Resumen:
Pollen morphology of 16
species of the genera Corchorus, Heliocarpus, Luehea, Mollia and Triumfetta (Malvaceae, Grewioideae)
distributed in southern South America were studied by light and scanning
electron microscopy. Pollen grains are 3-zonocolporate, isopolar, radially symmetrical,
subspheroidal to prolate and medium to large in size. Exine sculpture varies
from bireticulate reticulum with perforated lumina to densely tectate-rugulate
or tectate-microreticulate. Pollen morphological characteristics from light
microscopy were used in a multivariate analysis to assess variation within and
among the genera. Principal components analyses (PCA) clearly separate five
groups based on pollen shape and size, colpus length, endoaperture height and
width, and exine thickness.
