one which at the same time extends through so many degrees of 

 latitude. It is well known from the St. Lawrence to the Cedar 

 Keys of Florida, from the Atlantic to the Rocky Mountains ; and 

 farther, even to the Pacific coast of British Columbia. 



I arrange the eight American species in the following order : 



I. Sabin.e, with larger, reddish-glaucous, fibrous, dry, sweetish berries. 



a. Seeds single or few; leaves fringed or denticulate. 



a. Cotyledons 4-6. 



1. J. Californica. 



b. Cotyledons 2. 



2. J. Alexicana. 



b. Seeds numerous, 4-12; leaves slightly denticulate. 



3. J. pachyphhva. 



4. J. flaccida. 



II. Sabin.e, with smaller, bluish-black (rai-ely brown) pulpy berries, of 

 resinous taste. 



a. Leaves ciliate or denticulate. 



5. J. occide?iialis. 

 5*. J. conjungens. 



6. J. tctragona. 



b. Leaves entire or nearly so. 



7. J. Sab in a. 



S. J. Virgin in 11 a. 

 9. J. Bermudiana. 



1. J. Californica, Carriere : A stout shrub, or small tree (rarely 20 to 

 even 35 feet high) with stout branches, the branchlets perhaps the thick- 

 est of any Sabina : leaves almost always in 3's, in young shoots acerose, 

 white above, in adult plants, even on the thicker branches, closely appres- 

 sed, short and thick, rounded at tip, distinctly cartilaginous-fringed on 

 the margins ; anther-scales (18-24) mostlj' in 3's, rhomboid, scarcely acute ; 

 scales of female ament usually 6, spreading; berry globose or mostly oval, 

 5-6 lines long, with scale-tips scarcely prominent; seeds 1 or sometimes 2, 

 4-6 lines long, with a very thick and hard shell, smooth, shining brown 

 above, with large bilobed whitish hilum. — Rev. Hort. 3, 352 (1854);

 Rep. 4, 141; Bot. Mex. Bound. 210. J. Cerrosiamis, Kellogg, Proc. Calif. 

 Acad. 2. 37, fide spec, auctoris in Herb. Torrey. (See Fig. 1.) 



Var. Utahensis : In all the parts smaller, leaves and tips of fruit-scales 

 often in pairs, fringe of leaf-margin shorter; berries more commonly glo- 

 bose; seeds mostly single, smaller. 



California, from San Francisco (Monte Diablo) southward, principally 

 on the Coast range and on the Islands ; the variety all over the southern 

 parts of Utah and into Arizona and Nevada. — Bark shreddy, wood pale;
