Description

  • Stems 101 m tall.
    Leaves simple or pinnate; blade cuneate in simple leaves, 72-86 cm long, 25-26 cm wide, with 16-17 primary veins per side; apical pinna 35- 36 x 7-8 cm, wider than the other pinnae.
    Inflorescences arching; peduncle 65-72 cm long, 3-4 mm diam., ± terete sparsely covered with reddish brown peltate-lacerate scales; rachis 4-6 cm long, with similar scales to those of peduncle; rachillae 4-8, 14-18 cm long, 1-2 mm diam. at anthesis, the proximal ones not swollen basally and with a sterile part <1 cm long, usually ascending, subtended by bracteoles to 6 cm long proximally. glabrous; endosperm homogeneous.

Materials Examined

  • VENEZUELA. TACHIRA: La Buenana. 6-12 km W of Quebrada Colorado. ca. 3S km SSE of San Cristóbal. 07'28'N. 72'09'W, 600-1000 m. 19 Mar 1981 . Liesner & Gonzalez 10795 (MO. NY). This is an imperfectly known taxon. It seems to be clearly separated geographically and ecologically from the other two varieties here recognized. Whereas var. longepetiolata and var. roseospadix are sympatric in part of their ranges in Central America. var. Cualrecasasii occurs almost 1000 km to the east. This gap is found in other species of Prestoea, and coincides with lower elevations in eastern Panama. The occurrence of simple leaves and homogeneous endosperm are diagnostic for this variety and have not been found in the other two varieties. (Gloria Galeano & A.
