Indian Cheilanthoid fern - A numerical taxonomic approach

A dihydroflavonol with taxonomic significance from the fern Notholaena sulphurea.

A new flavonoid, 2,3-trans-5,2'-dihydroxy-7,8-dimethoxy-dihydroflavonol-3-O-acetate, was isolated from the farinose coating on the lower leave surface of the fern, Notholaena sulphurea. The 2,3-cis diastereoisomer was isolated as a co-constituent. This novel acylated flavonoid is characteristic for the chemotype of N. sulphurea exhibiting yellow frond exudate. Its orrurrence underlines the affi...

Recent Taxonomic Changes for Oregon Ferns and Fern Allies

Readers of Kalmiopsis were recently treated to a synopsis of taxonomic changes affecting flowering plants in Oregon (Chambers, 1992). The present article has been written to update readers on nomenclatural changes recently proposed for the seedless vascular plants, which include not only ferns, but also horsetails, club-mosses, and their relatives. Together these groups are often referred to as...

A Numerical Taxonomic Study of Some Pseudomonas-like Marine Bacteria

The abilities of 26 marine and 12 other Pseudomonas-like strains of bacteria to grow on single carbon sources, their antibiotic sensitivities and complement of some enzymes of intermediary metabolism were numerically analysed and gave five phenons. Two phenons contained strains with more than 55 mol % GC and were regarded as Pseudomonas spp., two were similar to the genus AZteromonas, and one w...
