24 CUPRESSACEAB. 



mon: Santa Lucia, San Carlos and Mi. Hamilton ranges; Mt. St. Helena and 

 north to Mi. Shasta. Wood very durable. When the cone is dead ripe the 



septal scale usually separates partially into •'! scales; these scales are quite 

 distind III the young catkin and the central scale is then seen to consist of a 



completely blended reduced pair. The ovulate catkin consists, therefore, of 

 1 pair of scales, the firsi pair barren, the second pair ovule-bearing, the third 

 and fourth pair becoming in fruit completely united to form the "septal scale.'' 



2. CUPRESSUS L. Cypress. 



Trees or shrubs. Leaves scaledike, small, appressed, closely imbricated in 

 four ranks on the ultimate cord like branchlets, or awl-shaped on vigorous 

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

 to each stamen. Ovulate catkins on short lateral branchlets, the ovules numer- 

 ous, 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 margined; cotyle- 

 dons 2 to 5. (Classical name of the Cypress.) 



Umbos small and low. 



Branchlets slender, squarish 1. C. goveniana. 



Branchlets thickish, terete 2. C. sargentii. 



Umbos prominent, the two uppermost horn-like and incurved; leaves with conspicuous 

 resin pits 3. C. macnabiana. 



1. C. goveniana Gord. Gowen Cypress. Shrub, compactly branched, 5 

 to 15 ft. high; foliage yellowish; ultimate branchlets very slender, squarish, 

 their leaves rarely with pits or lateral depressions ; cones light brown, sub- 

 globose or oval, 6 to 8 lines long, rarely lunger, with 4 pair of scales; umbo 

 short, crescent-like; seeds commonly black, sometimes brown but not red, angu- 

 lar or acutely margined, minutely warty, 1 to iy 2 lines long. 



Monterey, in the forest of Pinus radiata on the west slope of the Pt. Pinos 

 ridge. Often bearing cones when only one foot high in a manner similar to 

 the form of the Mendocino White Plains (C. pygmaea Sarg.), which also has 

 black seeds (less obviously warty) and leaves with few or no pits. 



2. C. sargentii Jepson. Shrub or tree, with larger red or reddish brown 

 often glaucous seeds; Leaves more commonly pitted; branchlets thickish, terete; 

 cones 8 to 1 1 lines long. 



Bed .Mt., Mt. Tamalpais, Cedar Mt. and near Bonny Doon. 



('. m \( IBOCAEPA Ilartw., Monterey Cypress, is restricted to the sea-cliffs at 



the month of the Carmel River near Monterey. 



3. C. macnabiana Mnrr. MACNAB CYPRESS. Shrub or small tree, com- 

 monly (i to s but ever 35 ft. high; branchlets very slender; Leaves with a con- 

 spicuous resin pit or white gland on the back towards the apex, often slightly 

 glaucous; cones globose, clustered, short -peduncled. 5 to 8 lines in diameter, 



reddish or grayish brown; scales 6 to s . with strong conical umbos, the upper- 

 mos1 very prominenl or horn like and incurved; seeds brown. 



Dry hills or tints; North Const Ranges from Samuels Springs, Mt. Aetna, 

 Red Mt., and Bartletl Creek north to Whiskeytown (Shasta Co.). Foliage blue- 

 green, pungently aromatic. 



3. JUNIPERUS L. Juniper. 



Trees or shrubs. Leaves in whorls of •"> or opposite, scalelike, imbricated, 

 closely appressed and adnate to the branchlets, or linear subulate and spread-
