Cupressus nivalis, Lindley, in Gard. Chron. 1855, p. 421. 



Cupressus glandulosa, Hooker, ex Gordon, Pinetum, 64 (1858). 



Usually a shrub with several stems, 5 to 10 ft. in height, rarely a small 

 wide-branching tree, attaining 40 ft. in height and 4 ft. in girth. Bark thin, 

 reddish brown, separating on the surface into long thin persistent scales. Branches 

 of the fourth and succeeding years smooth and purplish brown. Branchlet systems 

 arising irregularly and spreading at varying angles, tri-pinnate, with the pinnae not 

 disposed in one plane. Ultimate branchlets short, tetragonal, compressed, -fa to 

 fa in. wide, and j^ in. thick. Leaves $ in. long, appressed, ovate, thick, obtuse ; 

 lateral ranks conduplicate ; facial ranks convex from side to side and somewhat 

 flattened ; all usually marked on the back with a circular glandular pit, often 

 exuding resin. In native specimens, the foliage on the back and front is often 

 covered with white streaks, and is said to be very fragrant. 1 



Cones, ripening in the second year, erect on short stout stalks, globose, f to f 

 in. in diameter, reddish brown, more or less covered with a glaucous bloom ; scales 

 usually six, rarely eight, with prominent processes, those on the lower scales thin 

 and recurved, those on the upper scales thickened, conical, more or less incurved. 

 Seeds numerous, ten to twelve on each scale, dark brown, -|- in. long, with resin- 

 vesicles ; wings very narrow. 



C. Bakerii, Jepson, Fl. Calif. 61 (1909), of which I have seen no specimens, 

 appears to be a variety with small and very glaucous cones, the umbos of which are 

 short, conical, and not incurved. It is said to be a small tree growing on lava beds 

 in south-eastern Siskiyou and south-western Modoc counties. 



C. Macnabiana is a native of California and is common in the hill country of 

 eastern Napa County, from Samuel's Springs to Pope Valley, and extends north- 

 wards through Lake County to Red Mountain on the east side of Ukiah Valley 

 in Mendocino County. It also occurs in Trinity County between Shasta and 

 Whiskeytown. Carl Purdy 2 gives an interesting account of this species on Red 

 Mountain, on the eastern slope of which it forms a pure forest about half a mile 

 square, composed of old gnarled twisted trees, 12 to 20 ft. high, and covered with 



1 Miss Eastwood says that the fresh foliage has a delightful fragrance, somewhat like that of sandalwood with a flavour 

 of pine-apple. Carriere, in Rev. Hort. 1870, p. 155, compares the odour to that of pomme de Reinetle, and says that 

 branches cut and put in water purify the air of a room.
