very great, occupying nearly seventy pages. We lament to learn that 
severe domestie calamity has for a time checked the zealous career of 
this talented author. 
MrEms: Illustrations of South American Plants. 
'The 4th Part of this work has just appeared, with treatises on the 
genera Nierembergia, including nineteen species; Vestia (one species) ; 
Nicobaria, Petunia (eight species), among Solanee. These are followed 
by an account of a remarkable new genus, Sclerophylax, the type in- 
deed of a new Order, from inter-tropical South America, La Plata ; 
and, lastly, by an account of Cyphocarpus, a new Chilian genus, allied 
to Campanulacea, Lobeliacee, Goodenoviacee, Cyphiacee, and Stylidiacee, 
yet differing from all. The plates and copious dissections are no way 
inferior to the previous ones, and consist of Tab. 23, Petunia parviflora; 
Tab. 24, Petunia ovalifolia, and Petunia elegans ; Tab. 25, Sclerophy- 
lax spinescens; Tab. 26, Sclerophylax Arnottii and Gilliesii ; Tab. 27, 
Cyphocarpus rigescens: and 28 (of which the descriptions will appear 
in a following No.)—Salpichroma hirsuta, S. tristis, and S. diffusa 
GARDINER: Twenty Lessons on British Mosses; second series, illus- 
trated with twenty-five specimens. Longmans, 1849. 
We have noticed, with the praise it merits, the first series of this 
interesting and useful publication, so well calculated to encourage a 
taste for the study of the Mosses, and so well calculated also to give 
information on the subject of which it treats. We have, in the Intro- 
duction, the method described for collecting and preserving these beau- 
tiful objects, and then, in the first Lesson, an account of the Classifica- 
tion of Mosses, adopting that of the British Flora, as the most simple, 
with brief characters of the genera ; and the two great divisions of the 
family Acrocarpi (fruit terminal), and Pleurocarpi (fruit lateral), are 
speakingly illustrated by a specimen at the head of each respective 
section; while the remaining “lessons” are each devoted to a genus 
and a full description of one or more species illustrated by specimens. 
We trust this little work will meet with the success it well deserves.
