Rico; St. Bart’s; Bonaire; hillsides, Curacao; Guiana. 
4. CLEOME PROCUMBENS Jacq. Stirp. Am. 189. pl. 120. 1763

ently also erroneously referred to Jamaica, as Jacquin’s figure of 
the type would seem to represent a well-marked species, not 
collected since its original discovery.

Sandy soil, Pinar del Rio and Isle of Pines, Cuba.

ovate or elliptic, 4-6 mm. long, rounded or obtuse at the apex, 
rounded at the base, the midvein prominent, the lateral venation 
obscure, the petioles 1-2 mm. long; peduncles slender or filiform, 
4-8 mm. long; sepals obtuse, 2-2.5 mm. long; petals yellow, 
oblong or oblong-obovate, obtuse or acutish, 3-4 mm. long; 
stamens about two-thirds as long as the petals; filaments filiform;
