Macbride — Certain North American Umbelliferae 35 
come convinced that the plants considered by Coulter & Rose, 
l. c., as constituting a distinct genus are much better, indeed more 
naturally treated as species of Lomatium. Prof. M. E. Jones, 
Contrib. W. Bot. xii. 32, 35 (1908) has expressed the same opinion 
and has shown that Cynomarathrum cannot be separated satis- 
factorily from Lomatium by virtue of the habit or the winging of 
the fruits as attempted by Coulter & Rose, l. c. 245. Nor does the 
fact that the calyx-teeth are evident furnish a means of distinction 
as they are quite obvious in L. macrocarpum. The one character 
at all times constant is the presence in the species that have been 
referred to Cynomarathrum of a more or less evident stylopodium. 
This is flat, however, and consequently scarcely obvious and 
surely not to be regarded as alone possessing value for defining a 
genus in a group of plants alike in aspect and in other characters 
of moment. Finally it may be mentioned that the original of C. 
Nuittallii collected by Nuttall bears on the sheet in Dr. Gray’s 
hand the statement “‘ Will do for a Peucedanum,”’ that is, a Loma- 
tium as now understood. Watson, Aven Nelson, Jones, Drude, 
and even Coulter & Rose have at one time or another regarded 
without question species of this alliance as good Lomatiums. This 
disposition of these plants will necessitate a number of new com- 
binations of which the following may be made now.
