The flowers are 6.81 to 11.44 mm in length and 2.41 to 5.24 mm in width, and are located in the apical rachillae of significantly shorter length (Table 2).
inajai, inflorescencis with up to 35 rachillae. In the present work, the number of rachillae varies from 18 to 36.
(2006) observed only staminate flowers in the apical rachillae of four of the seven inflorescences of Astrocaryum aculeatum studied, which is a new finding for this species.
Epicarp covered in indument, setose or spiny; pistillate flower usually one per rachilla (some rachillae, usually those located at the base of the rachis, are sometimes found with 2-3 flowers in the most vigorous plants)--21
Acaulescent or subacaulescent (to short-stemmed) palms; petiole rusty-red tomentose; rachis up to 30 cm long, bearing up to 70 rachillae up to 20 cm long--14
Palms with large stems; petiole not rusty-red tomentose; rachis usually longer than 40 cm, bearing more than 90 rachillae usually longer than 25 cm--15
This group is defined by the unilateral staminate flowers on staminate rachillae and conspicuous fiber clusters organized in one circle in the thick endocarp (Fig.
4), peduncular bract thin, staminate flowers spirally arranged on staminate rachillae and dispersed fibers within a thin endocarp (Fig.
phalerata complex but have spirally arranged staminate flowers on staminate rachillae similar to those of the A.
