Species name: Ceratopteris pteridoides
Ceratopteris species are aquatic pteridophytic ferns, generally found in tropical regions. They require a warm climate and lots of water. Two species - C. pteridoides and C. thalictroides are found in India. There is confusion among botanists on whether Ceratopteris cornuta and C. pteridoides are separate species.

General morphology
| Parameter | Value(s) | References See complete references in the References section at the end |
|---|---|---|
| General morphological features of the plant | Plants floating or rooted. Sterile leaves deltate to cordate to ovate. Petiole of sterile leaf 1--19 cm, usually inflated, in some near base, but in most inflated nearer blades. Blade of sterile leaf 2--4-pinnate, 5--33 × 4--29 cm, simple and palmately 3-lobed (ternate), or pinnately 5-lobed or pinnate near base; proximal pinnae or veins of lobes usually opposite. Fertile leaves deltate to cordate to reniform, 9--50 × 8--36(--50) cm. Petiole of fertile leaf 4--25 cm. Blade of fertile leaf 1--4-pinnate; terminal segments narrow, linear. Sporangia usually crowded between segment midvein and revolute margin, with 0--10(--40) indurate annulus cells. Spores 32 per sporangium, 70--100 µm diam. 2 n = 78.
Ceratopteris pteridoides is usually easily recognized by its sterile leaf morphology, which varies considerably with habitat. Leaves intermediate between sterile and fertile are fairly common, with various degrees of laminar development of the fertile segments. Some fertile leaves have quite broad segments with rows of sporangia along the margins only. Ceratopteris pteridoides is sexual and diploid and is incompletely reproductively isolated from the diploid C . richardii . Hybrids synthesized by L. G. Hickok (1977) result in 40% viable spores."Plants floating or rooted. Sterile leaves deltate to cordate to ovate.

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.

- 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
