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... -

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... -
