It has been reported from Dominica, Dominican Republic, Puerto Rico, Virgin Islands, and Lesser Antilles. <i>Phenology</i>. April to June. <i>Parasenegalia muricata</i> flowers from <i>Local names and uses</i>. Local names include spineless acacia, amarat, tamarindo cimarrón, tantacayo, and tender a caillou (Rico Arce, 2007). Wood has sometimes been used for construction. <i>IUCN Red List category</i>. <i>Parasenegalia muricata</i> is Data Deficient (DD) at this time (IUCN, 2001). The species is relatively common in Puerto Rico, the Virgin Islands, and several of the other Lesser Antilles. The limited habitat suggests that the species should be evaluated. <i>Discussion</i>. <i>Parasenegalia muricata</i> is a common species of dry, wooded hillside and cactus scrub forest throughout much of the Caribbean. This taxon has the largest leaflets of the species in the genus <i>Parasenegalia</i>, being 8–20 mm long and 4–11.3 mm wide, and with slightly revolute margins. Though <i>P. lundellii</i> sometimes has leaflets exceeding a length of 10 mm, the leaflets are narrower (never exceeding 4 mm), and the leaflet margins are not slightly revolute. <i>Specimens examined</i>.
