1. Juniperus communis, L. Juniper. 



Leaves in ternate whorls, spreading nearly at right angles to the branchlets, linear- 

 lanceolate, acute and tipped with sharp slender points, articulate and truncate at the 

 base, thickened, rounded, obscurely ridged, dark green and lustrous on the lower 

 surface, snowy white and covered with stomata on the upper surface, \'-^' long, about 

 3*3 ' wide, turning during winter a deep rich bronze color on the lower surface, per- 

 sistent for many years. Flowers : staminate composed of 5 or 6 "whorls each of 3 

 stamens, with broadly ovate acute and short-pointed connectives, bearing at the very 

 base 3 or 4 globose anther-cells; pistillate surrounded by 5 or 6 whorls of ternate 

 leaf-like scales, composed of 3 slightly spreading ovules abruptly enlarged and ope.n 

 at the apex, with 3 minute obtuse fleshy scales below and alternate with them. 

 Fruit maturing in the third season, subglobose or oblong, tipped with the remnants 

 of the enlarged points of the ovules, about \' in diameter, with soft mealy resinous 

 sweet flesh and 1-3 seeds; often persistent on the branches one or two years after 

 ripening; seeds ovate, afcute, irregularly angled or flattened, deeply penetrated by 

 numerous prominent thin-walled resin-glands, about \' long, the outer coat thick and 

 bony, the inner membranaceous. 



In America only occasionally tree-like and 20-30 tall, with a short eccentric ir- 

 regularly lobed trunk rarely a foot in diameter, erect branches forming an irregular
