Cedrus 469 



or those grown in England. Though at the time I did not think they were 

 mature, yet the seeds contained in them have germinated and produced young 

 plants, which in July were just putting forth their second whorl of leaves, but by the 

 following May had increased very little in size, being much smaller than those of 

 the same age from Swiss and English seed. 



Plants were raised at Kew from seed received in 1881; and two, now growing 

 in the cedar collection at Kew, have attained only 6 feet in height, and are remarkable 

 for their singularly short leaves and stunted bushy appearance. A number of them 

 were killed by the winter, having been planted out when too young, which seems to 

 show that this variety is more tender than the Lebanon tree. (H. J. E.)

Young trees stiffer in habit than the Lebanon cedar, and with an erect leader. 

 Branchlets not pendulous, covered with short dense pubescence. Leaves up to an 

 inch (occasionally in cultivated specimens i|- inch) long, usually as thick as or thicker 

 than broad. Cones shorter and more cylindrical than in C. Libani; scales i^ inches 

 in width, claw inflected. 



Varieties 



Yax. glauca. In the cedar forests of Algeria a certain proportion of the trees 

 have glaucous foliage, the leaves being marked above with conspicuous white 

 stomatic bands ; but there is no other difference, and no foundation exists for the 

 opinion, first mooted by Jamin,^ that the glaucous variety constitutes a distinct 

 species.* The glaucous tint is an essentially unstable character,* trees occurring in 

 the wild state in which glaucous leaves appear only on some of the branches. This 

 variety often arises in cultivation. 



Beissner^ mentions several varieties, which have been obtained in cultivation, 

 d& pyramidalis, columnaris, andi fastigiata,^ characterised by peculiarities of habit ; and 

 a variegated form in which the foliage of the young shoots is yellowish,^ but so far 



Manetti gives the name only without any description, in the second supplement to his catalogue (1845), and not in the 

 first supplement (1844) as usually stated. Endlicher first described the Atlas cedar from plants 6 inches high, sent in 1 847 

 by Manetti from the Royal Gardens at Monza (Modicia) near Milan.

 seedling in Lalande's nursery at Nantes. Cf. Card. Chron. vii. 197 (1890). 



' Var. aurea, young foliage of a rich golden colour, which changes to the normal green of the species in the second year. 

 This variety is mentioned by Kent, loc. cit.
