C0C8517B158A9068D479626F3E7020E5.taxon	etymology	Etymology. The specific epithet ' manasiae ' honours the late Dr. Manasi Ram nee Ghosh for her contributions to the study of embryology and systematics of Santalaceae (Ghosh 1956) and Trapa L. (Lythraceae; Ghosh 1954).	en	Krishnan, Remya, Khanduri, Priyanka, Tandon, Rajesh (2019): Zeylanidium manasiae, a new species of Podostemaceae based on molecular and morphological data from Kerala, India.

C0C8517B158A9068D479626F3E7020E5.taxon	distribution	Distribution and ecology. Zeylanidium manasiae is highly endemic and is known from only one location so far, i. e. Thommenkuthu waterfalls (Figs 1 and 3 A). According to a previous report, rocks of this waterfall are hornblende biotite gneiss type (Girija 2008). According to Mathew and Satheesh (1996), water in Kaliyar River is well-oxygenated hard water with low chloride content. Zeylanidium manasiae grows along with Z. lichenoides and Z. sessile. Diatoms (Cymbella C. Agardh species) were also observed forming colonies on the spathella of some of the plants.	en	Krishnan, Remya, Khanduri, Priyanka, Tandon, Rajesh (2019): Zeylanidium manasiae, a new species of Podostemaceae based on molecular and morphological data from Kerala, India.
