Celastrus paniculata (c. multiflora and c. mutans) is a large climbing shrub found in the hilly districts of India, Burma and Ceylon. The seeds, leaves and an oil extracted by distillation are used in Ayurvedic medicine and are believed to increase intelligence. The Sanskrit name Jyotishmati or “light-bringer” is an allusion to this reputed property. Other members of the family Celastraceae, notably Gymnosporia deflexa Sprague and Catha edulis Forsk, are favoured by the natives of Africa as mental stimulants (Watt and Breyer-Brandwijck, 1932).

AbstractThis article deals with the impact of legal rules on incentives in the seeds sector to create new plant varieties. The first category of rules consists in intellectual property rights and is intended to address a problem of sequential innovation and R&D effort. The second category concerns commercial rules that are intended to correct a problem of adverse selection. We propose a dynamic model of market equilibrium with vertical product differentiation that enables us to take into account the economic consequences of imposing either Plant Breeders’ Rights (PBRs) or patents as IPRs and either compulsory registration in a catalog or minimum standards as commercialization rules. The main result is that the combination of catalog registration and PBRs adopted in Europe is hardly supported by the model calibrated on data for wheat in France.

A Pilot experiment by Weber (1950) established the fact that the minor skeletal variations universally present in strains of tame mice are also encountered in wild populations; and that the incidence of individual variants may differ widely from population to population. In the decade since Weber's work many new variants have come to light, and it seemed desirable to repeat his observations on the more extensive range of variants now available. An opportunity to do so presented itself in 1956 when wild mice from various localities in the eastern U.S.A. became available for study. These animals had been collected for a totally different purpose. As is well known through the work of Dunn and his collaborators, there exists in the mouse a semi-dominant gene (T) for Brachyury or short-tail which in T/+ heterozygotes shortens the tail to a varying extent.
