Both authors however included a number of specimens having axillary flowers with corolla tube ca. 3 mm long, representing the southern half of the species’ distribution. Further analysis (see under <i>A. urceolata</i> <i>sp. nov</i>. section) confirmed that specimens included in <i>Alyxia caletioides</i> by both authors actually represent two distinct species. <i>Alyxia caletioides</i> is here confirmed as a species following Boiteau’s (1981) and Middleton’s (2002) opinions, but with a narrower distribution and a more stable morphology.</p><p><b>Distribution and habitat:</b> — <i>Alyxia caletioides</i> occurs only in the northwestern part of Grande Terre, on ultramafic substrates.
