Discusión taxonómica

Ghiesbreght 366 (BM, K) is possibly this species, but the specimens are too incomplete to be certain. These specimens completely lack flexuous, catenate hairs on the axes below, but otherwise agree with H. pulcherrima in the nearly naked sori and dark axes (though castaneous rather than atropurpureous). Chiapas material lacks acicular hairs and is generally less hairy than specimens from Jamaica. Antillean material has atropurpureous axes, is densely pubescent with catenate hairs and a few acicular hairs intermixed, and the indusia are poorly differentiated and ciliate with catenate, glandular hairs. Specimens from Costa Rica and Panama are similar to Antillean material.A
