The present investigation deals with the ethnomedicinal plants of Kumaragiri Hills of Salem district, Tamilnadu. The indigenous knowledge of the village dwellers, the herbal medicine practitioners and other traditional healers and the native plants used for medicinal value were collected through questionnaire and personal interviewed during field trips. The study revealed some unknown medical u...

The phrase “Darwin’s abominable mystery” is frequently used with reference to a range of outstanding questions about the evolution plant group today known as angiosperms. Here, I seek more fully understand what prompted Darwin coin in 1879, and meaning he attached it, by surveying systematics, paleobotanical records, phylogenetic hypotheses his time. In light this historical research, argue tha...

Surveys of plant breeding systems in angiosperm families have shown a significant association between monoecy and dioecy, and researchers have proposed that dioecy has tended to evolve from monoecy. We evaluated this hypothesis in the context of a phylogeny of 918 monocotyledons assembled from 19 published trees. Binary and multistate breeding system characters were mapped onto a set of composi...

Main aims of the study are a deepened understanding of the mechanically relevant (ultra-)structures and the mechanical behaviour of various arborescent and shrubby monocotyledons and obtaining the structure-function relationships of different structurally conspicuous parts in Dracaena marginata stems. The stems of five different "woody" monocotyledon species were dissected and the mechanical pr...

Within monocotyledons, monosulcate pollen is the predominant type and probably represents the plesiomorphic condition, but considerable variation occurs in sulcus morphology. An operculum is an exine thickening that covers most of an aperture. Monocot opercula are usually associated with sulci, although they can occur in ulcerate apertures, as in Poaceae. There are several other aperture types ...
