Closeup of the species.
Species name: Marsilea minuta

Marsilea minuta is a highly plastic and variable pteridophyte. Other species, namely, M. brachycarpa, M. brachypus, M. gracilenta and M. maheshwari also fall within the range of variation and probably are different environmentally induced phenotypes (Cook). All Marsilea species are found in Africa and in India highlighting the fact that India was once upon a time connected to Madagascar.

General morphology

Parameter Value(s) References
See complete references in the References section at the end
General morphological features of the plant The plant is highly variable. It appears cushion-like on dry lans, but in water is spreading and creeping. Internodes 0.5-20cm long. Petioles 2-8cm long on land and upto 25 cm or more in water. Leaflets a maximum of 2.5 cm. Sporocarp stalks simple, numerous, arising one above the other near base of leaf stalk. These sporocarps are usually crowded and in groups of 2-3.

All Marsilea species possess creeping or floating stems/ The leaves are spirally rolled when young. The petioles terminate in four leaflets. The margin of leaves is entire when growing in water, but when they encounter dry climate, the margins become crenate or toothed. Sporangia are in closed sporocarps, borne on short stalks on the petioles.."The plant is highly variable. It appears cushion-like on dry lans, but in water is spreading and creeping.

Seed dispersal mechanism
Bloom type Annual, Perennial Cook
Life cycle of the plant It is a tenagophyte. Juvenile usually submerged, adult is terrestrial. The plant is perennial, but sometimes annual.

In different Marsilea species, the adult can be floating, emergent or terrestrial. Plants usually require an emergent period to develop sporocarps. The sporocarps may remain viable for over a hundred years and may get reactivated after passing through a duck.

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:
  1. Studies on single genes, where people try to sequence genes such as some specific dehydrogenases important,say, for tannin production
  2. Sequences of Ribosomal Internal Transcribed Spacer, whose sequence is used for generating molecular phylogenetic trees to establish species relationships
  3. 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
