Linntcan Societg. 25 'I sccond division (from page 21 to p. SO.) is entitled ' Commentatio de Salicibus Suecia.' Under Scirpus niulticaulis, Sm., is given a very detailed account of the mode of growth and structure of that plant and of Sc. palustris, paucijlorus, and cespitosiu. A ncm species of Cuscuta, considered as intermediate between C. europcea and epilinon, which has been discovered by hlr. Blyth of Christiania, parasitical upon Chciiopodiacea: on the sea-shore of Nonvay, is described
more » ... ay, is described under the name of <' C. halophyta, mule simplici, florum glomerulis multifloris subbracteatis, corollm tubo globoso limbum mquante." We. havc seen specimens of this plant from Norway in the Herbarium of hIr. R. I3. Bowman of Newcastle, and it is much to bc wished, that that gentleman, or somc other botanist, who may havc the opportunity, would esaminc thc structure of the scales in the interior of the corolla, as no notice is taken of that part by Fries. Zmnichellia pedunculata and polycarpa are separated from Z. pa-Zusfris : the former we suspect is only a varicty, but the latter appears to be a good species, cliaractcrized by its very short styles. I n the ' Commentatio de Salicibus' our author first endeavours t o determine the species contained in ' Linn. F1. Lapp.' and then proceeds to1cnumcrate and describe all the Swedish species; and the synonyms of Linnms, Smith, Willdenow, Wahlenberg, and Iiocli arc quoted throughout. It ~o u l d occupy too much of our space to go i n detail through this part of tlic book beforc us, nor indeed is i t at all necessary, as we. doubt not that it will soon be in tlic hands of all students of this very difficult genus. A new number of Reichenbach's ' Icones Florm Germanica' has just reached us : it contains 23 platcs, figuring 56 species and viirietics of German Violets. The plates arc csccuted with tlic usual care, and will bc found most useful in determining the different forms i n this genus. PROCEEDINGS OF LEARNED SOCIETIES.
