A preliminary study of genetic diversity in populations of Montrichardia Crueg. (Araceae) estimated with molecular markers.
The two species of (Araceae) are perennial herbs of great ecological, economic, and ethnobotanical importance that form populations by clonal growth and sexual reproduction. Here, genetic diversity was studied within a drainage system distant from Amazonia. Five populations were sampled from the Rio Parnaíba Delta (northeast Brazil) and two outside... -

Diversity of Bignoniaceae in coastal Piauí, Northeast Brazil.
Abstract The present study is a taxonomic treatment of Bignoniaceae from the four municipalities of the coastal region of Piauí state (Cajueiro da Praia, Ilha Grande, Luís Correia, Parnaíba) in Northeast Brazil, based on morphological study of newly collected and existing herbarium material. The study recorded 26 species in 12... -

Measuring relative flower size in Anthurium (Araceae) as a continuous quantitative character.
Relative flower size (RFS) was studied quantitatively in natural populations of Anthurium erskinei (one population) and A. talmonii (two populations) to investigate its potential as a taxonomic descriptor. RFS is defined as the ratio of spadix diameter and transverse floral width in the same region of the spadix. Variation was...
