208 A HANDBOOK OF CONIFER.E 



This species may be recognized by its slender, compressed 

 branchlet systems and minute, blunt or rounded, glandular 

 leaves and conical cone scales. 



C. Macnabiana is a native of California, where it is found on 

 dry hiUs or in the bottoms of canons from Napa County to Shasta 

 County eastward to the Northern Sierras, and westward to the 

 coast ranges. It was introduced into England in 1854 by 

 Messrs. Veitch, but old trees are seldom seen, and it appears to 

 have almost gone out of cultivation. It is apparently a short- 

 lived tree. 



Although the wood of wild trees appears to be of good quality 

 it is small and has no definite commercial value. 



This cypress is suitable only for the milder parts of Britain. 



Cwpressus Bakeri, Jepson.^ This tree appears to differ only 

 from C. Macnabiana in its smaller, glaucous cones, with smaller, 

 less prominent umbos.

Cupressus Hartwegii, Carrierc; C, Rsinwardtii, Beissner. 



A tree attaining in California a height of 70 ft. and a trunk 

 girth of 20 ft., the branches ascending and forming a conical 

 crown, or flat-topped like that of a Lebanon cedar with dense 

 masses of foliage. Bark thick, reddish brown at first, becoming 

 nearly white on older, exposed trunks, divided into flat, scaly 

 ridges. Branchlets alternate, ascending, spreading at various 

 angles, bipinnate, the ultimate divisions numerous, rather slender, 

 four-sided. Leaves scale-like, triangular, closely pressed, 5^4-^ 

 in. long, blunt at the apex and slightly swollen towards the 

 tip, sometimes furrowed on the back. Male flowers yeUow, | in. 

 long, stamens 6-8. Female flowers with reflexed, thin-edged 

 brownish scales. Mature cones sub-globose, 1-1| in. long, |-1 in. 

 broad, shining brown ; scales 8-14, flat-topped, with a central 

 crescent-shaped projecting process. Seeds about 20 on each 

 scale, ..V-tV ill- loiig' irregular in shape, narrowly winged, with 

 minute resin tubercles on each surface. Cotyledons 3-4. 



Under cultivation C. macrocarpa is known by two more or 

 less distinct types which are connected by intermediates ; both 

 forms have been raised from the seeds of one tree. They are : — 



Var. fastigiata, Masters. 



Branches fastigiate, forming a tree of narrowly pyramidal 

 habit.
