AN ACCOUNT OF MORPHOLOGICAL AND STRUCTURAL CHARACTERIZATION OF AMERICAN MIMOSOIDEAE POLLEN. PART I: TRIBE ACACIEAE

Museo Argentino de Ciencias Naturales "B. Rivadavia", CONICET, Av. Angel Gallardo 470, C. C. 220, C. P., 1405 Buenos Aires, Argentina, e-mail:cidcaccavari{at}infoshopdte.com.ar edome{at}muanbe.gov.ar

The results of a pollen study of 77 American species of Acacia (tribe Acaciae) characterizes pollen among the different New World taxa of the compound-pollen Mimosoideae on the basis of the most relevant morphologic and structural features.

Two pollen types and five subtypes are recognized and summarized in the diagnostic key presented herein. As a result of the species studied, some newly observed structural features are now utilized; these features modify the previous characterization of the pollen of Acacia, and include frequent ornamentation of the suprasubreticulate or supramicrorugulate exine, presence of subpseudocolpi in some species, and presence of a bistratified granular infractectal layer in the subgenus Aculeiferum but not in the section Filicinae.
