NEW SPECIES, MAINLY CALIFORNIAN. 97 
and by Howell The species a most beautiful one, lacking 
the villous pubescence of E. Bigelovii and otherwise dif- 
ferent. 
EvNANUS SUBSECUNDUS.— Mimulus subsecundus, Gray, l. c. 
Apparently eommon near Antioch, where it was again col- 
lected in 1886 by Mrs. Curran. 
MIMULUS ARVENSIS. Annual, erect, slender and simple, 
1—24 feet high, stem more or less quadrangular, sparingly 
leafy, loosely racemose from the middle: lower leaves on 
long petioles, roundish, coarsely toothed and hastate, or the 
petioles bearing many accessory leaflets, the leaf thus becom- 
ing lyrate ; floral leaves soft-white-villous beneath, all other 
parts of the plant glabrous: pedicels an inch or two long, 
slender and ascending: calyx campanulate, 3—4 lines long, 
purple-dotted, the orifice scarcely lobed, in fruit twice as 
large, short-cylindrical, almost truncate at base as well as 
orifice : capsule nearly orbicular, compressed, 2—3 lines long : 
seeds brownish, nearly smooth. 
This plant was first known to me in a specimen or two 
brought from Lake County in 1884, by Mrs. Curran. I have 
mentioned it on page 112 of the first volume of California 
Academy Bulletins, under M. microphyllus. In the spring of 
1886 I was surprised to find it common in wheat fields among 
the growing grain, in both San Mateo and Marin counties, 
not far from San Francisco. It is strictly annual and very 
unlike the common M. guttatus to which, under the name of . 
M. luteus, a large number of our species and subspecies were 
until recently referred. In the districts named the large per- 
ennial will be met with in the same field with the annual, if a 
streamlet or springy place exist; and this not rarely 5 feet 
high, bearing a truly magnificent panicle of racemes, some- 
times the whole cluster nearly 2 feet long, and half as broad ; 
and the annual here defined will be in seed and dying while 
its neighbor of the streamlets is not yet in full flower toward 
the end of April. I should have been happily instructed if
