EREMOLAENA Baill.

Bull. Mens. Soc. Linn. Paris 1: 413 (1884).

TYPE. — Eremolaena humblotiana Baill.

The genus Eremolaena comprises two species, both of which have been recognized for many decades. Vegetatively they closely resemble several species in the two putatively related genera, including Pentachlaena orientalis , Perrierodendron capuronii , and P. occidentalis , and can sometimes be difficult to recognize without flowers and/or fruits. Distinctive features of the genus include strongly unequal sepals (the outer two being much smaller), an ovary with 3 carpels (vs. 2 in Perrierodendron and 5 in Pentachlaena ), and a dehiscent fruit (also present in Pentachlaena ) containing only 2 seeds in each locule.
