Its representatives are very succulent during the dry period of the year, whereas in the rainy season they produce less succulent reproductive structures that die back after blooming. Four species from Peru are presented here, the latter two new to science. 1) Peperomia espinosae is collected for the first time in Peru. The other collection is the type from Ecuador. It has succulent light green tessellate leaves above, burgundy red and hairy beneath. It produces stalks with alternate sessile leaves and simple short panicles of white, club-shaped spadices. 2) Pe. fraseri is a widely distributed Ecuadorian species. Here we outline its distribution in Peru and its southernmost limit in South America. It presents basal rosettes of light green to red puberulous obovate to rotundate leaves, red beneath; central deciduous stems in the rainy season with several whorls of 2–5 narrow ovate acuminate leaves and 1–4 distal conical panicles, consisting of many conferted, very short, very white fragrant spadices. Its reproductive stems die back completely after fruiting and new plants grow from lateral tubers. 3) Pe. renzopalmae is a plant of unknown locality, sold in many markets in northern Peru as a medicinal and magical plant, suspected to come from Huancabamba, Piura. It produces basal subpeltate light green orbicular leaves looking like coins, stems with aerial secondary rosettes of petiolate non-peltate cordate leaves and panicles very different to all other species of this subgenus. 4) Pe. ricardofernandezii — formerly mistaken as Pe. fraseri — shares sometimes its habitat with this species but presents narrower, more succulent and acuminate leaves. A striking difference is the persistence of succulent stems produced at the center of basal rosettes that bear alternate leaves, never whorled as in Pe. fraseri. These stems are perennial and continue branching from sub-terminal buds.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"49 1","pages":"116 - 129"},"PeriodicalIF":1.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80123149","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}

Here, we used nuclear microsatellite and chloroplast markers to examine reticulate evolution involving Haageocereus and Espostoa. Microsatellite data indicate that hybrids between Espostoa and Haageocereus are present and that hybridization has gone beyond the F1 generation, with sampled plants being either F2 or backcrosses, including several individuals that based on morphology were initially identified as Haageocereus. These populations meet the criteria of hybrid swarms. Together, plastid and nuclear markers indicate that Haageocereus, more abundant in the populations, was the pollen donor in all cases examined.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"18 1","pages":"102 - 112"},"PeriodicalIF":1.5,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73413258","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}

A similar hybrid was produced by Charles H. Uhl in the USA, but using Echeveria aff. affinis as one parent. We discuss ×Sedeveria ‘Blue Mist' in the context of Uhl's hybrid that was created for cytogenetics research purposes. ×Sedeveria ‘Blue Mist' is a small, rosulate to short-stemmed plant with visually striking blue-purple leaves and more or less uniformly bright crimson red flowers reminiscent of those of E. affinis, at least colour-wise. With age the flowers fade to whitish, a floral colour associated with S. craigii. Plants very slowly branch from the base, with the branches being leaning to creeping. The boatshaped, tapering, though often nearly cylindrical leaves of this cultivar are borne very densely in apical rosettes. The combination of these characters clearly separates this cultivar from other cultivars of ×Sedeveria E.Walther. The cultivar name ×Pachyveria ‘Blue Mist’ Mottram was previously published for the cultivar.","PeriodicalId":50413,"journal":{"name":"Haseltonia","volume":"12 1","pages":"52 - 57"},"PeriodicalIF":1.5,"publicationDate":"2020-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79189130","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}
