Prof. Lehmann of Hamburgh is engaged upon a new and ful- 
ler monograph of Potentilla, a genus upon which he has written 
so much, and of which he has accumulated the amplest materials. 
Meanwhile he has given, in his ninth Pugillus Novarum et Mi- 
nus Cognitarum Stirpium (1851), a revised arrangement, with 
a complete catalogue and synonymy of all the species at present 
known, 193 in number. 
Dr. Blume, the director of the Royal Herbarium at Leyden, 
having finished the Rumphia (in four folio volumes, with 213 
plates) is making arrangements to resume his Flore Jave, which 
was interrupted in 1829, with the third volume. He also began 
in 1849, and continues in monthly fasciculi, each of 16 pages 
8vo, the “Museum Lugduno-Batavum, sive Stirpiun Erotica- 
rum Novarum vel minus Cognitarum ex vivis aut siccis brevis 
Ecpositio et Descriptio, additis figuris.” Each number is accom- 
panied by one plate, giving the detailed generic characters of 
from two to four plants. Different families or groups are taken 
up in succession, and more or less revised or monographed. _ 
Professor DeVriese, who now has the botanical chair in the 
University, and the direction of the fine old botanic garden of 
Leyden, and Prof. Miquel, who holds the same position at Am- 
sterdam, besides other important scientific undertakings, are work~ 
ing up the large collections recently brought by Junghuhn from 
the Dutch East India possessions, assisted by several collabora- 
tors (Mr. Bentham taking the Leguminose, etc.): the first fas- 
ciculus of the Plante Junghuhniane has already appeared, and 
probably the second also. ° 
Drs. Dozy and Molkenboer, two physicians of Leyden, occupy 
their leisure with the Muscology of the Dutch Colonies. 
Last year Sir Wm: Hooker, in conjunction with Professor 
Arnott of Glasgow, issued a new (the sixth) edition of the Brit- 
sh Flora, which by the use of small type is brought down from 
the 8vyo to a compact 12mo size. And Mr. Babington has this 
year bronght out a third and revised edition of his Manual of 
ritish Botany. These two works ably represent the rival 
schools; the one strongly inclined to combine and reduce, the 
other to distinguish species. et get >
