“…During the 19th century, few naturalists were focussed on investigating the flora of the Cabo Verde Islands. Two of those, namely Feijó at the end of the 18th century (Gardère et al, 2019) and Schmidt at the end of the 19th century (Exell et al, 1952) were, between them, responsible for the first records of more than 60% of the endemic flora (Figure 1A).…”

“…The first thorough botanical survey of the Cabo Verde archipelago was performed by the Portuguese naturalist João Silva Feijó who stayed in the islands from 1783 to 1797, and collected the earliest herbarium for this archipelago (Gardère et al, 2019). In the 19th century the islands began to attract more interest, and field expeditions were made by naturalists, including Chrétien Smith in 1816 (Tuckey, 1818); John Forbes in 1822 (Chevalier, 1935); Charles Darwin in 1832 (Fitzroy, 1839); Samuel Brunner in 1838 (Barbosa, 1961); Joseph Dalton Hooker in 1839 (Rico et al, 2017); and Theodor Vogel in 1841 (Webb, 1849).…”

Bayesian Methods to Analyze Historical Collections in Time and Space: A Case Study Using Cabo Verde Endemic Flora

Biological collections, including herbarium specimens, are unique sources of biodiversity data presenting a window on the history of the development and accumulation of knowledge of a specific geographical region. Understanding how the process of discovery impacts that knowledge is particularly important for oceanic islands which are often characterized by both high levels of endemic diversity and high proportions of threatened taxa. The archipelagos of the Macaronesian region (i.e. Azores, Canaries, Savages, Madeira, and Cabo Verde) have been the focus of attention for scientific expeditions since the end of the 17th century. However, there is no integrated study describing the historical process of collecting, discovery and description of its flora. Using as a case study the Cabo Verde endemic angiosperm flora, we review the history of collecting in the flora and apply a Bayesian approach to assess the accumulation of species discovery, through time and space across the nine islands of the archipelago. Our results highlight the central role not only of natural characteristics (e.g. area, age, maximum altitude and average value of the terrain ruggedness index) but also historical factors (i.e. the location of major harbors) for the development of knowledge of the flora. The main factors that have determined the process of species description in the archipelago and how this impact our understanding of diversity patterns across archipelagos are discussed.

“…The historic framework of the three botanical gardens was retrieved from several types of documents, such as the descriptions of the scientific expeditions performed in the late 18th century in the Portuguese territories overseas, the so-called “ Philosophical Journeys ” [ 22 , 49 ], and other historical documents with descriptions and information referring to their history, e.g., [ 18 , 23 , 24 , 45 , 47 , 48 , 49 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 ].…”

Botanical gardens have long contributed to plant science and have played a leading role in ex situ conservation, namely of threatened tree species. Focusing on the three botanical gardens of Lisbon (i.e., Botanical Garden of Ajuda—JBA, Lisbon Botanical Garden—JBL, and Tropical Botanical Garden—JBT), this study aims to reveal their natural heritage and to understand the historical motivations for their creation. Our results showed that these gardens contain a total of 2551 tree specimens, corresponding to 462 taxa, within 80 plant families. Of these, 85 taxa are found in the three gardens, and more than half of the taxa are hosted in JBL (334 taxa), whereas 230 and 201 taxa were recorded in JBT and JBA, respectively. The motivations for the creation of each garden are reflected in the different geographic origins of the trees they host in their living collections. The Palearctic species are dominant in JBA and JBL, and Tropical trees prevail in JBT. With more than 250 years of history, these gardens hold an invaluable natural and historical heritage, with their living collections providing valuable sources of information for the conservation of threatened plant species, at local and global scales.

The previous taxonomic study of Cabo Verdean bellflowers (Campanula L., Campanulaceae) recognized four endemic species. In light of a recently published geometric morphometric study, the reassessment of the Campanula jacobaea complex allows to restrict Campanula jacobaea C. Sm. ex Webb to the island of Santiago. A new lectotype is proposed for this name that conforms to the protologue. Three further new species are described: Campanula monteverdensis Gardère from São Vicente, Campanula fransinea Gardère and Campanula cochleromena from São Nicolau, and Campanula vicinituba Gardère from Santo Antão. Campanula hortelensis Gardère, also from Santo Antão is placed in synonym of Campanula feijoana Gardère. Seven species are recognized in the Cabo Verde archipelago including Campanula bravensis (Bolle) A. Chev., the most widespread bellflower occurring in all southern mountainous islands. A determination key, descriptions, photographs and a distribution map are provided. Resumo
