REMARKS

Jacquemontia warmingii is allied to J.anomala and J.guaranitica , and the distinguishing characters are presented in Table 1 .

Hassler (1911) had already suggested that Ipomoea prostrata Meisn. probably belonged to the genus Jacquemontia , but he did not propose a new combination.When transferring Ipomoea prostrata (1869) to Jacquemontia , O’Donell (1950c) correctly proposed the replacement name J.warmingii (1950) , according to article 11.4 ( Mcneill et al. 2012). The name Jacquemontia was previously occupied by J. prostrata Choisy (1845) .
