18 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
The four following are pre-Linnaean genera not recognized by Lin- 
naeus, but afterwards restored as indicated: 
Torilis Adanson, Fam. 2: 99. 1763. No species cited. 
4 Foeniculum Adanson, Fam. 2: 101. 1763. =Anethum foeniculum L, 
Levisticum Koch, Noy. Act. Caes. Leop. Acad. 12: 101. 1824. =Ligusticum 
levisticum L. 
Petroselinum Hoff. Gen. Umb, 78. 1814.=Apium petroselinum L. 
In only twelve of the post-Linnaean genera, including the three 
genera here published for the first time, were there more than one 
species included in the original description. In some of these genera 
the type is indicated, while in the other cases we have cited the first 
species. These genera, with the number of original species, and with 
the type species or first species cited, are given in the following table:

Torilis and Foeniculum, pre-Linnaean genera, were restored by Adanson in 1863. 
Conioselinum, described by Hoffman in 1814, was redescribed in 1816, with C. 
tartaricum as the type. 
Bowlesia was described by Ruiz and Payon in 1794, but with an unnamed plate of 
B. palmata, which was named a few years afterwards. 
We have given the general geographical range, and such important 
specimens as have been studied in preparing this monograph are cited. 
It should be remembered, however, that the range given is often the 
reported range, while the range as we know it is shown by the speci- 
mens cited. It will be noticed that a great many specimens cited in 
the Revision are not included among those cited in the Monograph, 
so that the latter work represents a great extension of the horizon so 
far as it can be furnished by material. 
It has been thought wise to assist in the recognition of genera by 
including in the text illustrations of characteristic fruits, showing both 
= surface and cross section. Every genus containing native species is 
illustrated either by a plate or by at least two text cuts. A few of the 
figures have been published before, but for the most part the draw- 
ings have been prepared by Miss Anna Synder, under the direction of 
J. N. Rose. The drawings forthe plates were made by Mr. Frederick 
A. Walpole. 
We have also attempted to separate with great distinctness the 
native genera and species from the introduced ones. Accordingly, 
the latter are grouped together at the end of the Monograph, but are 
included in the general keys.
