THE most recent numbers of Trimen's Journal of Botany (224-232) run rather strongly on phanerogamic, descriptive and geographical botany. The diligence of English observers seldom fails to add two or three species to the British flora every year, either by absolute discovery, or by the separation of well-marked varieties. Three of these are described and figured in the numbers before us, viz. Spartina Townsendi, Groves, Agrostis nigra, With., and Senecio spathulœfolius, DC. There are various other descriptions of critical forms, and papers on the flora of English districts or of foreign countries; also on British Charaeeæ, and on marine Algæ new to Devon and Cornwall. Among the more interesting illustrations are two coloured plates of Cinchona Ledgeriana, a new species described by Dr. Trimen. —The number for April, 1882, contains an interesting paper by C. P. Hobkirk, on the development of Osmunda regalis from the prothallium, and several contributions to the extended controversy on the principles of botanical nomenclature.
