This paper embraces observations upon the various forms, both 

 wild and in cultivation, their synonymy, &c, with remarks on the 

 variability of the species.

 tabilis. — Heft. xiv. Bonn. 



This part contains detailed descriptions of about twenty natural 

 orders or sub-orders, in Latin and German, with figures and elabo- 

 rate dissections. The illustrations of the orders are not issued in their 

 natural sequence, but indiscriminately, as the author finds material. 



Einige merkwiirdige Formen von Ovula bei Monocotylen . — 



Flora, 1860, pp. 529-32. These remarks apply to the ovules of 

 Astelia Banhsii and Conostylis dealbata. 



In the former the anatropous ovules are provided with a long, 

 curved funicle, which eventually becomes bent at an angle over the 

 micropyle ; opposite to this point a plait or fold is developed, which 

 covers a considerable portion of the outer side of the ovule. In Co- 

 nostylis, Sehnitzlein finds the ovules to be orthotropous, with two 

 well-marked integuments. The cells of the outer coat are transverse 

 to the axis of the ovule, and give it a wrinkled aspect. It finally 

 assumes a remarkable appearance, from resting upon a bulbous 

 raised base, as though two ovules were superimposed with a constric- 

 tion between them. The thickened funicle or support is shorter than 

 the ovule.

In plants out of doors an alteration in the position of the leaf was 

 observed in species of Edwardsia, Sophora, Colutea, Caragana, Lu- 

 pinus, Vicia, Oxalis, &c. Several others under glass, chiefly Legu- 

 minosse and Oxalideae, distinctly manifested the phenomena of 

 " sleep." None of the expanded flowers which were observed (JVt'co- 

 tiana, Mirabilis, (Enothera), showed any alteration with the dimi- 

 nished light.
