A new species of Adiantum is described from California. This species is endemic to northern California and is currently known only from Shasta County. We describe its discovery after first being collected over a century ago and distinguish it from Adiantumjordanii and Adiantumcapillus-veneris. It is evergreen and is sometimes, but not always, associated with limestone. The range of Adiantumshas...

Ind.: 310. 1825), has long been applied to a species widely distributed tropical Southeast Asia, including India (Andaman Isl...

Premise Recent studies of plant RNA editing have demonstrated that the number sites can vary widely among large taxonomic groups (orders, families). Yet, very little is known about intrageneric variation in frequency editing, and no study has been conducted ferns. Methods We determined plastid RNA-editing counts for two species Adiantum (Pteridaceae), A. shastense aleuticum, by implementing a p...

When filamentous protonemata of Adiantum capillus-veneris L. precultured under continuous red light were transferred to the dark, the apical cell divided about 24 to 36 hours thereafter. The time of the cell division was delayed for several hours by a brief exposure to far red light given before the dark incubation. The effect of far red light was reversed by a small dose of red light given imm...

By quantitative techniques it has been shown that the expected tumor frequency after x-irradiation of spores of the fern Pteridium aquilinum can be reduced by the addition of casein hydrolyzate or amino acids to the medium upon which the spores are germinated and grown into either prothalli or tumors.

Background and objectives: Maidenhair fern is an herbal medicine belonging to the family Pteridaceae which is extensively found in Atlantic coast as far as Ireland, America and Iran. The fronds of Adiantum capillus-veneris are prescribed for treatment of different diseases. Different phytochemical compositions such as flavonoids, alkaloids, tannins, terpenoids, etc...
