where they were until the newly appointed curator of botany at the Swedish Acad- 

 emy, Professor C. A, M. Lindman/° discovered them among other bundles of 

 plants stored away in "lumber rooms.'^ These collections consist of the herbaria of 

 Carl von Linn£ fil., Alstroemer, Montin, and Solaxder, and contain many 

 specimens named by Linnaeus himself. These plants of Linnaeus and his son, and 

 from Hortiis Upsaliensis during the lifetime of Linnaeus, aggregate about 2000, 

 They have been brought together as a ''Herbarium Linnaeanum/' and Lindman 

 is now publishing a list of the species, arranged according to SysL Veget. ed. 13 

 (1774) and SuppL Plant. (1781). — ^Theo. Holu. 



Climate and plants. — ^H. von Guttenberg^^ has made an anatomical and 

 physiological study of tlie evergreen element of the Mediterranean flora, in part 

 quite parallel to the studies which Bergen has published in this journal and to 

 some extent upon the same species. His work, however, was more extensive. 

 It was done upon two islands, Lussin and Brioni Grande, near the Austrian coast 

 of the Adriatic, and while his results as to transpiration do not always agree with 

 Bergen's, their general drift is the same. The anatomical structure of the leaves 

 is not of the extreme xerophilous type, because these plants must be able to take 

 advantage of the more favorable conditions of spring and autumn, as well as to 

 withstand the drought of summer. Thus, he finds the guard cells characterized 

 by a special motiUty because of the "hinge" in the wall, so that they can prevent 

 transpiration almost entirely by complete closure or allow it freely by wide open- 

 ing. We may pe permitted some skepticism as to the perfection of this regulation, 

 however. — C. R. B. 



Anatomy of lianes.^FRiES^^ describes the anatomy of the stem and the 

 aerial roots of a cucurbit, Siolmatra hrasiliensis^ with some notes on the mode of 

 origin and form of the aerial roots of a species of Cissus, both occurring in the 

 rain 'forests of northern Argentina and southern Bolivia. Only two cases of the 

 formation of aerial roots have been described among Cuciurbitaceae, and in these 

 the roots are small and known only in house-grown plants. But Siolmatra pro- 

 duces the long ropedike roots, reaching down from the tops of the highest trees, 

 where the plant expands its foliage, to enter the ground and branch profusely.
