A new species of Magnolia is described for the flora of Brazil, based on material from Bahia and Minas Gerais states. This species represents the first record of Magnoliaceae in the Northeastern region of Brazil. Magnolia brasiliensis differs from all other Brazilian species of Magnolia by having adaxially glossy leaves and differs from M. ovata by having a lower number of stamens and carpels. Despite its large extent of occurrence, the conservation status attributed to the new species is Endangered, mainly based on the low number of mature individuals in each subpopulation (< 50) and an area of occupancy of less than 16 km2.  相似文献

Two endangered new species of Marsdenia R. Br. (Asclepiadoideae, Apocynaceae) from the semi-arid region of Brazil are described and illustrated: M. breviramosa (south-western Bahia) and M. nana (northern Minas Gerais). They are shrubs closely related to M. zehntneri and, like that species, are also associated with calcareous outcrops. The former can be recognised by linear leaves arranged in small, compact shoots and the latter is a subshrub less than 50 cm high whose flowers are unique because of the adaxially villous corolla and long-rostrate gynostegium.  相似文献

Two new species of Microlicia from campos rupestres of Minas Gerais are described, illustrated and compared with their relatives. Microlicia crassa sp. nov. is similar to M. formosa, and M. maculata sp. nov. is similar to M. isophylla and M. tetrasticha. The trichomes covering both surfaces of the leaves of the two new species and their relative, M. isophylla may be characterized as sessile glands under a stereomicroscope, but anatomical studies revealed the presence of a short stalk. Microlicia crassa and M. maculata are assessed as “Endangered”, according to the IUCN categories and criteria.  相似文献
