winter; with his own work in the State he is desirous of compiling 
that of others as fully as possible. Any botanists who have 
worked in the State, and who will send the Doctor a list of 
the species they noted there, giving localities, will receive full 
credit, and six copies of the Flora as a return for the kindness.

Monographie du Genre Chrysosplenium. A Franchet. (Nouv. 
Arch. Mus. Hist. Nat. (III) ii. 87-114, Pl. III.-VI.; iii. 
I-32, Pl. 1-7; reprinted). 
In this most beautiful monograph M. Franchet has given a 
detailed account of the fifty-four species of the genus known up 
to the present time, and illustrated nearly all of them on the ac- 
companying plates, which are exquisite lithographs. The sys- 
tematic portion of the work is prefaced by an account of the his- 
tory of the genus from the time of L’Obel (1576), in whose work 
is found the first indication of the European plant as ‘“ Saxifraga 
aurea Lichenis facie et natalibus.” The genus was first established 
by Tournefort. The vegetative and reproductive organs are clearly 
and concisely described, and the geographical distribution re- 
marked upon as mainly Asiatic, five species only occurring in 
America (C. alternifolium, L., C. Americanum, Schwein., and C. 
&lechomifolium, Nutt., in North America, C. Valdivicum, Hook. 
f, and C. macranthum, Hook. f., in Chili and at the Straits of 
Magellan), while but three species are known in Europe. 
The genus divides itself naturally into two sections, Alternifo- 
lia and Oppositifolia. Of the first, our only representative is C. 
alternifolium, L.., which M. Franchet attributes to Alaska, but 
which has been found much further to the south and east (Min- 
nesota, fide Watson and Coulter) ; of the second, the widely dis- 
tributed eastern C. Americanum, Schwein., readily distinguished 
from the western C. glechomifolium, Nutt., by its glabrous seeds, 
those of C. Americanum being covered with white hispid hairs 
of two kinds—the one very slender, the other thick and clavate, 
as is capitally shown in M. Franchet's figure. 
Three Asiatic species are described as new, while a number 
of the others have first been made known by the author in his 
numerous valuable publications on the plants of China and 
Japan. N. L. B,
