gibbous throat and rotate corolla-lobes. It is clearly an offshoot 
of the section Eunanus, deviating in the direction of an unusual 
corolla. 
Pseudoenoe.—The single species in the section Pseudoenoe is 
8 curious desert plant, combining characters of the sections 
Diplacus, (Епов, and Mimulastrum. Although M. pictus was 
placed in the section Mimulastrum by Dr. Gray, the only char- 
acter to keep it there is its peculiar corolla, which is similar to 
that of M. mohavensis. The latter species has the calyx, style, 
and capsule of members of the section Eunanus, whereas M. pictus 
has a calyx more like that of Diplacus, and the style, stigma, and . 
capsule of M. Kelloggii of the section (Епое. The capsules of 
M. Kellogg and of M. pictus, upon being boiled, open in the 
same manner as that of Diplacus; moreover, the rupturing of the 
calyx by the opening capsule and the woody base of the style 
which persists in M. pictus increases the resemblance to Diplacus. 
Without doubt the very different calyx and capsule prevent 
leaving M. pictus in the section Mimulastrum and equally, the 
peculiar corolla, unlike that of any other Mimulus except M. 
mohavensis, prevents putting it in the section ( пов, to which 
most of its characters indicate relationship. 
(Ұпое.--Тһе section (Епое is closely related to Eunanus, dif- 
fering in its peculiar calyx and capsule as well as in its long ex- 
serted corolla-tube. This last character, however, does not al- 
ways hold true as through M. latifolius and M. Congdonii there 
is а gradual shortening of the corolla-tube until it approaches 
that of typical Hunanus. The capsule in all of the forms studied 
is very distinct, being cartilaginous, more or less woody and gib- 
bous at the base and indehiscent or tardily dehiscent along the 
inner suture, often breaking away near the base. The calyx 
with its very unequal herbaceous teeth, differs from Eunanus 
in that it closely invests the capsule and is gibbous and scarious 
at the base. (noe varies from true Diplacus inasmuch as the 
calyx is rarely ruptured by the capsule and, with the exception 
of M. Kelloggii, the type of dehiscence is unlike that of the other 
sections. А
