Species name: Isoetes coromandelina
The genus Isoetes consists of more than 130 species. Fourteen endemic species have been described in India. The ranges of most of these species overlap each other, and there's no consensus about their specific limits. This entry, thus, may encompass information about more than one species and inter-species hybrids.

General morphology
| Parameter | Value(s) | References See complete references in the References section at the end |
|---|---|---|
| General morphological features of the plant | Quillworts are mostly aquatic or semi-aquatic in clear ponds and slow-moving streams, though several (e.g. I. histrix, I. nuttallii) grow on wet ground that dries out in the summer. Quillwort leaves are hollow and quill-like, arising from a central corm. Each leaf is narrow, 2-20cm long (exceptionally up to 100cm) and 0.5-3mm wide; they can be either evergreen, winter deciduous, or dry-season deciduous. They broaden to a swollen base up to 5mm wide where they attach in clusters to a bulb-like, underground rhizome characteristic of most quillwort species, though a few (e.g. I. tegetiformans) form spreading mats. This swollen base also contains male and female sporangia, protected by a thin, transparent covering (velum), which is used diagnostically to help identify quillwort species. They are heterosporous. Quillwort species are very difficult to distinguish by general appearance. The best way to identify them is by examining the megaspores under a microscope"Quillworts are mostly aquatic or semi-aquatic in clear ponds and slow-moving streams, though several (e.g. I. histrix, I. nuttallii) grow on wet ground that dries out in the summer.

| Details about the habitat | Isoetes is usually found in aquatic environments and moist soils. They grow solitary or gregarious, in open or closed vegetation, growing near edges of small ponds and lakes. Often locally dominant and can form extensive stands.
The distribution of I. coromandelina is hard to define due to difficulties in taxonomic delimitation. Under certain classification schemes, it is classified as endemic to the Indian subcontinent |

Pubmed Word cloud
This word cloud is obtained using the tool LigerCat by searching the Pubmed database. LigerCat builds the cloud from the most relevant Medical Subject Headings (MeSH) terms. Each term's relative size indicates how many times it appears in the PubMed search results. Click on a term to access the full LigerCat cloud, with live PubMed search capabilities. LigerCat has been developed for the Biology of Aging Project.
The page may take some time to load since LigerCat is searching the entire PubMed database and sending us the results in real time.
- If there is an error message below, it means that there is no retrievable information available on NCBI
- If the number of nucleotide sequences is less than 100, very little genomic work has been done on this species. A respectable number of nucleotide sequences is above 10000.
- Most of the nucleotide sequences may come from three sources:
- Studies on single genes, where people try to sequence genes such as some specific dehydrogenases important,say, for tannin production
- Sequences of Ribosomal Internal Transcribed Spacer, whose sequence is used for generating molecular phylogenetic trees to establish species relationships
- Expressed Sequence Tags (ESTs) which can tell about which genes are present and expressed in the species at a particular time in the given tissue

| Details of modern scientific knowledge available for this species | Under submerged conditions, Isoetes species have been reported to use the Crassulacean Acid Metabolism pathway for carbon assimilation, just like desert plants. (Kramer)
Isoetes roots have been found to be associated with fungal species which form bunches of intracellular hyphae in cortical cells of young roots.Such associations are not dependent on habitat (Sharma) The various species may also exist as inter-species hybrids with highly variable chromosome numbers. One species - I. sampathkumaranii - has been shown to be a hexaploid. Some American species are decaploids (Kramer) |
