HARDY CONIFEROUS TREES 105 



neat, conical outline, well branched, and the 

 foliage like our common spruce, but much lighter 

 in colour. Cones are produced freely, these being 

 dull brown when ripe, i| inches long and cylin- 

 drical in shape. There is a variety P. alba 

 ccendea, 



P. Alcockiana, Carriere. (Synonyms : Abies 

 Alcockiana, Veitch ; Picea bicolor, Mayr ; A. aci- 

 cularis, of gardens.) Mountains of Japan. 1861. 

 — The appearance of young trees, sent from a 

 reliable source under the present name, is certainly 

 different from that of P. hondoensis, the leaves 

 being more needle -like, four angled, far more 

 prickly, and the colour not so decided a silvery 

 tint. The leaves have usually two lines of stomata 

 on the uppermost faces, and four to seven lines 

 beneath. It grows quite freely, and has formed 

 a dense specimen of regular outline, except for 

 the upper branches, which project here and there 

 beyond those further down, and the plurality of 

 leading shoots. The young shoots of the present 

 tree are flattish on one side, while those of P. 

 hondoensis are rounded or cylindrical. Mayr's 

 name of P. bicolor is adopted by some authorities 

 for this species. 



P. Breweriana, S. Watson, Brewer's Weep- 

 ing Spruce. North Carolina, Siskiyou Mountains. 

 1897. — This is one of the most locally distributed 

 of all the spruces. It differs from every other in 

 the long pendulous branchlets, which hang thin 

 and flexible from the main branch to a great 

 length. The bark becomes of a warm reddish 

 tinge with the advance of years ; and the leaves, 

 which resemble those of the Norway spruce, but
