58 NOTICES OF BOOKS AND MEMOIRS. 



insertion without any mark of uncertainty throws some doubt on 

 the correct naming of the more critical plants in the catalogue. 

 It may be questioned also whether the use of initials presents any 

 advantage that can compensate for the inconvenience of effectually 

 disguising the relative value of assertions thus authenticated.

In the 23rd part of the ' Symbolae ad fl. Brasil. central, cognos- 

 cendam,' published in the Copenhagen Natural History Society's 

 Journal for last year, Mr. Hiern enumerates the Solanacea^ , Acan- 

 thacecB, Gesneracem, and VerhenacecB. He has been unable to avoid 

 adding seven new species to the already gigantic genus Solcmum, 

 and there are about a dozen previously midescribed species in the 

 other genera contained in the orders enumerated above. 



Prof. Maximowicz, in a second portion of his Diagnoses Plant. 

 Nov. Asiatic. ('Mel. Biologiques de St. Petersbom-g,' x. 1877), 

 describes several new Chmese and Mongolian sj)ecies of Corydalis, 

 and gives monographic revisions of the East Asiatic species of 

 Lonicera (thnty) and Pedicularis (fifty). Dipelta, gen. nov., fi-om 

 China, is also here described ; it occupies a position between Sym- 

 phoricarjnis and Abelia. 



Prmgsheim's ' Jahrbuch fiir Wissenschaftl. Botanik ' for 1877 

 contains memoirs on morphology, chiefly of dichotomous inflo- 

 rescences, by H. Wydler ; on the primitive meristem of Dicoty- 

 ledonous roots, by J. Eriksson (with ten plates) ; and on the force 

 of pressm^e in the stem m the phenomena of ' bleeding ' and 

 * weex^ing.' 



In Cohn's ' Beitrage,' for 1877 (Bd. ii. heft 3) are papers by 

 L. Just, on the influence of high temperatures on the capacity for 

 germination of seeds ; by Schroeter, on the UstilaginecB (t. 13) ; and 

 by Koch, on Bacteria (tab. 14-16). We defer a full notice. 



In the * Linnaea ' (vol. vii. pts. 5 & 6, dated October, 1877), 

 E. Goeze concludes his interesting account of the vegetation of 

 Portugal, and H. Polakovsky enumerates the Phanerogams of 

 his Costa Eica collections, of which the Cryptogams were cata- 

 logued in this Journal last year.
