Cupressus 1185 



Seeds were introduced into Germany by Purpus, 1 who says it is the hardiest of 

 all the true cypresses, and that young seedlings grow extraordinarily fast, but are 

 somewhat difficult to transplant. Beissner, 2 however, states that in many parts of 

 Germany it is tender and has suffered much from frost. 



At Angers there is a tree of this species with remarkably glaucous silvery 

 foliage, which bore fruit in 1907. Elwes found this also in E. Rovelli's nursery at 

 Pallanza. He also saw a fine specimen under the name C. guadalupensis in the 

 Botanic Garden at Montpellier. It was about 30 ft. high, with handsome glaucous 

 foliage, but bore no fruit. (A. H.)

A tree, attaining in Japan 120 ft. in height and 12 ft. in girth, larger trees 

 of very rare occurrence being reported by Mayr. Bark reddish brown, scaling off in 

 long thin strips. Branches and branchlet systems similar to those of C. Lawsoniana. 

 Ultimate branchlets flattened, compressed, T X F in. wide. Leaves appressed ; lateral 

 pair conduplicate, T x ^ in. long, obtuse at the apex, which often bears a minute mucro ; 

 facial pair, much smaller, ^ in. long, flattened, rhomboid, often keeled, non-glandular, 

 with a triangular scarcely acute apex. The foliage is dark green on the upper side 

 of the branchlet, but is marked below with X-shaped white markings, due to a 

 coating of wax on the inner margins of the lateral leaves and on both margins of 

 each ventral leaf. Leaves on the main axes oblong, unequal, the lateral \ in. 

 long, the facial \ in. long, with spreading rather obtuse tips. 



Staminate flowers yellow. Cones on the ends of short scaly branches, ripening 

 in the autumn of the first year, and falling in the following year, globose, \ in. in 

 diameter, orange brown when ripe ; scales eight, rarely ten, with the outer surface 

 depressed in the centre, from which arises a minute ovate appressed process. Seeds, 

 two to five on each scale, ovate, \ in. long, brown, with conspicuous large resin- 

 vesicles and narrow wings. 8 Seedling with two cotyledons, which are about \ in. 

 in length. 



Varieties 



This species has long been cultivated in Japan, where it has given rise to 

 numerous peculiar varieties.

3 Some seeds from a tree growing at Nikko have three wings, instead of the normal lateral two wings.
