 Rapid growers ; very ornamental ; greenhouse in the

 without irrigation.

CALLlTEIS (from the Greek for heantiful). Conif- 

 era, tribe Ctipresshiea. About 15 trees or shrubs, 

 growing in Africa and the Australian region, allied to 



CALLUNA 



The small cones have 4-6 separating woody 

 scales : lvs. small and scale-like, persistent. Of very 

 attractive habit. The only species in the Amer. trade is 

 robiista, R. Br. Cypress Pine. Somewhat resembles 

 our native red cedar, but is conical in form and very 

 dense. It is a fine tree for tall hedges and windbreaks. 

 Yoiiu^ trees planted out in S. Fla. make fine specimens, 

 lirauchini^ from the ground. In five years the plants 

 reach 10-12 ft. high. Little known in this country.
