    Chamaecrista inaguensis sensu Britton & Rose, 1930, p. 282.

    Minutely strigulose; major lvs up to 3-7(-7.5) cm, the lfts 2-4(-5) pairs, varying from elliptic subacute or lance- or oblance-elliptic to obovate and obtuse to emarginate; petiolar gland tack- or trumpet-shaped, (0.4-)0.6-1.5 x (0.4-)0.45-0.8(-0.9) mm, as long as to 0.9 mm longer than diam of head; pod of var. lucayana.— Collections: 15.

    Coppice, in either sandy or rocky soils, sometimes on exposed rock, maritime or submaritime, extreme s. Bahamas (Inagua I.); Turk and Caicos Is. (Grand Turk, N., Middle and S. Caicos, Ambergris and Pine cays); and n.-w. Hispaniola (Ile de la Tortue).—Fl. X-III, VI, perhaps irregularly through the year.

    Variable in width and outline of the leaflets, but almost constantly distinguished from var. lucayana by leaflet number, these two to four pairs in all but one specimen (Proctor & Gillis 34033, NY) from North Caicos, of which one branchlet has five pairs. Plants from South Caicos (Millspaugh 9303, GH, NY) and Ambergris Cay (P. Wilson 7687, GH, NY) with only two pairs of broadly obovate leaflets are essentially identical to the type-series of Cassia tortuensis from northwest tip of Haiti.
