Dominica: Batali (Ernst 1297, 1408, Hodge 3806), Mome
Daniel in Roseau (Hodge 3892), Roseau Valley (Lloyd 595).
Flowering and fruiting May.
Boerhavia paniculata
Boerhoviu poniculoto L. Richard, 1792105.
Prostrate to decumbent perennials with opposite leaves to 7.5
cm x 5 cm; flowers maroon.
Pantropical weed; along dry west coast of Dominica: Batali
(Chambers 2793). Cabrits (Whitefoord 401 7), Canefield

Recent workers, e.g., Adams (1972:261), treated this as
Boerhavia diffusa Linnaeus. However, Fosberg (1978:4-5)
concluded that B. difusa is endemic to Sri Lanka (possibly also
southern India). Fosberg’s chosen lectotype has been challenged
(see Kellogg in Howard, 1988, 4:177) but not
superseded, so the application of the name remains in question.
Adjanohoun et al. (1985: 145, pl. 111) reported (asB. difSusa)
medicinal uses.
