M. EUBELLUS Gray, needs careful study in the field. In 

 some forms at least, and especially through montioides, it 

 approaches M. hicolor so ck:»sely in the structure of the ca]3"x, 

 as well as in the corolla, that if the separated tips of the 

 placent'cX3 are found inconstant, it will be difficult to keep 

 them apart. 



M. Parishii Greene, judging by the roots, is certainly 

 perennial, though quite possibly it blooms also as an annual. 

 The lobes of the corolla are cmarginate; the seeds reticu- 

 late on the surface, but the coat is certainly not loose.

The characters of this plant are obscured by drying under 

 pressure, on which account it has long been misunderstood. 

 The calyx is ovate-ventricose, much like that of 31. Ratiani, 

 ratlier deeply 5-sulcate, often weakly angled and nerved, 

 and theplacenta3 are separated three-fourths of their length. 

 Tlie plant shares its "sickening solanaceous odor" with 

 3iimulus inctiis and at least some forms of ilf. Bolanderi.

It is to be hoped that any future revision of this section 

 of 31imulus will include all the known forms, especially the 

 South American and Mexican, most of which are very 

 doubtfully distinct from ours. 



M. BicoLOR Hartw., although its placenta in all forms 

 known to me are firmly united to the top, is anomalous in 

 this division, being most closely related to rubellus, as 

 noted above.
