NEW OR NOTEWORTHY SPECIES. 299 
and inversely ascending, i. e. the basal end uppermost, and 
that distinctly favose-reticulate, the whole surface hispidu- 
lous, the back with an ovate depression surrounded by a 
slightly raised and somewhat denticulate margin and traversed 
in the middle by a more or less prominent ridge, the 
cartilaginous yellowish caruncle double, or at least deeply 
2-lobed. 
Western slope of the Washoe Mountains, Nevada, July 22, 
1888, Mr. C. F. Sonne. 
This is about the most interesting of Mr. Sonne’s many 
new discoveries in this alliance of plants; and, while the 
species confirms the genus Sonnea, and most resembles S. 
hispida, its nutlets recall those of Omphalodes in their exca- 
vated, or at least, much depressed dorsal part. The singular 
double caruncle will be taken as indicating that two nutlets 
have become one, and this organ, which is as much of the 
nature of a stipe as of anything, alone remains disjoined. 
viscid throughout: cauline leaves oval, 
inch long, on slender petioles of nearly equal length; the 
lower with some lyrate lobes at or below the base of the main 
blade: racemes solitary or in pairs, elongated, dense : calyx- 
lobes spatulate, entire, f inch long, exceeding the 4-seeded 
capsules: corolla bright blue, narrowly funnelform, $ inch 
long, the limb one half as broad: seeds oval, black, deeply 
favose-pitted. 
Plentiful at the Petrified Forest, Sonoma County, California; 
collected by the author late in August, 1888. It is another of 
those species which eliminate the boundaries of subgenera or 
sections; for it combines the capsule and seed of Euphacelia 
with the narrow elongated corolla of Microgenetes. 
The delightful fragrance of the herbage, inhering in even 
the well dried specimens, is almost new in the genus; most 
of the species yielding a disagreeable odor.
