For horticultural purposes, these five main groups may 

 be illustrated as follows: 



1. Plums and apricots I. Prunophora 



2. Common or fascicled cherries ,11, Cerasus 



3. Uacemose cherries III. Padus. 



4. Dwarf almonds IV. Cham.«;amygdalus 



5. Almonds and peaches V. Amyodalus 



Fruit sulcate, glabrous and usually glaucous (except 

 in the apricots), the stone compressed and usually 

 longer than broad and smooth or nearly so: fls. solitary 

 or in umbel-like cymes, mostly appearing before the lvs. 

 or with them: lvs. mostly convolute in vernation, gen- 

 erally ovate or lance-ovate. 



A. Apricots,— tte fls, solitary or in 2's, before the lvs. 

 and the fr. velvety {at least until ripe): stone 

 usually sulcate on the margin: peduncle separat- 

 ing from the mature fruit. 

 1. Armenlaoa, Linn. (Armenlaca vulg&ris, Lara.). 

 Common Apricot. Figs. 113-117. Small round-topped 

 tree with reddish bark much like that of the peach tree: 

 lvs. ovate to round-ovate, sometimes slightly cordate at 

 the base, abruptly short - pointed, glabrous (at least 



overlaid more ur less with red, the stone lUit and smooth, 

 ridged or sulcate on one edge. Said by Focke to be 

 native of Turkestan and Mongolia; by some regarded 

 as Chinese. It early reached Europe, where it was once 

 supposed to be native of Armenia, whence the name 

 Armeniaca. The Russian Apricot is a hardy race of 

 this species. See Apricot and Figs. 113-117 in Vol. I. 

 The smooth-fruited Apricot. P. Jirigantiaca, Vill., is 

 regarded by Dippel as a form of this species, var. 

 Brigantlaca, Dipp. Shrub or small tree, with smaller 

 lvs. and smaller smooth subacid fruit. Probably a cul- 

 tural variety. Run wild in southern France and Pied-
