El Catálogo de las Plantas de Cuba compila los taxones (especies y subespecies) de licófitos, helechos, gimnospermas y angiospermas presentes en Cuba, ordenados en inventarios por familias y territorios. De cada taxón reconocido como miembro de la flora de Cuba se indica su nombre aceptado como correcto (así como la sinonimia relevante y los falsos...

The taxonomic status of Pinguicula lithophytica had been challenged both in publications and in discussions. It was proposed that P. lithophytica is conspecific with Pinguicula jaraguana. Both taxa represent Cuban endemics but they are from widely separate locations. Comparison with P. jaraguana was not considered by Panfet Valdés and Temple as the...

We present here pollen morphology of 12 native taxa of Lentibulariaceae from Western Cuba with the aim of surveying pollen traits useful for species identification. Pollen grains were studied using light microscopy and scanning electron microscopy to search for new characteristics to contribute to the taxonomy of Lentibulariaceae from western Cuba...

Several names of the genus Pinguicula have been found to need typification or corrections to previous typifications. Analyses of original material and literature related to each name have led to the designation of 17 lectotypes, five neotypes and one epitype. Also five previously cited ‘holotypes’ were corrected to lectotypes. Notes discussing the...

Pinguicula L. ser. Albidae Casper compreende três espécies endêmicas de Cuba com padrões de distribuição restrita associados a habitats específicos. Numerosas transformações naturais e antrópicas nesta área têm influenciado o isolamento das populações o que pode levar à diferenciação genética intraespecífica como consequência da interrupção do flux...

The carnivorous plant Pinguicula filifolia occurs in western Cuba and shows a restricted distribution due to habitat specificity associated with poor wet soils. Its populations are distributed mainly in south Pinar del Río (Cuba) and in Isla de la Juventud. Plants from one isolated location in NW Pinar del Río shows morphological differences with r...

Background: Phenotypic variations have been observed in populations of west Cuban Pinguicula species. Such populations occur in patches under different ecological conditions associated with specialised habitats and separated by geographical and ecological barriers, which can lead to morphological differentiation. Aims: To analyse morphological dive...

Pinguicula filifolia C. Wright ex Griseb. is a carnivorous plant endemic in western Cuba. New features on the generation time habit and leaf morphology of this species are described and illustrated emphasizing its heteromorphic habit, based on studying living plants in nature and vouchers. A comparison of morphological characters of leaves among P....

The aim of this work was to compare the antioxidant activity of the peel and pulp extracts of Garcinia tinctoria (yellow mangosteen) fruits. Total phenolic content (TPC) assay showed that the peels contained higher phenolic content than the pulps. Ferric reducing antioxidant power (FRAP) test indicated that the peel extract of G. tinctoria fruits s...

This paper describes and illustrates a new species of Pinguicula L. from the central region of Cuba: Pinguicula lithophytica C. Panfet-Valdés & P. Temple. The new species is included in the section Agnata, subgenus Isoloba, with morphological relationship to Pinguicula jackii Barnhart. This is only the second species of Pinguicula to have been foun...

The internal transcribed spacer (ITS) region of 18S-26S nuclear ribosomal DNA (nrDNA) in seven species and one variety of Pinguicula (Lentibulariaceae) in Cuba has been sequenced. Although the eight taxa have been taxonomically divided into two subgenera such as Isoloba and Pinguicula with the other species grown in the other regions, and further t...

At present, plants are the main source of obtention of most of the drugs that may be useful for treating cancer. A mixture of polysaccharides was extracted from the leaves of Argemone mexicana L. plant, also known as Cardo Santo, collected in the flowering period. The method of incorporation of tritiated Thymidine was used to determine the effect o...

Three new species are described and illustrated: Ardisia manitzii from the Isla de la Juventud (western Cuba), related with Ardisia mogotensis (another western Cuban endemic), Myrsine pipolyi f...

A species new to science, belonging to Wallenia subg. Homowallenia, has been discovered in the Sierra Maestra, Granma Province, in E Cuba. It is described and illustrated as W. maestrensis, then compared with its closest relative, W. bumelioides, known from several Cuban provinces and also illustrated.
