Sirodotia iyengarii Baluswami & Babu

Baluswami & Babu 1999a, p. 238, figs 1–18.

Distribution in India: Kerala (Nilambur hill stream, Malappuram district near Coimbatore city. Feb. & Jun.).

Notes: Sirodotia iyengarii , although validly described and published, was not included in Kumano (2002), presumably because the generic assignment for Indian species is unclear. Some features viz., (i) twisted or contorted carpogonial branches (a diagnostic character of Kumanoa ) (ii) gonimoblast developing from the hypogynous cell and not from the fertilized carpogonium and (iii) diffuse or compact nature of the carposposporohytes warrant a reinvestigation of the Indian specimens. In all species of Sirodotia , it has been clearly demonstrated that the carpogonium has a “definite basal protrusion” and indeterminate carposporophyte composed of creeping and erect gonimoblast filaments ( Kumano 2002, Sheath 2003, Necchi 2016).

Another important point is that a recently described genus Volatus ( Chapuis et al. 2017) has characteristics of the two genera Kumanoa and Tuomeya .
