Trees or shrubs; leading shoot nodding; branchlets more or less flattened 

 and in flat sprays ; leaves opposite, in 4 rows, the successive pairs in ours unlike. 

 Catkins and cones very similar to Cupressus. Stamens with usually 2 pollen- 

 sacs. Ovules 2 to 5 at the base of each scale, the seeds winged, usually 2 (1 to 

 5). Cones maturing in the first autumn. Cotyledons 2. Six species, 3 in 

 North America and 3 in Japan. (Greek chamai, dwarf, and kuparissos,

1. C. lawsoniana Parl. PORT ORFORD CEDAR. LAWSON CYPRESS. Forest 

 tree 80 to 175 feet high, with straight shafts and narrow pyramidal crown 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 1^/2 to 2 lines long, narrowly 

 wing-margined on each edge, the whole 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 

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

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

 Co.), Klamath Range near Preston Peak, Three Creeks near Hupa Valley 

 (AV.L.J.), Trinity Center, and upper Trinity River between Coffee Creek and 

 Scott Mts., with a few trees on Graves Creek (Benj. Macomber). The tallest 

 of all cypresses. Wood very fine-grained, faint yellowish white, somewhat 

 aromatic, highly valued as a cabinet wood but the supply limited. Also 

 called Ginger Pine.

C. NOOTKATENSIS Spach. Nootka Cedar. Yellow Cypress. Bark thin, irregu- 

 larly fissured into flat ridges; branchlets not flattened; leaves alike, usually 

 not glandular. Northern Oregon to Alaska. 



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 upon short lateral branchlets, the ovules 

 numerous, erect, in several rows at the base of the scales. Cones globose 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. Northern hemisphere, 14 species. 

 (Ancient Latin name from Greek, kuparissos.)
