Dicotyledones in some green areas in Lisbon. The achlamydeous and the haplochlamydeous.

There are several remarkable green areas in Lisbon, namely “Jardim-Museu Agricola Tropical”, “Tapada da Ajuda” and “Estufa Fria de Lisboa”. Plant collections from different floristic regions of the world are conserved in these areas. Several species of achlamydeous and haplochlamydeous dicotyledones included in these collections can be found. The identification of the species was made through morphological external characters of specimens cultivated in those areas. The taxa, their wild origin, some of their uses by man and their presence in the respective green area are pointed out. For the threatened species, the conservation status according to IUCN categories is mentioned. The areas studied are privileged as they are responsible for the ex situ biodiversity conservation. Presently these areas are also very important for research, as well as for didactic and educational programmes.
