＜正＞According to the statistical data of pteridophyte, this paper discussed the species, families and genera source and the distribution of pteridophyte in east Kunlun Mts. of the Qinghai-Xizang （Tibet） Plateau. The ecological condition of pteridophyte in this region has also been preliminarily studied. The author thought that the flora of pteridophyte in east Kunlun Mts. and the adjacent area is young with poor species, simple ecological forms, and small scope of distribution. It converged wide temperate and anti-cold terrestrial species which came from the surrounding floras. This flora is a border distributive district of pteridophyte in China. Among the ecological factors, low temperature is the key factor restricting the growth, development and the formation of the ecological characteristics and the distributive patterns of pteridophyte in the region.

A review of the use of pteridophytes for treating human ailments

The aim of this review was to explore the pharmacological activity of early tracheophytes （pteridophytes） as an alternative medicine for treating human ailments. As the first vascular plants, pteridophytes （aka, ferns and fern allies） are an ancient lineage, and human beings have been exploring and using taxa from this lineage for over 2000 years because of their beneficial properties. We have documented the medicinal uses of pteddophytes belonging to thirty different families. The lycophyte Selaginella sp. was shown in earlier studies to have multiple pharmacological activity, such as antioxidant, anti-inflammatory, anti-cancer, antidiabetic, antiviral, antimicrobial, and anti-Alzheimer properties. Among all the pteridophytes examined, taxa from the Pteridaceae, Polypodiaceae, and Adiantaceae ex- hibited significant medicinal activity. Based on our review, many pteridophytes have properties that could be used in alternative medicine for treatment of various human illnesses. Biotechnological tools can be used to preserve and even improve their bioactive molecules for the preparation of medicines against illness. Even though several studies have reported medicinal uses of ferns, the possible bioacUve compounds of several pteridophytes have not been identified. Furthermore, their optimal dosage level and treatment strategies still need to be determined. Finally, the future direc- tion of pteridophyte research is discussed.

Physiological integration is a major ecological advantage of clonal growth in *** growth is also common in pteridophytes,but almost no study has tested whether clonal integration increases performance in ramets ofpteridophytes in natural populations. To test this hypothesis and also whether the positive effect of integration is greater on smaller ramets,we severed the connecting rhizomes of individual ramets of the common,understory fern Diplopterygium glaucum in an evergreen,broadleaf forest in southeastern *** another experiment,we severed rhizomes around the edges of small plots each containing several ramets. After 19.5 weeks,survival was 100%in intact individual ramets but only 27%in severed ones. Among surviving ramets,final dry mass and lamina mass were also less in severed than in intact ramets,though stalk,rhizome,and root mass and maximum quantum yield of PSII(F/F) were *** ramets with fewer stalk nodes had lower dry mass but were not more affected by severing than ramets with more stalk *** around the edge of plots did not significantly affect the combined final mass of the ramets within a *** conclude that clonal integration can have significant positive effects on both survival and growth of individual ramets of ferns in natural *** work may eventually show that resource sharing is as widespread in rhizomatous species of pteridophytes as it appears to be in rhizomatous angiosperms.
