able structure of the ovary in the genuine genera of that order. 
The various groups often separated from Symplocos are here 
very properly referred back to it as sections, and the two 
principal genera, Symplocos with fifty-six species, and Styrar 
with forty-five, from being amongst the most confused are 
now amongst the best defined, although our collections already 
contain a considerable number of additional species. In the 
ordinal character there is a slight omission, that of any allu- : 
sion to some of the anomalies of Pamphilia, especially the 
reduction of the number of stamina to five. 
Oleacee and Jasminacee form together a small group (for- 
merly and perhaps more conveniently considered as one order) 
distinguished amongst Corolliflore by the stamens constantly 
reduced to two, regularly inserted with relation to the bicar- 
pellary ovary (alternating with the carpels?) and not in rela- 
tion to the divisions of the corolla, unless where, as in O/eacee, 
this is tetramerous; and also regular in its relation to the 
ovary, whereas in all the succeeding orders, when any re- 
duction takes place, the remaining stamens are irregularly 
placed with reference to the ovary, which is neither opposed 
to nor alternating with them. These Orders were prepared 
by the elder De Candolle in 1840 (or early in 1841 ?) from the 
materials he possessed at the time, and a few notes with two 
new genera, Nathusia and Kellaaa, have now been added by 
his son. "There does not, however, appear to be any quota- 
tion of Cuming's or other more recent collections, and the set 
of East Indian Jasmineæ, sent to the author by Dr. Wallich, 
was very far from complete. The enumeration is, therefore, 
less comprehensive, and the species not so well extricated a$ 
might now be done; still the general arrangement is good. 
The remaining orders in the two volumes, with those 
which will occupy the two or three succeeding ones, have all 
epipetalous stamens, always alternating with the lobes of the 
corolla, whether equal to them in number, or more or less 
reduced. Of these orders, two large ones closely allied to 
each other and formerly considered as one, the Apocynaceé 
and Aselepiadacee, close the eighth volume. Both are known
