DISTRIBUTION. — Widely distributed, occurring in Mexico, throughout Central and South America in Colombia, Peru, Bolivia, Venezuela, Brazil (Robertson 1971), Guyana and Argentina. It grows in other open, non forested habitats. REMARKS <i>Jacquemontia sphaerostigma</i> has herbaceous habit and climbing stems, dense inflorescences and four distinct types of trichomes: stellate 3-radiate with subequal rays; stellate 3-radiate with unequal rays; forked (rarely simple); and glandular trichomes(Fig. 2). With the similar indumentum to <i>J. evolvuloides</i>, <i>J.sphaerostigma</i> is distinguished with basis on its umbelliform to corymbiform dichasium, while <i>J. evolvuloides</i> has lax monochasial. Choisy (1838) observed that <i>Convolvulus sphaerostigma</i> Cav. should be transferred to <i>Jacquemontia</i> but he renamed it as <i>J. hirsuta</i>, creating an illegitimate name. Rusby (1899) subsequently made the correct combination. We considered <i>Jacquemontia laxiflora</i> as synonym of <i>J.sphaerostigma</i> because slightly lax inflorescence, non-glandular trichomes, and corolla 12-15 mm long are characters also found in some specimens of <i>J. sphaerostigma</i>.
