Astrocaryum mexicanum [22] or even in other palm species, such as in Geonoma schottiana [23], Phoenix dactylifera [24], and Oenocarpus bataua [25], showed similar reproductive strategies (1) The demography of the palm Astrocaryum mexicanum is described from a study of six permanent plots in a tropical rain forest in Veracruz, Mexico, during 7 years. (2) There are differences between the plots in transition probabilities, survival and fecundity estimates for some age classes. (3) Yearly estimates of transition probabilities from one stage to the next are about 0 10 individual The Astrocaryum mexicanum Liebm. ex Mart. (1853) is a species with solitary stem, cylindrical, 1,5-6,5 m tall and of 4-7 cm of diameter thickly covered in correspondence to the scars of the foliar bases of rings of flat spines, black, 3-6 cm long, facing various directions. Apparently simple leaves, or irregularly divided in the young plants The genus Astrocaryum (Arecaceae) The palm genus Astrocaryum with 40 species is common in tropical South America extending northwards reaching Central America and Trinidad. Twenty-six species grow to male- and female-phase inflorescences of the understorey dominant palm Astrocaryum mexicanum at the Los Tuxtlas tropical rain forest. In six forest fragments ranging from 2 to 700 ha, we collected all floral visitors, pollinators and non-pollinators, to male- and female-phase inflorescences at the time of their greatest activity. plots was 365 m (Table 1). Data on the number of. infructescences produced from 1975 to 1986, and on. the increase in height from 1975 to 1982 (M. MartInez-.
