22 ERYTHEA. 



MiMULUS PRiMULOiDES, Benth. Scroph. Ind. 29 (1835). 

 Mr. Bentham's characterization of this plant is as follows: 

 "Glabrous, stoloniferous; flowering branches short; leaves 

 subsessile, obovate, obscurely dentate or very entire: pedicel 

 elongated, solitary, terminal: calyx tubular, short-toothed." 

 It is an insufficient account to have given of one of the most 

 beautiful species of the genus. The corolla is about f of an 

 inch long, nearly as broad; the limb almost perfectly regular, 

 each one of the 5 lobes being notched deeply, almost to the 

 obcordate, so that it is in actual appearance 10-lobed, With 

 this large-flowered, large-leaved glabrous plant, the following 

 has long been confused. 



Mimulus pilosellus. Very small, depressed, compact 

 and almost moss-like: leaves ^ to ^ inch long, round-obovate? 

 obtuse, more or less cuneate at base, sessile, glabrous beneath' 

 hoary above with white jointed hairs nearly as long as the 

 diameter of the leaf; stems also similarly pilose but these 

 hairs not as long: corolla only ^ inch broad. 



Habitat of the preceding, and even more common; often 

 hybridizing with it; so that forms variously intermediate 

 between the two are very common. The species are, never- 

 theless, doubtless two, the intermediates evidently natural 

 hybrids, and not merely intergradational forms. 



Attention having been called in the last volume of 

 Erythea, page 179, to the beautiful mimuloid shrub from 

 Southern California, published in Gaixlen and Forest for 

 last April, it may here be noted, that the plant is clearly no 

 Mimiilus, but a perfect Diplacus, to be called 



Diplacus Clevelaiidi. Mimulus Clevelandi, Brandg., in 

 Gard. & Forest, viii, 134, f. 20.
