Dalzellia gracilis, an enigmatic species of Podostemaceae, is characterized by the subcylindrical creeping roots\udand dorsiventral ribbonlike shoots borne on the roots. To reveal the phylogenetic relationships of D. gracilis,\udmolecular phylogenetic and morphological analyses were performed. A matK tree indicates that it is most likely\udsister to a clade of its congeners and Indotristicha ramosissima. Dalzellia gracilis, like Tristicha, has subcylindrical, roots, and it exhibits an endogenous developmental pattern in both shoots and associated\udholdfasts shared byTerniopsis, Indotristicha, andTristicha. The dorsiventral ribbonlike adventitious shoots, with\udthe dorsiventral compressed shoot apical meristem producing dimorphic leaves on the dorsal and ventral-lateral\udsides, are extremely similar to the crustose shoots of the other species of Dalzellia. Dalzellia gracilis is devoid of\udrosettes, although the other congeners have them. The many free leaves subtending the base of the pedicel are also\udunique to the species, whereas the trimerous flower is common to subfamily Tristichoideae. On the basis of these\udmolecular and morphological results, we describe a new genus Indodalzellia for D. gracilis to draw attention to\udthese morphological distinctions. Dalzellia, Indodalzellia, and Indotristicha have remarkable morphological\uddifferences compared to the inconspicuous morphological diversity in Tristicha and Terniopsis and between the\udtwo genera
