From a socio-cultural point of view, they are elements of the Lisbon history. These botanic garden-museums have the responsibility to keep the heritage from the past and provide a legacy for the future in order to preserve the biodiversity ex situ. The JMAT was created as “Jardim-Colonial” in 1906 and transferred to the present site in 1914. The building of the Temperate and Hot Greenhouses at the northern limit of Cold Greenhouse “Estufa Fria de Lisboa” took place in the sixties. Taxonomic studies were undertaken on specimens by the authors since the seventies. This communication now includes only succulent plants. A brief summary of their historical evolution knowledge, the presentation of some species, their conservation status according to the categories of the Red List of Threatened Plants of IUCN and their uses are presented. The families that include the studied species are: AIZOACEAE, AGAVACEAE, ALOEACEAE, ASCLEPIADACEAE, BROMELIACEAE, CACTACEAE, COMMELINACEAE, CRASSULACEAE, EUPHORBIACEAE, and PORTULACACEAE. Other families that include too non-succulent xerophytes spiny shrubs are presented, such as: CYCADACEAE, RHAMNACEAE and ZAMIACEAE. The green spaces studied are important as a vegetal patrimony for research, didactic, educational, artistic and leisure purposes. Keywords: botanic gardens; Lisbon; succulents; conservation, cacti. INTRODUCTION The botanic gardens have a responsibility to safeguard their heritage and provide and pass on a legacy for future generations as well as helping to ensure the maintenance of plant diversity and to preserve the biodiversity ex situ. The “Jardim-Museu Agrícola Tropical”(JMAT), the Cold (CG), Temperate (TG) and the Hot (HG) Greenhouses in Lisbon are valuable treasures and they are a rich heritage having a strong relationship with the society, such as a source to the environmental education. Nowadays the mentioned green spaces have important plant collections of the Lisbon vegetal patrimony, being considered garden-museums. Taxonomic studies have been undertaken on those mentioned sites by the authors since seventies (Liberato,1994, 2001; Caixinhas,1994, 2002). The named “Jardim-Museu Agrícola Tropical” was created in 1906 as “Jardim Colonial” in order to support the Agronomic Colonial Teaching. This garden was transferred to the present site in 1914. Different Kings used this site since first middle of 18th century for their leisure. One of the purposes of “Jardim Colonial” was the promotion and the introduction of the economic tropical and subtropical plants. These objectives are still being accomplished nowadays. The Lisbon Cold Greenhouse was building in twenties. At its northern limit was building another greenhouses called Temperate and Hot Greenhouses in the sixties. The aim of this communication concerns a brief summary of historical evolution knowledge of the Cacti and Succulent, the presentation of some species, their conservation status according to the categories of the Red List of Threatened Plants of IUCN and their uses. MATERIAL AND METHODS The taxonomic study of cacti and others succulent plants conserved in JMAT, LG, TG and HG, their wild origin and uses, where done using Walters et al. (1984), Huxley et al. (1982), Cullen et al. (1995, 2000), Mabberley (1997) and Erhard et al. (2000). When necessary, the exemplars were compared with verified herbarium specimens. The names authors follow Brummitt & Powell (1992). The conservation status is according to IUCN threat categories (Walter & Gillet, 1998). The families that include the studied species are: Aizoaceae, Asclepiadaceae, Cactaceae, Crassulaceae, Euphorbiaceae, Portulacaceae, Agavaceae, Aloeaceae, Bromeliaceae and Commelinaceae. Our work includes too non-succulent xerophytic spiny shrubs, such as: Cycadaceae, Zamiaceae, some Euphorbiaceae and Rhamnaceae. The historical evolution of the succulent plants knowledge follows Caixinhas 2002). RESULTS The taxa, the IUCN categories, the wild origin of species, their uses and distribution by the Lisbon Garden-Museums studied are presented on Table 1. The taxa above the rank of family and the names of these follow Cronquist (1981, 1988). The families and species are listed in alphabetic order. The succulent plants’ geological history is scattered because few fossils have been found. This explains the reputation of these plants regarding mysteries and contradictions. The Cactaceae family has a remote origin, several species of Opuntia belong to the Eocenic period in the state of Utah (USA). The most ancient illustration of a succulent plant can be clearly recognized as the inflorescence of Kalanchoe sp. patent on the bas-relief of the Great Temple of Thutmose III, at Karnak, Egypt. The discovery of the American continent allowed the Cactaceae to reach Europe. According to several authors, the first cactus to enter in England was, apparently, a Melocactus, in 1581, a particularly miserable choice at the time, because the climate conditions were no ideal for the plant’s needs. Like the cacti, the other succulent plants were also known in the Europe of the Renaissance. At the time of the discovery of the maritime way to India, the Portuguese sailors, certainly, spread the knowledge about succulent plants with origin in South Africa. During the 16th century, the foundation of Botanic Gardens benefited the culture of medicinal plants, many of them succulents, so we can still find a magnificent collection of these plants in the Botanic Garden of Padova. 2 The families Agavaceae, Aloeaceae, Bromeliaceae, Cactaceae and namely Crassulaceae have a marked diurnal variation in acidity, mostly due to malic acid, which was named Crassulacean acid metabolism (CAM). These plants have the stomata open during the night and fix CO2 to produce malic acid which is stored in the cell vacuole. Cereus spp. are used as protective shields against electromagnetic radiations from computers. In Linnaeus’ Philosophia Botanica (1751) includes in group 46, Succulentae. Many botanists study too cacti uses and other succulent plants, such as: De Candolle author of Plantarum Historia Succulentarum, Joseph de Salm-Reifferscheidt-Dyck (1834), Georg Engleman (1856), Lord Britton and Nelson Rose (1903), Hermann Jacobsen in 1954, published an important monography. In the past century in the American continent there are several works, namely the work by the Mexican cactalogist Helia Bravo. CONCLUSIONS We can reach the following conclusions: The overall number of taxa growing in the garden-museums studied includes 122 species, of which 10 are Pinophyta, 68 Magnoliopsida and 44 Liliopsida. Among the studied taxa, according to the IUCN Red List Categories, Encephalartos ferox, E. lebomboensis, E. lehmannii, Dioon edule and Schlumbergera truncata have the status of Rare; Echinocactus grusonii has the status of Endangered; Encephalartos altensteinii, E. horridus, E. paucidentatus, Schlumbergera truncata and Selenicereus anthonyanus have the status of Vulnerable; Ceratozamia mexicana, Opuntia littoralis and Rhipsalidopsis gaertneri have the status of Indeterminate. Within the garden-museums studied, taxa of cacti and succulent plants were found from all hot sites of world. The studied taxa provide a wide range of uses, such as, food, edible fruits, vegetables, forage, medicinals, electromagnetic radiations protection, fibbers, living fences and very much as ornamentals. The presented Lisbon garden-museums are privileged spaces for the preservation of biodiversity ex situ. They are very important for research, as well as for didactic, educational programmes, artistic and leisure purposes. We have the responsibility to preserve this heritage from the past and provide a legacy for the future. 3 REFERENCES Bravo, H. (1937) – Las Cactaceas de Mexico.
