Randomized trial describes pollen grains of restricted subfamilies in Bromeliaceae, indicating key morphological features.

The aim is to describe the pollen grains of Bromeliaceae subfamilies with restricted geographic distribution.
Acetolysis and scanning electron microscopy were utilized for pollen analysis.
Pollen grains were examined for size, shape, amb, sulcus type, aperture margin, and ornamentation.
Pollen grains were monads, heteropolar, and bilaterally symmetric with distinct variations.
Pollen grains of Puyoideae were large, while others were medium-sized, except for Brocchinia reducta with small grains.
Ornamentation was predominantly reticulate, with some species showing perforate ornamentation.

Almeida et al. (2026) studied this question.
