If genetic constraints are important, then rates and direction of evolution should be related to trait evolvability. Here we use recently developed measures of evolvability to test the genetic constraint hypothesis with quantitative genetic data on floral morphology from the Neotropical vine Dalechampia scandens (Euphorbiaceae). These measures were compared against rates of evolution and patter...
Abstract Eight new anamorphic species of Pucciniales belonging to the genera Aecidium, Caeoma, Malupa, Milesia, Physopella and Uredo are proposed. The were collected in Itatiaia National Park states Minas Gerais Rio de Janeiro, Brazil, on plant families Annonaceae, Apocynaceae, Euphorbiaceae, Menispermaceae, Salicaceae, Solanaceae Verbenaceae.

The mortality caused to the snail Bulinus wrighti (The snail vector of urinary schistosomiasis) by different extracts of two species of plants belonging to the family Euphorbiaceae has been investigated. It was found that very low concentrations of fresh leaf extracts were effective in killing the snail. The LC50 of methanol and acetone extracts for Euphorbia schimperiana and Euphorbia heliosco...
In the present paper, 46 plant species of angiosperms belonging to 19 genera of Euphorbiaceae that occur naturally in the Tirunelveli Hills of western Ghats, India, were chosen for study. It was found that the uses of Euphorbiaceous plants by the inhabitants of this region cover a number of broad categories including food, various kinds of poisons, medicines, sundry types of oils, waxes, rubber...
The macroscopical characters of the roots, physical constant values, extractive values, colour, consistency and extractive values with different solvents, behaviour on treatment with different chemical reagents, fluorescence characters of liquid extracts and root powder after treatment with different chemical reagents under ultraviolet light of the powdered roots of Tragia involucrata Linn. (Fa...
The present study was designed for phytochemical and antioxidant activity of methanolic extract of the whole plant Euphorbia thymifolia linn. Belonging to the family Euphorbiaceae. It cures many diseases. The phytochemicals present in this methanolic extract were studied by standard Protocols and the invitro antioxidant activities were studied using different methods i.e., H2O2 scavenging activ...
The methanol extracts from five different plant families (Asteraceae, Euphorbiaceae, Melastomataceae, Rubiaceae, and Solanaceae) collected at Regional Natural Park Ucumarí (Colombia), were screened for their acetylcholinesterase inhibitory activity through the modified Ellman's spectrophotometric method. The best inhibitory activities on this study were shown by the extracts of Solanum leucocar...
Ricin is a toxic glycoprotein (with several minor variants) belonging to the type II group of ribosome inactivating proteins (type II RIP) found in the seeds (beans) of the castor oil plant (Ricinus communis L. (Euphorbiaceae)). It is composed of two polypeptide chains of approximately 30 kDa joined by a disulfide bond. A limited number of other plants in the same family contain type II RIPs, i...
