Spore morphology of Haplopteris C. Presl species (Vittarioideae, Pteridaceae) from China

New Sulphated Flavonoids from Wissadula periplocifolia (L.) C. Presl (Malvaceae).

Wissadula periplocifolia (L.) C. Presl (Malvaceae) is commonly used in Brazil to treat bee stings and as an antiseptic. The antioxidant properties of its extracts have been previously demonstrated, thus justifying a phytochemical investigation for its bioactive phenolic constituents. This has yielded five new sulphated flavonoids: 8-O-sulphate isoscutellarein (yannin) (1a); 4'-O-methyl-7-O-sulp...

Bioactive Constituents from Aerial Parts of Thymus longicaulis C . Presl

Thymus longicaulis C. Presl., belonging to the Lamiaceae family, is a small aromatic perennial herb typical of the Mediterranean vegetation. This species, known in traditional phytoteraphy of Italy, has been extensively investigated in terms of chemical analysis and biological activity of its essential oils. Nevertheless, few data are available in the literature, regarding the chemical characte...

Review of the spore-feeding Idolothripinae from China (Thysanoptera, Phlaeothripidae)

An illustrated key is provided to the 19 genera of the subfamily Idolothripinae from China, and a checklist given to 62 named species, of which six species are newly recorded from China, together with the genus Bolothrips that is represented by two un-named species. A generic diagnosis is given for each genus, along with some discussion of systematic relationship problems and species diversity....

The shape of fungal ecology: does spore morphology give clues to a species' niche?

Electron microscopy of Streptomyces spore morphology and its role in species differentiation.

The widespread search for new antibioticproducing Streptomyces unleashed during the last two decades also brought with it the problems of their classification. In the early attempts at species differentiation excessive use was made of highly variable cultural and physiological properties as taxonomic criteria and too little attention was paid the more stable morphological characteristics. Howev...
