Puya vestita is a plant type from the family of bromeliads (Bromeliaceae).
The main area of distribution is from the Cotopaxi volcano in Ecuador to the Colombian department of Nariño on stony slopes at an altitude of 2280 to 3250 meters. It was first described in 1888 by Édouard-François André .
description
Puya vestita grows up to two meters in size, with the leaves up to 30 centimeters long and 2.4 centimeters wide. While the top of the leaf is bare, light brown scales cover the underside. The edges are lightly sawn and have weakly developed six millimeter teeth.
The cone-shaped compound inflorescence is covered in reddish wool. Three to four sessile flowers sit on one of the branches that have receded into leaf cushions . The triangular primary bracts are so large that they almost hide the flower. Their edges are roughly serrated and taper to a long, linear leaf shape at the tip . The three centimeter long bracts of the flower are boat- shaped to egg-shaped and taper to a very point. With a length of 1.8 to 3.0 centimeters, the egg-shaped sepals are only about half as long as the 6 centimeters, light green and blunt petals . They resemble the stamens .
The seeds of the species are very similar to those of Puya hamata . They have circumferential wings clearly separated by a line and are spherical to polygonal. They are also comparatively thick.
