This article investigates the factors influencing the frequency of flower colour polymorphism in the Cuban cactus Leptocereus scopulophilus, where four flower morphs have been reported. We determined whether the colour of the tepals is a discrete variable and estimated morphs frequency in the population. To explain the frequencies of the flower morphs, we compared their dimensions. We also contrasted pollination success and flower florivory of the most frequent morphs. Leptocereus scopulophilus presents discrete values of tepal colour for all the morphs, including the albino morph reported in this study for the very first time. The light salmon morph is the most frequent in the population. This could be explained by the higher number of ovules and fruits it produces. Pollination in the species is confirmed to be exclusively nocturnal, and florivory is similar for the magenta and light salmon morphs.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45164010","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 new garden, the Royal Botanic Institute of Glasgow replaced it in 1818 at Sandyford in the city. Thomas Hopkirk’s collection formed the basis of the garden. When a larger garden was needed, the Glasgow Botanic Garden was set up in its present location in 1840. William Jackson Hooker made a significant contribution to the development of the garden in the first half of the nineteenth century. As editor of Curtis’s Botanical Magazine for thirty-six years and Director of Kew Gardens, he was a major figure in the field of botanical science. This article details the history of the gardens with particular reference to Hooker. It also reflects on the cacti and other succulents in the early gardens and details lists produced between 1813 and 1825.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45442042","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}

Nonnative species make up nearly ninety percent of the country's flora. Succulents, numbering over a hundred, constitute a relatively small proportion of the total. Most, if not all, of the country's non-native succulents are a consequence of introduction, escape from cultivation or careless disposal. Carpobrotus edulis and its hybrids pose a threat to native flora. The poisonous Cotyledon orbiculata poses a threat to livestock. These two species are controlled, to some extent, by restrictions on sale and distribution. Conservation measures, other than those applied to these species, are limited. The conservation authorities in New Zealand should be alert of the potential threats from some other succulent plants, especially at local level.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47764931","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}

While Mammillaria heyderi subsp. gaumeri is a relatively common cactus inhabiting various types of biotopes (from stabilised coastal sand dunes to dry tropical deciduous forests), Mammillaria columbiana subsp. yucatanensis has been re-discovered in its habitat near Progreso (type locality) only very recently and only a few specimens have been so far reported. Thus, although recorded from other parts of Mesoamerica, M. columbiana subsp. yucatanensis should be considered as a very endangered plant in Yucatán Peninsula, deserving the special protection status. The biggest threat to both cacti is the destruction of their habitats due to the urbanisation of the coastal areas.","PeriodicalId":50726,"journal":{"name":"Bradleya","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2022-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49641267","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}
