A plant, or rather portion of a plant, of Uncinia brevicaulis, var. robustior, natural size. 



Figure 1. — Glume and stamens from which the anthers have fallen.

The drawing represents a specimen collected by De ITsle in Amsterdam Island. The 

 tip of the spike is male only, and the whole plant is more robust, otherwise it differs very 

 little from the form which we call gracilior.
