LEYTHON, Sirli  e  JAUREGUI, Damelis. Morfología de la semilla y anatomía de la cubierta seminal de cinco especies de Calliandra (Leguminosae-Mimosoideae) de Venezuela. Rev. biol. trop [online]. 2008, vol.56, n.3, pp.1075-1086. ISSN 0034-7744.

Seed morphology and anatomy of the seed coat in five species of Calliandra (Leguminosae-Mimosoideae) from Venezuela. Calliandra is an exclusively Neotropoical genus with 135 described species. There are 30 species in Venezuela. We studied seed morphology and the seed coat anatomy of five species: Calliandra riparia Pittier, Calliandra glomerulata Karsten var. glomerulata, Calliandra magdalenae (DC.) Benth. var. magdalenae, Calliandra surinamensis Benth. and Calliandra falcata Benth., to establish simililarities and differences amongst taxa for taxonomic characterization. Of the evaluated characters, 10 quantitative characters and 3 qualitative characters were selected as the most informative for the separation of species. Seed morphological characters of taxonomic value are form and size. Thickness of the light line, number of layers and space between the osteosclereids constitute distinctive characters. Rev. Biol. Trop. 56 (3): 1075-1086. Epub 2008 September 30.
