 tree 80 to 175 feet high, with straight shafts and narrow pyramidal crowm of 

 drooping branches ending in broad flat drooping fern-like sprays ; bark brown 

 or somewhat reddish, smooth on young trees, later parting on the surface into 

 large loose thin shreds and finally in adult trees fissured longitudinally with the 

 furrows continuous and separated by flat ridges ; foliage fragrant ; leaves ad- 

 pressed, scale-like, thickly clothing the branchlets, disposed in opposite pairs, 

 those above and below rhomboidal, glandular-pitted, and overlapped by the 

 keel-shaped ones on the margin ; staminate catkins crimson ; cones globose, 

 consisting of about 7 scales, 3 to 4 lines long ; seeds li/^ to 2 lines long, narrowly 

 wing-margined on each edge, the Avhole structure orbicular. 



Moist hillsides or canon bottoms from Coos Bay, Oregon, southward to 

 Mad River and eastward to Halls Gulch, Trinity Co., and the Sacramento River 

 Caiion from Slate Creek to Shasta Springs. Occurs in California only in 

 isolated patches as at Quartz Creek and Shelly Creek bottom (Del Norte

4. CUPRESSUS L. Cypress. 



Trees or shrubs with the leaves small and appressed, scale-shaped and closely 

 imbricated in 4 ranks on the ultimate branchlets, or awl-shaped on vigorous 

 shoots. Staminate catkins terminal on the branchlets, with 3 to 5 pollen-sacs 

 to each stamen. Ovulate catkins tii)on short lateral branchlets. tlie ovules 

 numerous, erect, in several rows at the base of the scales. Cones gloI)ose to 

 oblong, maturing in the second year, the shield-shaped scales fitting closely 

 together by their margins, not overlapping, separating at maturity, their 

 broad summits with a central boss or short point. Seeds acutely angled or 

 with a narrow hard wing; cotyledons 2 to 5. — Nortli(M-ii hemisplu^rc. 14 species.
