Remarks

This is another rare species of Tanystylum collected for the first time in Martinique, though the most abundantly sampled here in this genus. Most specimens were collected on the Atlantic coast of Martinique, except MNHN-IU-2016-1309, which was sampled near the southern cape of the Island. This is the first record of the species out of the Caribbean Sea stricto sensu.

Distribution

Caribbean ( Venezuela, Colombia, Martinique).
