 Leaves in fives, but not unfrequently in fours, very dense, 

 six inches long, rather slender, curved, and of a dark green colour. 

 Sheaths long on the young leaves, but with a shrivelled appear- 

 ance on the old ones, and jagged at the ends. Branches few, 

 very robust, and irregularly placed on the stem. Cones growing 

 in clusters, pendulous, four or 'five inches long, and nearly two 

 inches broad ; oblong, tapering to the point, which is rather 

 blunt, incurved, and of a deep purple colour when young, and 

 dark-brown when fully matured. Scales flattened, broader 

 than long, four-sided, rather thin, with a projecting or elevated 

 bhort point in the centre, but much smaller towards the ex- 

 tremities ; narrower, and more elevated near the apex. Seeds 

 middle size, with very short wings, not more than three- 

 quarters of an inch long. 



A handsome tree, growing from 40 to 50 feet high, with a 

 dense compact head, of a fine dark green, found by Mr. Hartweg 

 on the Campanario Mountain^ in Mexico, at an elevation of 9000 

 feet, and beginning to appear where the Oyamel (Picea religiosa) 

 ceases to grow, on the mountain. It is also found on the moun- 

 tains of Orizaba, and near Eeal del Monte, at an elevation of 

 10,000 feet, and 100 feet high.
