52 Notices of Botanical Literature. 
Griffith has a paper on the Structure of the Ascidia and Stomata 
of Dischidia, and one On the Impregnation of Dischidia. 
These, with a paper On the Development of Lemanea fluviatilis, 
by Mr. 'Thwaites of Bristol, (now the successor of the lamented 
Dr. Gardner at Ceylon,) belong to the department of Structural 
tany. Dr. Falconer describes Athalamia, a new genus 0 
Marchantice. Dr. Planchon gives a detailed memoir On Meli- 
anthee, a new natural order. And finally Mr. Brown has pub- 
lished his acconnt of that beautiful and perfectly preserved fossil 
fruit ( T’riplosporite, so called from the remarkable development of | 
the spores in threes instead of fours,) which he has for several 
years past shown to those interested in such researches. If. not 
identical, it is certainly very closely related to Lepidostrobus, | 
which is thus demonstrated to be a Cryptogamous plant, allied to 
Lycopodium. An admirable paper of Dr. Hooker’s on the struc: 
ture and affinities of Lepidostrobus, we may add, which arrives - 
at the same conclusion, may be found in vol. ii, part 2, of the 
Temoirs of the Geological Survey of Great Britain, accom: 
panied by one On the Vegetation of the Carboniferous period, a8 ) 
compared with that of the present day, and another On the Struc 
ture of Stigmaria. / ne 
In Cryptogamic botany many new systematic works have ap- 
peared, and nearly all the orders have been newly elaborated. — 
_We know of no proper Species Filicum in progress, except 
Sir Wm. Hooker’s, already noticed. igs. 
The late Prof. Kunze’s supplement to Schkubrs Filices, (Die 
Farnukrauter in koloriten Abbildungen,) has gone only to the 
fourth fasciculus of the second volume, published last spring. . 
The Synopsis Hepaticarum by Gottsche, Lindenberg, and 
Nees von Esenbeck, gives full characters of all the species known 
up to 1847, when the last (fifth) part was published; the whole 
forming an 8vo volume of 834 pages. The genera, as well as 
the species are largely increased ; and the former, 72 in number, 
are disposed in five tribes, . 
A similar work on the true Mosses, the Synopsis Muscorum 
Frondosorum omnium hucusque cognitorum, by Karl Miiller, i8 
by this time almost completed. The latest portion received (thé 
third fasciculus of the second volume,) finishes the great genus 
Hypnum, of which 500 species are described. 
The latest part of the admirable Bryologia E'uropea, with the 
authorship of which the name M. Giimbel is lately associated, 18, 
[ believe, the 42nd (1849). And Dr. Schimper has lately pub- 
lished in the Mémoires de la Société @ Hist. Nat. de Strasbourg; 
an elaborate paper on the anatomy and development of Mosses. — 
Kiitzing’s Species Algarum (1849) has been followed, or rathet 
superseded, by the much sounder Species, Genera, et Urdines Al- 
g seu Descriptiones succincte speciorum, generum, et oI”
