590 TRANS. ST. LOUIS ACAD. SCIENXE. 



margins; male flowers quadrangular, narrow, consisting of 16-20 keeled 

 cuspidate anther-scales : large (6-7 lines thick) globose or often irregularly 

 tubercled berry, mostly with recurved acute scales, containing S-12 seeds 

 in several tiers ; seeds small, much distorted, many of them abortive. — 

 Linnaea 12, 495 (1838); Parlat. 1. c. 492. (See Fig. 4.) 



Mexico, Ehrenberg and others; Coulter, 1419; Saltillo, Gregg, 432, a 

 shrub, 10 feet high. —Well distinguished by its slender branchlets and 

 acute, mostly somewhat spreading leaves. 



5. J. occidentalis, Hook. : A shrub, or mostly a small tree (in Oregon 

 of the largest dimensions^ with shreddy bark and pale reddish-yellow 

 wood; closely appressed leaves in 3's or often in pairs, obtuse or acutish. 

 delicately fringed on the edges ; anther-scales obtusish or short-cuspidate ; 

 berries 4-5 lines in diameter, with 1 or more seeds. — Hook. Fl. Bor. Am. 

 2, 166 (1S40) ; Pari. 1. c. 4S9. (See Fig. 5.) 



Var. a. pleiosperma with straighter, stouter branchlets, leaves almost 

 alwavs in 3's ; berries larger (4-5 lines diam.), very resinous, deep black- 

 blue, with 2-3 much grooved seeds. — y. excelsa, Pursh. Fl. 2, 647, not. M. 

 Bieb. y. Andina, Nutt. Sylv. 3, 95, t. no. 



Oregon to the higher mountains of California, in the north sometimes 

 a large tree (Lewis, Douglass, Newberry), generally smaller or bushy; 

 if without fruit, it is not always easily distinguished from y. Californica 

 which Parlatore unites with it; the margin of the leaf is much like that 

 of var. Utahensis of that species, but the fruit is very different. 



Var. ,3. monosperma, a shrub or small tree, often with eccentric layers 

 of wood (Canon City, Colorado), of scraggy growth, with short branchlets 

 at right angles; leaves as often in 2's as in 3's; berries smaller, with 2 or 

 more, commonly only 1, less grooved seed. 



From the Pike's Peak region of Colorado through West Texas and New 

 Mexico to Arizona and California, where var. a takes its place. — In Colo- 

 rado the berries are often copper colored, as Parlatore describes those of 

 the species, and in some trees the seeds protrude. 



Var.? }. conjungexs, a bush or tree 20-40 feet high, often with eccentric 

 layers of wood; branchlets slender, with 4-ranked, obtuse, closely appres- 

 sed, slightly denticulate leaves: anther-scales obtuse or slightly cuspidate; 

 berries globose, 3-4 lines thick, with 1-2 smooth or more or less tuber- 

 culate seeds. (See Fig. 5*.) 



West Texas, where it forms forests and is an important timber tree, 

 "although not as large nor as easily worked and useful as the red cedar of 

 the plains of Eastern Texas" (F. Lindheimer). Berlaudier, 671, 2081; 

 Lindhcimer, Wright. Bigelozv, Hall. — Mr. Chas. Wright found in the 

 damp rocky woods of the mountains of Eastern Cuba a few individuals of 

 a middle-sized tree, apparently very rare, of which only male specimens 

 were obtained (PI. Cub. 3187, y. Vtrginiana, Griseb. PI. Cub. 217), which 

 without fruit I cannot distinguish from this Texan form; what I take to 

 be the same thing, has been sent from Mexico by Sartorius in Hb. Torrey, 

 and by Aschenborn from Zimapan, 381, in the Berlin Herb.; the latter
