632 -FLORA OF SOUTH AMERICA. 
revise the whole order for the Prodromus. In the meantime, 
Dr. C. A. Meyer, in the Bulletin of the Academy of St. Pe- 
tersburgh, has proposed a generic distribution which appears 
very satisfactory with relation to the European, Asiatic, and 
a portion of the American species, but which may require 
some modification as to the latter, when more of them shall 
have been examined. Nordmannia, for instance, (if I am not 
right in the plant I consider to be N. tinifolia), well distin- 
guished by the stamens adnate to the lobes of the corolla, is, 
by the more or less complete abortion of the organs of one sex, 
usually dicecious, not truly hermaphrodite, and has small scales 
round the base of the ovary. It is a natural genus, containing at 
least half-a-dozen American species, including Daphne salici- 
folia, H.B.K., D. cestrifolia, H.B.K., D. Bonplandiana, Kunth, 
(vix Cham. Schlecht)* and some unpublished species. The only 
species of the order contained amongst Schomburgk’s plants, 
belong to genera perfectly distinct from any I am acquainted - 
with. |

* D. Bonplandiana, Cham. Schlecht. (which I, have not seen), with a 
glandular ring round the ovary, forms Meyer's genus Hargasseria, Galeotti’s 
specimens from the same locality (n. 523) have on the contrary the cha- 
racter described by Kunth, and appear to me without doubt to be: con 
genera with Nordmannia tinifolia.
