34 EVERGREENS OF COLORADO 



This tree is planted to some extent for ornamental purposes and 

 when well grown is worthy a place in any grounds. It may be expected 

 to thrive better in the southern portions of the state and at lower altitudes 

 than the preceding species. 



5. GENUS Juniperus. THE JUNIPERS, RED CEDARS, SAVINS. 



The members of this genus are readily distinguished from the other 



members of the pine 

 family in Colorado, 

 first, by the needles 

 which are either scale- 

 shaped or awl-shaped 

 and are usually borne 

 in pairs on opposite 

 sides of the twigs or in 

 whorls of three; sec- 

 ond, by the fruit, 

 which instead of ripen- 

 ing into a dry cone 

 composed of woody or 

 papery scales, forms a 

 berry-like fruit with 

 but few seeds. Also the 

 staminate and pistillate 

 flowers occur on sepa- 

 rate individual trees 

 of the same species, 

 instead of being on the 

 same individual tree, 

 as in the other mem- 

 bers of the pine fam- 

 ily. The staminate 

 flowers are produced 

 in tiny cone-like clus- 

 ters, composed of ten 

 or a dozen scales, each 

 bearing two to six 

 pollen sacs. These may 

 frequently be found 

 fully developed in 

 autumn, ready to dis- 

 charge the pollen in 

 early spring. The pis- 

 tillate cones are like-

 preceding summer and autumn and occur at the tips of very short lateral 

 branchlets. Each consists of two to six scales, standing opposite in 

 pairs and when in bloom, the tips of the two ovules may be distinguished
