Porandra microphylla Y. Wan, is a new recorded species for the flora of Vietnam. This species was collected from Lai Chau and Vinh Phuc province of the country. Morphologically, is closely related to Porandra scandens . Hong, but differs by its smaller and abaxially glabrous leaves and oblong or subglobose anthers. | Porandra TAP CHI microphylla SINH HOC Y.

Hong (Commelinaceae) was firstly described from China [3] based on two species (Thitimetharoch et al. 2003). While studying the genus in Thailand, Thitimetharoch et al. (2003) reported three species from the country, namely P. microphylla, P. ramosa and P. scandens [6]. They also reported distribution of P. scandens in Vietnam [5]. During our scrutiny of the unidentified specimens housed in the herbarium of Institute of Ecology and Biological Resources (HN), we came across two accessions of Porandra which after careful examination of the morphological characters, identified as P. microphylla Y. Wan. This species was never been recorded from Vietnam, hence we are reporting this as a new record to the country. P. microphylla is closely related to P. scandens [2, 3] but it can be differentiated from the later in having oblong or subglobose anthers; .
