branchlets and short branchlet systems, which give a rigid habit to the tree ; and 

 (b) the following variety : 



1. Var. attenuata, Carriere, Com/. 172 (1867). 



Cupressus attenuata? Gordon, Pinetum, 57 (1858). 



Characterised by looser branching, with longer branchlet systems, and very 

 slender ultimate branchlets, about g\y in. in diameter. Leaves ^ in., swollen 

 towards the apex, which is tipped with a minute mucro. Two kinds of seed are 

 produced, as in the typical form. This variety is said by Gordon to have been 

 introduced by French collectors ; but as seen in cultivation, it appears to be a 

 seminal variety, and is commoner than the type. 



2. Var. pendula. 



Cupressus calif ornica, Carriere, Com/. 127 (1855). 



A shrub, pendulous in habit, with long and slender drooping branchlet systems, 

 some of the branchlets being covered with spreading sharp-pointed leaves. This 

 appears to be a transition form between the seedling and adult stages. A plant 

 of this variety, cultivated under the name C. californica, Carriere, is growing in 

 M. Allard's arboretum at Angers ; and another specimen occurs at Kilmacurragh 

 in Co. Wicklow. 



The following is considered by Sargent to be a distinct species, but, so far as 

 we can judge, the variation in the seed is sporadic, and depends upon unknown 

 conditions, which should be studied in the field. 



3. Var. pygmcea, Lemmon, W. Amer. Cone-bearers, yy (1905). 



Cupressus pygmaa, Sargent, in Bot. Gaz. xxxi. 239 (1901), Silva. JV. Amer. xiv. 95, t. 740 (1902), 



and Trees N. Amer. 79 (1905); Eastwood, Trees 0/ California, 18 (1905). 

 Cupressus Goveniana, Jepson, Flora Calif 60 (1909) (not Gordon). 



A name given to trees bearing cones with small blackish seeds. This variety 

 is prevalent near Monterey ; and occupies a narrow belt in Mendocino County, 

 California, beginning three-quarters of a mile from the ocean, and extending inland 

 for about four miles from Ten Mile Run in the north to Navarro in the south. It 

 is said to remain shrubby as a rule, producing fruit when only one or two feet high, 2 

 and grows commonly on poor soil, consisting of yellow clay covered with sand or 

 peat ; but it is admitted by Miss Eastwood to attain on good soil 30 or 40 ft. in 

 height at fifty years old. 



The typical form of C. Goveniana is rare and local, apparently uncommon in 

 the coast region of California, though it was found by Hartweg 3 at Monterey, and 

 usually grows on dry mountain slopes, ascending in the canons of the mountain 

 ranges of the central part of the state to nearly 3000 ft. Jepson, 4 who says it is a

3 Hartweg's specimen, No. 197 1, in the Kew Herbarium, collected at Monterey, has large brown seeds, and is the type 

 on which Gordon, who states that the seeds are brown, founded his description. Jepson, in Flora California, 60, 61 (1909) 

 erroneously considers the form with small black seeds to be typical C. Goveniana : and on this account invents a new name, 

 C. Sargenti, for the true C. Goveniana with large brown seeds, lioth forms occur at Monterey, as Hartweg's specimen, 

 No. 1979, preserved at the Cambridge Herbarium, was collected there and bears cones with small black seeds.
