Smaller-growing evergreen or semi-evergreen clone. (var. chilensis. 'Sempervirens')
Probably raised in Chile as a somatic mutant of the Lombardy Poplar; growth is often at first more rapid than that of var. italica; it is a male clone susceptible to rust fungus, now rarely planted and usually grafted onto P. simonii stock to prevent suckering.
Introduced to Australia from South Africa before 1955. A large suite of material was raised at the Botany Department of Australian National University in Canberra from crosses between this clone and P. deltoides commencing in 1965 and a few of these have found use in public plantings e.g. at Australian National University (Burgmann College).. The clone 65/1 is one such clone which is semi-evergreen and relatively rust-resistant. 65/31 is deciduous and is now used in silviculture. Others include 65/5, 65/88 and 65/99.
