The river-weed family Podostemaceae (c. 300 species in c. 54 genera) shows a number of morphological innovations to be adapted to its unusual aquatic habitat, and its unique or rare bauplan features have been reflected in the traditional (i.e. non-molecular) classification recognizing numerous monotypic or oligospecific genera. The infrasubfamilial relationships of many genera remained unclear. The present study used molecular phylogenetic analysis of matK sequences for 657 samples (c. 132 species/c. 43 genera). The family was traditionally divided into three subfamilies (Podostemoideae, Tristichoideae and Weddellinoideae). American Podostemoideae were shown to be polyphyletic and divided into four clades, i.e. Ceratolacis, Diamantina, Podostemum and all other genera. Among the podostemoid clades, Diamantina was the first branching clade and a clade comprising Mourera and the Apinagia subclade was then sister to the remainder of the New World and Old World Podostemoideae with low statistic supports. The Old World Podostemoideae comprised four monophyletic clades, i.e. two African clades, one Madagascan clade and one Asian clade, although the relationships among these clades and American Ceratolacis and Podostemum were poorly resolved. African Podostemoideae were polyphyletic, with Saxicolella pro parte being weakly supported as sister to the remaining Old World Podostemoideae plus Ceratolacis and Podostemum. In contrast to the American and African clades, monophyly of four Asian subclades was well supported. Plants of Tristicha (Tristichoideae) and of Weddellina (Weddellinoideae), which are currently treated as monospecific, had great matK differentiation equivalent to at least interspecific variation.

“…The Asian genus Polypleurum comprises at present 16 species distributed in Thailand, Vietnam, China, Japan (Kato, 2004(Kato, , 2006, Sri Lanka and India (Mathew and Satheesh, 1997;Mathew et al, 2003;Nagendran, 1975;Willis, 1902). Three species of Polypleurum of India and Sri Lanka are the subject of the present investigation: P. stylosum (Wight) Hall, P. elongatum (Gard.)…”

“…Anatomical data of roots of P. elongatum are provided by Koi et al (2006). Polypleurum minus (grammatically incorrectly called P. minor in Mathew et al, 2003), was first described by Weddell (1873, as Dicraea minor), but has not been subject of more detailed studies in the meantime.…”
