Hypericum hypericoides subsp. prostratum (Nomenclature)
Plant prostrate, with stems numerous, radiating and branching, forming mats. Leaves narrowly oblong to oblong-spathulate, 3-8(-10) x 1-2.5 mm. Inflorescence-branching pseudo-dichotomous.
Open Pinus forest, grassland and open slopes; (1600-)! 800-2900
Dominican Republic (La Vega, Santiago, San Juan, Peravia).
Subsp. prostratum is clearly a higher-altitude derivative of the form of subsp. hypericoides that occurs at lower levels in the Dominican Republic. Although there is a region between 1600 and 2000 m where both subspecies are present, there appears to be little morphological overlap between them. Some specimens of subsp. prostratum have been determined as H. constanzae Urban, but this is a synonym of H. diosmoides Griseb. (sect. 29. Brathys), see Robson (1990: 37).
