Portulacaceae is one of 19 families of terrestrial plants in which species having C(4) photosynthesis have been found. Representative species from major clades of the genus Portulaca were studied to characterize the forms of photosynthesis structurally and biochemically. The species P. amilis, P. grandiflora, P. molokiniensis, P. oleracea, P. pilosa, and P. umbraticola belong to the subgenus Po...

Lectotypes are designated for four species epithets, including one second-step lectotypification, under the family Gesneriaceae Rich. & Juss., viz., Cyananthus umbrosa Griff., Didymocarpus griffithii Wight, Lysionotus pubescens C.B.Clarke and Petrocosmea parryorum C.E.C.Fisch., along with detailed notes on their typification.

Jasminanthes xuanlienensis (Apocynaceae, Asclepiadoideae), a new species from Vietnam is described, illustrated and compared with its five congeners. Jasminanthes xuanlienensis differs distinctly from congeners by the longer peduncles (14-18 cm vs. 4 cm at most in Jasminanthes pilosa and Jasminanthes saxatilis, salmon-pink color of the inner corolla lobes (white or greenish in the other species...

The species of Braunsia Kriechbaumer, 1894 (Hymenoptera, Braconidae, Doryctinae) from China are revised and ten species are recognized. Two new species, B. guangdongensissp. n. and B. shenyangensissp. n., are described and illustrated. B. fumipennis (Cameron, 1899), B. pilosa Belokobylskij, 1986, B. postfurcalis Watanabe, 1937, and B. smithii (Dalla Torre, 1898), are recorded from China for the...

Salicylic acid has one of its characteristics the allelopathic potential. The present paper, is a research quantitative in nature aimed to assess potential salicylic identify best concentration range for other pure substances. bioassays were performed BOD incubator, seeking seedling growth by measuring radicle and hypocotyl length. Each bioassay occurred 12 days. concentrations used were: 1000,...

The present study has been designed to evaluate the liver protective and in-vivo antioxidant role of Ethanolic extract (EtAS) and Ethyl acetate extract (EAAS) of roots of Argyreia speciosa, an important 'rasayana' herb in Indian System of medicine, in CCl(4)-induced hepatotoxicity and oxidative stress in rats. Animals were treated with EtAS and EAAS at doses of 200 mg and 400 mg/kg body weight ...
