Ravenelia species (Pucciniales) newly found in Thailand with their additional host and life cycle stage

Three poorly known species of Ravenelia with limited geographic distribution and one widespread species parasitizing leguminous trees (Fabaceae) were newly found in Thailand. Ravenelia odoratissimae occurred on Albizia odoratissima; R. ornata on Abrus pulchellus, Ab. precatorius, and Abrus sp.; R. parasnathii on Acacia comosa and an unidentified Acacia species; and R. tandonii on Acacia catechu. Acacia comosa is a new host for R. parasnathii. Detailed morphological study revealed that R. odoratissimae produces a uredinial stage in addition to a telial stage in its life cycle
