No. 27. Pinus brachyptera, Wislizenus, the Short Wing- 

 seeded Pine. 



Leaves in threes, but sometimes in twos, or fours, of a dark 

 green, and rough at the edges ; from three inches and a half to 

 to six inches long, and mostly in bunches at the ends of the 

 branches. Sheaths persistent, and nearly black when old. Buds 

 covered with regularly acuminated, membranaceous, fringed, 

 persistent scales. Branches horizontal. Cones rather erect, 

 ovate, oblong, or somewhat conical, from two and a half to 

 three inches long, and one inch and a half broad at the widest 

 part. Scales thickened at the base, elevated, recurved, and 

 spiny-pointed. Seeds three or four lines long, and two lines 

 broad. Wings shorter than the seeds. 



A handsome tree, growing from eighty to a hundred feet 

 high, and two to three feet in diameter ; found abundantly by 

 Messrs. Wislizenus and Engelmann, on the mountains of New 

 Mexico, producing excellent timber. 



No. 28. Pinus Bungeana, Zuccarini, the Chinese Lace-bark

 three-edged. Sheaths composed of numerous loose scales, which 

 soon fall off, and leave the base of the leaves naked. Buds non- 

 resinous, and formed of several reddish-brown, smooth, fringed 

 scales, largest at the base, and rough at the edges. Male cat- 

 kins from five to six lines long, cylindrical, or conical ; and when 

 young placed alternately at the base of the young shoots, in 

 clusters, but frequently afterwards very distant, owing to the 

 rapid elongation of the youngshoots. Branches long, very slen- 

 der, little divided, glaucous, and covered with a smooth gray bark, 

 rendered a little rough on the stem and older branches by the
