Abstract
Plants of aquatic weed quillwort are described from central india (Madhya Pradesh) possessing hitherto unknown features on megaspores. About 10% megaspores show spiny outgrowth (s) on a pyramidal area at the proximal face extending in wider perispore besides large round tubercles. Some of the megaspores also exhibit single large tubercles showing centrally placed "nipple" like projection and still other spores having an identically placed depression or pit on the tubercle. Apart from these features I. fuchsiisp. nov is comparable to onlyI. pantii and I. tuberculata l. fuchsii shows 2n=60 chromosomes in root tip mitosis.
Keywords: Relatives of Isoetes pantii, spiny spores in lycophyta New species of lsoetes
