ENGELMANN AMER. JUNIPERS OF SEC. SABINA. 5S9 



about St. George, Utah, where the variety furnishes the common firewood, 

 it is a small tree 20 feet high; berries smaller, 3-5 lines long; cotyledons 

 same as in the species, never less than 4. Dr. Palmer has sent from the 

 Colorado River" a form with whitish, scaly bark, which I cannot otherwise 

 distinguish, but have seen no mature fruit of it. — The plant is often con- 

 founded with the stouter forms of y. occidentalis. but in fruit can always 

 be readily distinguished. 



2. jf. Mexicatia, Schlechtend. : A bush or (fide Parlatore) a pyramidal 

 tree; spray much more slender than the last, older branchlets with semi- 

 acerose, squarrose leaves; leaves o ultimate branchlets mostly in pairs, 

 slender, acute, irregularly denticulate; anther-scales in pairs (about 12) 

 strongly cuspidate or almost acuminate; scales of female anient about 

 2 pairs, spreading, rarely in 3's ; berry globose or oval, as large as and 

 similar to that of the foregoing species; seeds single or often 2 or 3, simi- 

 lar to the last. — Linnrea 5, 77 (1830); ib. 12,494. Parlat.'in DeProd.

Mexico. — The i-seeded form is Shlechtendal*s original, sent by Schiede 

 from Llanos de Perote ; Real del Monte, Hartiveg, 433. A 2-3 -seeded 

 form has been collected at the last locality by Ehrenberg (often with 

 protruding seeds) and Gregg, 636; in the Sierra Madre, Seemanu, 2001 ; 

 Cosiquiriachi, Wtsh'zenus, 230. — Most collectors describe this species as a 

 bush or small tree, but Parlatore assigns to it, without giving his author- 

 ity, a height, sometimes, of 70-90 feet; he gives the bark, as seccdcns, 

 shreddy. The slender branchlets, the acute, denticulate, not deeply 

 fringed leaves spreading on the older branchlets, and the regularly 2-coty- 

 ledonous embryo, distinguish it readily from the last. 



3. J. pachyphlcea, Torr. : A middle-sized tree with a spreading. 

 rounded top, thick and much cracked bark and pale reddish wood, closely 

 allied to the last, with the same squarrose leaves on the stouter branchlets, 

 but distinguished by the slenderer, acuter, less prominently denticulate or 

 ciliate leaves, usually in pairs, and by the obtusish anther-scales; berry 

 globose or irregularly tubercled, 5-6 lines thick; seeds mostly 4, angular.

 Greene. — Further examination must show whether it stands not too close 

 to the last; but the character of the bark seems to distinguish it completely 

 from that and any other species. In the report of Sitgreave's Expedition, 

 p. 12, this singular species is mentioned, and on page 173 Torrey gives a 

 short account of this and two other forms, without naming them. The 

 plate with the name of J. plockyderma, probably a mistake of the litho- 

 grapher for packy 'derma, gives a rough figure of our tree. 



4. J. flaccida. Schlectend. : A bush, or small or middle-sized tree with 

 shreddy bark, with spreading branches and slender, nodding branchlets; 

 leaves always in pairs, acute with spreading tips and slightly denticulate
