Greene — Some TfW American Red Cherries. 59 



Cerasus padifolia sp. nov. 



Shrul) irlahroiis in every luirt except the cadiicous stipule?, tliese in their 

 time yianihilar eiliolate ; leaves of flowering hranehes (juite copious, 1 to 

 lij inches long, obovate-oblong, obtuse, tapering to the short-petiole, mi- 

 nutely crenulate, the midvein beneath conspicuous, the pinnate veins less 

 so; corvnihs fastigiate, about 7 to n-llowered, on peduncles of I inch or 

 less, the pedicels rather longer ; calyx-tube turbinate, one-third longer than 

 the deflexed segments, these oblong-ovate, very obtuse or even truncate ; 

 petals not large, round-obovate al)ove the tapering base. 



Foothills at Carson City, Nevada, June 2, 1897, Marcus E. Jones. Type 

 in U. S. Herb. Though in flower only, the specimens, by their ample 

 fastigiate inflorescence and long slender calyx-tube with short segments, 

 refuse to be consociated with those of any other western cherry. 



Cerasus obliqua sp. nov. 



Slender red and shining leafy branches nearly glabrous, clothed with 

 only sparse appressed hairs; leaves of fruiting branches mostly obovate- 

 oblong and obtuse, rarely emarginate, crenulate, 2 or 22 inches long, glab- 

 rous above, sparsely short-hairy beneath both along the veins and else- 

 where, those of sterile branches lanceolate, acutish, not larger than the 

 others; flowers not seen; drupe evidently subglobose; stone obliquely 

 ovoid, obtuse at both ends, prominently but obtusely rugose, inequilateral 

 at base by the strong development of thick margin below the middle. 



Known to me in but a single sheet of specimens in U. S. Herb, obtained at 

 Oroville, Calif, Oct. 2, bS96, by H. E. Brown. Strongly marked by the 

 characters of its pubescence and oblique thick-margined stones; and these 

 specimens are the only ones known or heard of by me of any cherry from 

 the plains or foot-hills of the interior valley of California. 



Cerasus parvifolia sp. nov. 



Slender shrub, either fastigiately or more widely l>ranching; branches 

 led-ljrown and polished, puberulent at first, when mature glabrous, copi- 

 ously leafy; leaves small, short-i)etioled, those of fructiferous branches 

 cuneate-obovate to oblong-cuneiform, I to 1 inch long, thinnish, obtuse but 

 never emarginate, finely crenulate, those of sterile shoots larger, I to 1} 

 inches long, broadly elliptic, acute, all faintly puberulent when young, 

 still more obscurely so in age, notably white-vennlose beneath, suprabasal 

 glands mostly wanting altogether, occasionally present in reduced form ; 

 flowers unknown ; drupe ovoid ; stone about 3 or 3^ lines long, narrowly 

 ovoid, very acute at apex, equilateral, one side with a broad flat marginal 

 development, the otiier showing a mere impressed line, surface with several 

 traces of longitudinal ridges radiating about the base but soon vanishing, 

 otherwise smooth, or wholly smooth, and showing no traces of rugosity.
