Linncean Society. 25? second division (from page 21 to p. 80.) is entitled ' Commentatio de Salicibus Suecise.' Under Sar/?M5 multicaulis, Sm., is given a very detailed account of the mode of growth and structure of that plant and of Sc. palustris, pauciflorus, and ccespitosus. A new species of Cuscuta, considered as intermediate between C europcea and epilinon, which has been disco-vered by Mr. Blyth of Christiania, parasitical upon Chenopodiacece on the sea-shore of Norway, is described under the name of ** C. halo-phyta, caule simplici, florum glomerulis multifloris subbracteatis, co-rollse tubo globoso limbum sequante." We have seen specimens of this plant from Norway in the Herbarium of Mr. R. B. Bowman of Newcastle, and it is much to be wished, that that gentleman, or some other botanist, who may have the opportunity, would examine the structure of the scales in the interior of the corolla, as no notice is taken of that part by Fries. Zannichellia pedunculata and polycarpa are separated from Z. pa-lustris : the former we suspect is only a variety, but the latter ap-pears to be a good species, characterized by its very short styles. In the 'Commentatio de Salicibus' our author first endeavours to determine the species contained in ' Linn. Fl. Lapp.' and then pro-ceeds to'enumerate and describe all the Swedish species; and the syn-onyms of Linnaeus, Smith, Willdenow, Wahlenberg, and Koch are quoted throughout. It would occupy too much of our space to go in detail through this part of the book before us, nor indeed is it at all necessary, as we doubt not that it will soon be in the hands of all students of this very difficult genus. A new number of Reichenbach's * Icones Florse Germanicae' has just reached us ; it contains 23 plates, figuring 56 species and va-rieties of German Violets. The plates are executed with the usual care, and will be found most useful in determining the diflferent forms in this genus. PROCEEDINGS OF LEARNED SOCIETIES. LINN^AN SOCIETY.
