heliantheae
SMITHSONIAN CONTRIBUTIONS TO BOTANY 0 NCTMBER 52 Chromosome Numbers in Compositae, XII: Heliantheae Harold Robinson, A. Michael Powell, Robert M. King, andJames F. Weedin SMITHSONIAN INSTITUTION PRESS City of Washington 1981 ABSTRACT Robinson, Harold, A. Michael Powell, Robert M. King, and James F. Weedin. Chromosome Numbers in Compositae, XII: Heliantheae. Smithsonian Contri- butions to Botany, number 52, 28 pages, 3 tables, 1981.-Chromosome reports are provided for 145 populations, including first reports for 33 species and three genera, Garcilassa, Riencourtia, and Helianthopsis. Chromosome numbers are arranged according to Robinson’s recently broadened concept of the Heliantheae, with citations for 212 of the ca. 265 genera and 32 of the 35 subtribes. Diverse elements, including the Ambrosieae, typical Heliantheae, most Helenieae, the Tegeteae, and genera such as Arnica from the Senecioneae, are seen to share a specialized cytological history involving polyploid ancestry. The authors disagree with one another regarding the point at which such polyploidy occurred and on whether subtribes lacking higher numbers, such as the Galinsoginae, share the polyploid ancestry. Numerous examples of aneuploid decrease, secondary polyploidy, and some secondary aneuploid decreases are cited. The Marshalliinae are considered remote from other subtribes and close to the Inuleae. Evidence from related tribes favors an ultimate base of X = 10 for the Heliantheae and at least the subfamily As teroideae.

Hybrid Speciation with External Barriers: Encelia
Hybridspeciationwithexternalbarriers: Encelia (Asteraceae:Heliantheae),acasestudy CurtisClarkandGerardJ.Allan BiologicalSciences,CaliforniaStatePolytechnicUniversity,Pomona,andRanchoSantaAnaBotanicGarden Abstract Most well-documented cases of homoploid hybrid speciation follow the recombinational model, in which the new species passes through a period of genetic rearrangement and reduced fertility. An alternate model has been presented, in which external barriers to gene flow prevent genetic swamping of the new species by the parent species. The two documented cases of hybrid speciation in Encelia (E. virginensis and E. asperifolia) appear to follow this model. In both cases, the species of hybrid origin are morphologically intermediate to the parents, and E. virginensis is also similar to artificial F1 hybrids. In both cases, the species of hybrid origin share random amplified polymorphic DNA (RAPD) markers with each of the parent species. A single sampled individual of each species of hybrid origin combines the nrDNA internal transcribed spacer (ITS) sequences of its parents. All North American Encelia species are obligate outcrossers with n = 18 chromosomes, and in cultivation they form fertile hybrids apparently in all combinations. In the natural environment, plants of F1 phenotype are locally common, but backcross progeny are rare, being confined primarily to areas of human disturbance, and there is no evidence of introgression. Progeny tests in one case of natural hybridisation suggested that backcross progeny are eliminated after seed dispersal. This suggests that the F1 phenotype represents a “local optimum” on the selective landscape, and that the selection against backcrosses strongly reduces gene flow between the incipient hybrid species and the parents. Espèciation hybride avec barrières externes: Encelia (Asteraceae: Heliantheae), une étude de cas La plupart des cas bien documentés de l’espèciation homoploïde hybride suivent le modèle recombinaisonal, où l’espèce nouvelle passe par une durée de réarrangement génétique et la fertilité reduite. -

Taxonomic relationships There are seven other species of Encelia in North America plus additional species in South America (JepsonOnline 2010). The genus Encelia is in the large tribe Heliantheae which also contains the native sunflower, Helianthus annuus L. Phylogenetic studies based on DNA show that Enceliopsis and Geraea are closely related genera and that diversification of species of Encelia has been quite recent (Fehlberg & Ranker 2007). Relationships among the various species of Encelia confirmed hypotheses by Clark (1998) based on chemical and morphological traits. Related taxa in region Four species and spontaneous hybrids of Encelia occur in southern California and may overlap with E. farinosa in some part of its range (FNA 2010, JepsonOnline 2010): E. actoni Elmer (in the southern Sierra Nevada, Tehachapi and Western Transverse Ranges, San Gabriel and San Bernardino Mountains, Mojave and Sonoran Deserts, and Desert Mountains; overlaps with E. -
The Type Localities of Plants First Described from New
THE TYPE LOCALITIES OF PLANTS FIRST DESCRIBED FROM NEW MEXICO. tty Paul C. Standley. INTRODUCTION. In the endeavor to settle the application of old names it is often of the greatest advantage to know exactly where the specimens from which a certain species was described were collected. This is dem- onstrated by the difficulty experienced by botanists in determining the proper reference of names based upon plants cultivated in botan- * ical gardens. With specimens from the type locality of a species one can often supplement a scanty type much better than with specimens that are apparently the same, but collected in other localities. When a description is brief and imperfect and no type has been designated, this is often the only method of interpreting the author's meaning. Unfortunately it is only lately that botanists have come to regard the designation of types and type localities as important. The earlier botanical writers did not consider the practice necessary, underesti- mating the possible development of systematic botany. They were accustomed to assign their new species to large and often indefinite areas, such as "the eastern coast of North America," "Canada," ''west of the Mississippi River," and areas of similar extent. As a result, when it has been found afterwards that there existed a group of closely related species not known to the earlier writer, any of which would fill the original description, it. has often been extremely diffi- cult to tell which member of the group was the basis of the proposed name. Even when the early botanists cite a definite locality or region as the source of their specimens it can not always be accepted implicitly as the type locality, because of later changes in the application of geographical names. -
