ACTINOSTROBUS PYRAMIDALIS (Miguel). 



PI. Preiss. I. p. 644 (1847). 



Baker and Smith, Pines of Australia, p. 291 (1910). 



A shrub of pyramidal habit with rigid fastigiate branches and 

 branchlets. Leaves in whorls of three, decurrent, -J- inch long, 

 with rigid, acute or acuminate, free and spreading tips. 



Male catkins & inch long, the stamens in whorls of three, in 

 six vertical rows. Cones inch in diameter on short stalks, sur- 

 rounded at the base by closely appressed imbricated sterile scales ; 

 globose or ovoid, consisting of six inner valvate scales, each bear- 

 ing one or two three-winged seeds. 



The genus Actinostrobm is closely allied to Callitris, the imbri- 

 cate sterile scales at the base of the cone forming one of the best 

 distinguishing characters. It is only found in a wild state in 

 Western Australia, the recorded localities being King George's 

 Sound, Swan River and Murchison River. It has not yet been 

 grown in the open air in England. 



The illustration represents a specimen obtained from Antibes, 

 France, by Dr. A. Henry.
