The average circumference of eleven of the largest trees 

 growing in the gulches visited was 11 inches, the extremes 

 being 15 and 7 inches. The naked trunk is short, as the limbs 

 begin not far from the ground, and the limbs themselves are 

 rather sparse, seldom over eight feet long, spreading, or 

 somewhat ascending, but not in the least pendulous. The 

 bark is smooth and shining, free from resin or fibers, of a 

 mahogany-brown color, with lighter mottlings, caused by the 

 scaling- off of thin flakes. Foliage bright green ; mature leaves 

 broadly triangular, 1 mm. wide; dorsal pits minute or mostly 

 wanting, without lateral furrows. Staminate aments numer- 

 ous, 3-4 mm. long, 2 mm. thick; anthers 4 to each scale. 

 Cones globose, 1.5-2 cm. in diameter, dark gray, densely clus- 

 tered, or rarely solitary; peduncles 1-5 cm. long; scales 6 

 (rarely 4-5), quadrate, 1.5 cm. in diameter, rugose, the umbo 

 blunt or having a small upturned scale-like point ; seeds about 

 70 in a cone, 4 by 3 mm., narrowly margined, minutely papil- 

 late, brown, and at base marked with a short white line. At 

 the time of my visit, October 13, a few trees were beginning 

 to discharge pollen, and most were nearly ready to do so, but 

 no pistillate catkins were noted. The seed of the previous 

 vear was mature, but the cones showed no tendency to open. 

 They were confined almost entirely to the larger trees. 



A second station for this Cypress is on the north face of 

 a mountain between Descanso and Pine Valley, about 20 miles 

 in an air line from Tecate, and 45 from San Diego. So far 

 as can be learned from those best acquainted with the region 

 these two stations are the only ones in any part of San Diego 

 county, or of Lower California. 



Although the existence of this Cypress has been long 

 known, there has been little definite information concerning 

 it, and its systematic disposition remains unsettled. In the 

 Botany of the Geological Survey (vol. 2. p. 114, 1880) \A/atson 

 included it in Cupressus goweniana, and he has been followed 

 bv Sargent (Sylva X. Am., vol. 10, p. 107. 1896) and by Sud- 

 worth (Forest' Trees Pac. Slope, p. 161. 1908). In Abrams 

 Trees and Shrubs of Southern California (Bull. N. Y. Bot. 

 Card, vol. 6, p. 330. 1910) it is referred to C. guadalupensis, a 

 species erected bv Watson for an endemic tree of the Mexican 

 island whose name supplied the specific adiective. Jepson, m 

 his Flora of California (pt. 1, p. 61. 1909) proposed a new 

 species, C. sargentii, for a certain shrub or small tree which 

 grows in isolated groves near the coast from Mendocino to 

 the Santa Lucia mountains, and in the Sylva of California 

 (Mem Univ. Cal. vol. 1, p. 158. 1910), he with hesitation 

 includes the San Diego trees in it. While these do not in all 

 respects agree with the characters defined for C. sargentu, this 

 disposition is the most satisfactory yet made. Phytogeograph- 

 ically the San Diego tree is not in harmony with the distribu- 

 tion of the genus on the Pacific Slope.
