been continued in part seven to the Buhiacew ; the Biologia centrali. 

 americcma, tlie botanical part of which is by Hemsley, contains the 

 orders from Eosacew to Loasaccw ; the Flora Bradliensis, fasc. 7G, cou- 

 taiuiiig- Lemnacew by Hegelmaier, and .4rflcea?by Engler, was pubbshed 

 this year, altliough the last-named order had been- in press for some 

 time.' Tournier's Mexicanarum plantarum enumeratio is devoted to the 

 grasses',' and the same w-riter has a paper on the geographical distribu- 

 tion of I^Iexican grasses in the Ann. Sci. Nat., in which he remarks that 

 of the 04:3 species in ^Mexico 371 are peculiar to that country. Adansonia 

 contains a number of papers by Baillou on the development of the flow- 

 ers in Berheridacea', ^Selaginacew, and StyUdiacew. Concerning oriental 

 plants, we have to mention Eegel's Description of Plants from Central 

 Asia, cultivated in the Botanic Garden at St. Petersburg ; Diagnoses 

 plantarum novarum asiaticarum, by Maximowicx, in the Bull. Acad, 

 Imp. of St. Petersburg; Spicilegia Florw Sineiisis, by Hance, in Journ. 

 Linn. Soc. A succinct account of the Japanese flora is to be found in 

 Rein's work entitled Japan, and a short notice of Madagascar plants 

 is given by Baker in Nature. The grasses of New Zealand are described 

 by Buchanan in a Manual of indigenous grasses of New Zealand. The 

 FragmentorPhytograpUie Australia of Baron F. von Mueller has been 

 continued in two parts, and the same writer has issued a fifth decade 

 of Fucalyptographia, a descriptive atlas of the species of Extcalyptus of 

 Australia and the adjacent islands. In the Gardener's Chronicle is a 

 paper on Cinchonas, and a controversy on the subject of species of Cin- 

 chona has been carried on in the Bot. Zeitung by Kuntze and Karsten. 

 There appeared in 1880 the first volume of Botanische JahrbilGher filr 

 Systematih, PflanzengescMchte, und PJlansengeograpMe, edited by Eiigler 

 and issued by Englemann, of Leipzig. The first volume contains a large 

 number of interesting papers relating to phgenogams, amongst which 

 may be enumerated : Beccari^ & PJlanzengeographie des Malayischen ArcU- 

 pels', Focke's Natilrliche Gliederung und die geographische Verhreitung der 

 Gattung Eubus; Buchenau's Verhreitimg der Juncaceen ilber die Erde; 

 Engler's Beitrdge ziir Eenntniss der Aracece and Verhreitung der Gattung 

 Rhus; and Lange's Studien iiher Gronlands Flora. In connection with 

 the distribution of species should be noticed Quelques observations sur la 

 Flore Alpine W Europe, by Bonnier, in which he compares the notes made 

 by him on plants collected in the Carpathian Mountains, the Austrian 

 Alps, and the Tyrolese Alps, and concludes that the constitution of the 

 soil has little to do with the distribution of species, which depends, as 

 De Candolle maintained, on the sums of the temperatures.
