Perichaetial leaves 2 x 0.8 mm long, ovate-acuminate, ecostate.

The plants are generally unbranched and have broad, squarrose leaves. The costa may be single, double, or lacking even on the same stems, and the basal and alar cells also vary on the same plants in wall thickness, pitting, and color. T he characteristic pitting ofthe upper cells is not pronounced in Mexican plants available for study.
JaegerinaguatemalensisBartr. has ovate, long-acuminate leaves costate to the apex and serrulate throughout.
