tial favor. Such collections, if made with a very slight degree of care, 
so as to ensure a variety of species, and especially from your southern 
‘states would be very acceptable. The best time for collecting is at

It will give the writer of this notice great pleasure to forward to Dr. 
Harvey such collections of our Alge as may be entrusted to his charge, 
and to return sets authentically named to those who are desirous of 
making these exquisitely beautiful pane the subject of scientific study.

and Uses of Plants, illustrated upon the Natural System, (London, 
1846, pp. 908, Svo., with upwards of 500 illustrations,) is, as it were, 
an aalarge™ and greatly modified edition of this author’s former Intro-

11. Martius, Genera et Species Palmarum.—The 8th fasciculus of 
this splendid work, published last September, has come to hand. It 
comprises, Ist, the concluding sheets of the systematic portion; 2d, a 
full account of Fossil Palms, by Prof. Unger, of Gratz, who, by th 
way, has recently published, at Leipsic, a Synopsis Plantarum Fos- 
silium, in a single 8yo. volume, which will be very useful to geologists; 
and 3d, a dissertation on the growth and morphological structure: of 
Palms, by Prof. Von Martius himself. His conclusions respecting the 
structure and growth of the palm-stem, differ materially from those of 
Desfontaines, De Candolle, as well as from the view of Gaudichaud, 
but are nearly in accordance with the views recently maintained by 
Misbel, in his memoir on the date-palm, &c. A. Gr.
