 ON SOME CALIFOENIAN MIMULI. 



By Edward L. Gbeene. 



In publishiug, a year since, in the London Journal of Bot- 

 any^the Mimuhis implexus of the Sierra Nevada, I made an 

 unfortunate mistake in assigning to that species an " exceed- 

 ingly thin-membranaceous " leaf-texture. The plant which I 

 had in mind, as to the matter of texture of herbage, is one 

 which, although growing in the same district^ and often along 

 with T. implexus, I last summer discovered to be a totally 

 different thing; and I here name it 



Minmlus corallinus. Perennial by strings of fragile 

 moniliform white rootstocks, the joints of these short-clavi- 

 form; proper roots slender-fibrous: stems erect, slender, 4 to 

 12 inches high, simple or with branches from the base, leafy 

 up to the short raceme, bright green, appearing glabrous, 

 but more or less hispidulous-puberulent under a lens : leaves 

 very thin membranaceous, neither viscid nor slimy, ovate or 

 round-ovate, short-petioled or subsessile, saliently toothed, 

 the floral much reduced, not connate : flowers few, short-pedi- 

 celled, about 1 inch long; the strongly bilabiate corolla about 

 f inch bi'oad. 



Inhabiting dry alluvial banks, either in the open, or in 

 shade of bushes; the rootstocks sometimes with shorter and 

 thicker joints, thus becoming actual jointed tubers, as in M. 

 moniliformis. Plentiful along the western base of the 

 Washoe Mountains beyond Truckee, but also near Summit 

 Station, from which latter district it has been distributed by 

 me under the name of 31. Tilingi. 



In M. implexus, Greene, Journ. Bot. xxxiii. 8, the leaves 

 are not only of unusual thickness and fleshiness of texture; 

 they are entirely covered by translucent dewy-looking parti- 

 cles, so that upon being ^handled, especially with moist 

 hands, these particles burst, and cover the leaf surface at 

 once with a thick albuminous slime. The character of the 

 underground part of this species is, as I have more than once 

 before described it, altogether unique.
