Varieties 



In the wild state at Monterey, this species shows no variation, except the 

 marked difference in habit due to age, young trees being narrowly pyramidal, while 

 old trees assume a broad and flattened crown, resembling Lebanon cedars in their 

 general appearance. 



i. Var. guadalupensis, Masters, vajourn. Linn. Soc. {Bot.) xxxi. 343 (1896). 



Cupressus guadalupensis, Watson, in Proc. Amer. Acad. xiv. 300 (1879), and Engelmann, in Brewer 

 and Watson, Bot. Calif, ii. 114 (1880). 



This variety, growing on Guadalupe Island, differs slightly in the glaucous 

 leaves and globose cones. Specimens of this variety growing at Montpellier show 

 more slender branchlets and smaller leaves than typical C. macrocarpa. The 

 foliage has a bluish tint. A young plant in the Temperate House at Kew is 

 similar, but green in colour. 



Under cultivation, the Monterey tree tends to assume two distinct habits, 

 which are, however, connected by intermediate forms. Both have been found as 

 seedlings in beds raised from the seeds of a single tree : 



2. Var. fastigiata? Masters, loc. cit. Branches fastigiate ; tree narrowly pyramidal 

 in form. 



3. Var. Lambertiana? Masters, loc. cit. Branches spreading, the tree resembling 

 when old a Lebanon cedar. 



The following varieties 4 have also arisen in the seed-bed : 



4. Var. Crippsii, Gordon, Pinetum, 93 (1875). A plumose or juvenile form, 

 with short rigid branches, and leaves not appressed, but more or less spreading and 

 sharp-pointed. This variety was raised in Cripps' nursery at Tunbridge Wells 

 from an imported seed. 



5. Var. lutea, Kent, Veitch's Man. Coniferce, 215 (1900). Young shoots light 

 yellow, turning green in the second year. Earl Annesley, Beautiful Trees, 57 

 (1903), figures this variety 21 ft. high, planted eight or nine years previously; 

 and states that it is fastigiate in habit, strikes easily from cuttings, and preserves 

 its colour. 



6. Var. variegata? Young branchlets irregularly blotched with white. 



7. Var. farallonensis, Masters, in Journ. Linn. Soc. {Bot.) xxxi. 344 (1896). A 

 peculiar form reported to exist on the Farallones Islands, near San Francisco. 



1 Described by Hill and De Fraine, in Ann. Bot. xxii. 702 (1908). 



s Carriere states that the fastigiate form is much less hardy than the other. This must have been an accidental pecu- 

 liarity in a few trees noted by him. 



3 This form is said to be obtained artificially by topping off the leading shoots of ordinary seedlings. The tops, if 

 treated as cuttings and struck, assume also the flat-headed form. Such trees, obtained from cuttings, are said to be superior, 

 when this species is used for a hedge or wind-break. Cf. Card. Chron. xxvii. 44 (1900). 



4 In Card. Chron. 1872, p. 609, Messrs. Garroway, of Bristol, are said to have raised from seed a dwarf variety, 4 in. 

 high at nine years old.
