Larva and pupa of Loncophorus pustulatus (Champion, 1903) (Curculionidae: Curculioninae: Anthonomini) are described, illustrated and compared with descriptions of immatures of two other species of Loncophorus. Weevil larvae were found inside aborted flowers on the ground under Ceiba speciosa (A. St.-Hil.) Ravenna (Malvaceae), in the city of Sgo Paulo, State of S5o Paulo, and reared to adults in...
The Neotropics is the most species-rich area in world, and mechanisms that generated maintain its biodiversity are still debated. This paper contributes to debate by investigating evolutionary biogeographic history of genus Ceiba Mill. (Malvaceae, Bombacoideae). comprises 18 mostly Neotropical species, largely endemic two major biomes, seasonally dry tropical forests (SDTFs) rain forests. Its s...
Wissadula periplocifolia (L.) C. Presl (Malvaceae) is commonly used in Brazil to treat bee stings and as an antiseptic. The antioxidant properties of its extracts have been previously demonstrated, thus justifying a phytochemical investigation for its bioactive phenolic constituents. This has yielded five new sulphated flavonoids: 8-O-sulphate isoscutellarein (yannin) (1a); 4'-O-methyl-7-O-sulp...
The fossil record evidences an old origin and diversification of Malvaceae in the Northern Hemisphere. central Tibetan Plateau was at a low elevation with monsoon influence during Eocene, allowing development subtropical flora containing Malvaceae. taxonomic study fossils from Eocene what is now still ongoing. Jianglang flora, are attributed to sub-families Tilioideae Sterculioideae, compared m...
