no central leader (compare Figs. 42G and 427, Vol. 1): 

 Ivs. ovate-obovate or short-ovate, abruptly short -pointed, 

 stiff and parchment-like and more or less glossy above, 

 light or gray-green: fls. in small clusters from lateral 

 buda mostly in advance of the Ivs., the scales of the 

 fl.-buds small: fr. roundish or depressed-globular, red, 

 soft-fleshed, acid: stone globular. Native to Asia Mi- 

 nor and perhaps to southeastern Europe.— -P. Cerasus 

 is the common Pie Cherry of old yards. It escapes into 

 fence-rows and other waste places, forming dense 

 thickets, as the Plum does. It sprouts from the root. 

 The various Morellos belong here; also the Montmo^ 

 rency, Louis Phillippe, and others. There are at least 

 two well-marked groups of these pomological Cherries— 

 those with uncolored juice (Amarelles. thePnotus acida 

 of some), and those with colored iuin- i.Moirllos or 

 Griottes). To the former group bel"iii; iln- Mi.nt iiM.n-ncy, 

 Early Richmond, and several rm-lv vinini,.. The 

 Primus acida of Karl Koch {Cerax„s ,ir,,l.i. Imnmrt.) 

 is a bush-like plant with slender pendulous Ijranches 

 and smaller Ivs., the petioles usually gland-bearing (less 

 so in P. Cerasus ) , the fruit dark red and sour, the stone 

 ovoid; of this plant P. semptrnorens (No. 23) is a form.
