FIASCHI, Pedro; CRUZ-BARROS, Maria Amelia Vitorino da  and  CORREA, Angela Maria da Silva. Palynotaxonomic study of southeastern Brazilian species of Schefflera (Araliaceae). Rodriguésia [online]. 2008, vol.59, n.4, pp.873-886. ISSN 2175-7860.

Morphological studies of the pollen grains of 18 species of Schefflera from Southeastern Brazil were carried out: S. angustissima, S. calva, S. capixaba, S. cordata, S. fruticosa, S. gardneri, S. glaziovii, S. longipetiolata, S. lucumoides, S. macrocarpa, S. malmei, S. morototoni, S. selloi, S. spruceana, S. succinea, S. villosissima, S. vinosa e Schefflera aff. varisiana. The pollen grains analysed are medium, rarely small, with triangular to subtriangular amb, anguloaperturate, oblate spheroidal to prolate spheroidal, 3-colporate, and reticulate heterobrochate or rugulate-reticulate ornamentation. Phylogenetic relationships among some of the studied species are discussed based on the obtained results.

Keywords : Araliaceae; Didymopanax; pollen grains; Schefflera.
