The tribe Senecioneae (Asteraceae: Asteroideae) has recently been reclassified as a result of molecular phylogenetic investigations, and species with succulent leaves have been identified in several different clades of the tribe. We study the leaf morphology and anatomy of 20 selected species of Senecio s.l., embracing representatives of all distinct groups of leaf succulents in Senecioneae, and contrast the results with a molecular phylogeny derived from ITS sequence data. The leaves of the studied species vary as to their gross appearance (flat to terete, horizontally or seemingly vertically oriented, with or without ‘window’ areas) as well as with respect to their macro-anatomy (tissue succulence vs. all-cell succulence). The morphological and anatomical characterizations of identified groups correlate well with the clades found in the ITS-based molecular phylogenetic studies, and the reclassification of succulent-leaved species of Senecio s.l. into the segregate genera Caputia, Kleinia and Curio is strongly supported. Leaf characters provide easy-to-observe diagnostic characters to recognize the three genera.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"347 1","pages":"11 - 26"},"PeriodicalIF":1.5,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76390160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The monophyletic genus Grusonia illustrates how the instability in the generic concept for this group of species has produced a disproportionate increase in names. This large increase in the number of names is due mainly to treatments presenting new combinations at the generic level without any significant reduction in the number of species through synonymy, and shows the uncoupling of the generation of new names from the publication of new species. Three historical nomenclatural phases in Grusonia are identified showing that the majority of the new names were proposed before any molecular phylogenetic reconstruction had an impact on the systematics of the group. However, molecular systematics has played an important role for the delimitation of a monophyletic genus. The lack of a solid phylogenetic hypothesis of relationships was one factor that promoted the superabundance of homotypic synonyms for these 17 species of North American grusonioids. In the face of this phenomenon, which we refer to as nomenclatural proliferation, the subgeneric categories in the subfamily Opuntioideae are historically devalued.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"10 1","pages":"27 - 34"},"PeriodicalIF":1.5,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82213545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salm-Dyck. This species and its wild congeners inhabit dry and subhumid tropical and subtropical regions in western and eastern Mexico down to Panama. In Mexico, its tender, young cladodes (known locally as nopalitos) and flower buds (tunitas) are eaten as vegetables, its developed cladodes are used as forage in different parts of the world, and the plants are used as living fences and also as ornamentals. The fruits of N. cochenillifera have received little attention in the specialized literature; therefore, the purpose of this note is to describe a set of fruits that was bought in a traditional market in San Luis Potosí, México. The fruits of N. cochenillifera were, on average, two centimeters shorter than those reported in the literature; by weight, the pulp accounted for 45.70 % on average, the peel 48.07 % and the seeds 6.23 %. Mean sweetness was 10.62 oBrix, somewhat lower than that of Opuntia cultivars, which is 12.95. Due to the lack of abortive seeds, we infer that the fruit of Nopalea have been of little interest to humans.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"68 1","pages":"43 - 45"},"PeriodicalIF":1.5,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84096919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
