* Leaves follaceous, viostbj dilated upward from a narrow base. 



1. P. flavescens, Xutt. Branches terete, pubescent when young (as also the 

 spikes), often a tuot long or more : leaves oblanceolate to obovate or orbicular, i to 2 

 inches long, obtuse, 3-nerved, at last glabrous : bracts connate into a short truncate 

 cup : flowers depressed-globose, the calyx-lobes ciliate on the margin : staniinate 

 spikes opposite or verticillate, usually shorter than the leaves, 3 - 7-jointe(l, the 

 lunnerous Howers mostly in 4 to G rows on each side and occuitying nearly the 

 whole joint, very fragrant with the odor of pond-lilies ; anthers transverse, opening 

 by 2 pores : pistillate spikes usually opposite, shorter (rarely 5 - 6-jointed), the flow- 

 ers (2 to 7 on each side of a joint) in not more than three series : berries white, 2 

 lines in diameter. — Engelm. PI. Lindh. 212. Viscum flavescens, Pursh, the com- 

 mon glabrate spatulate-leaved southeastern form. 



Var. macrophyllum, Engelm. Leaves large (2 to 2h inches long), broad, 

 often 5-nerved, glabrate : flowers larger, in stout short jointed spikes. — Wheeler's 

 E3p. vi. 252. 



Var. villosum, Engelm. 1. c. Leaves small or middle-sized, orbicular to spatu- 

 late, permanently pubescent or tomentose : spikes slender, rather short. — P. vil- 

 losum, Nutt. 1. c. ; Engelm. PI. Lindh. 212. 



The latter variety is common thvoughout the State, chiefly on oaks, from S. CaHfornia to Ore- 

 gon, and eastward to New Mexico and Texas ; tlie former occurs on PopiUus, Plataniis, Fraxmus 

 and other trees, from S. California to New Mexico. Var. tomentcsum {Viscum tomentosum, DC.) 

 is found in Northern Mexico, on Mimosccc, and is densely tomentose, with slender elongated 

 spikes. 



2. P. BoUeanum, Eichler. Puberulent, at length glalu-ous : l^ranches terete, 

 less than a span long : leaves thick, spatulate to linear, 6 to 12 lines long by 1 to 3 

 wide, nerveless, obtusish : spikes opposite or rarely in fours, with connate minutely 

 ciliate bracts; the staminate of two 6- 12-flowered joints, tlie fertile of a single 2- 

 flowered joint : anthers transverse, opening by pores : fruit white, 11 lines in diame- 

 ter. — Fl. Bras. v^. 134'". Viscu7n BoUeanum, Seem. Bot. Herald,"'295, t. 63. F. 

 pauciflorum, Torrey, Pacif. E. Rep. iv. 134. 



On conifers, mostly Junipcrm, from the Geysers {Brewer) to San Felipe {Palmer) and into 

 Arizona and Mexico ; also on Guadalupe Island, Palmer. A specimen on Abies concolor, from 

 DnlHeld's Ranch near Auburn (Bigelow), is larger and with larger broader leaves. 



1= * Leaves reduced to short mostly connate scales: spikes opposite, most/ >/ few- 

 flowered. 



3. P. Californicum, Nutt. Pubescent or at last glabrous : branches terete, 

 slender, a foot or two long : scales broadly ovate, acute, spreading : staminate spikes 

 of 2 or 3 (rarely 5) flower-bearing joints, each with 2 to 6 ovate-subglobose flowers : 

 anther-cells oblong, opening by a longitudinal slit : fertile spikes sometimes with 

 nearly as many joints and flowers, the joints elongated (often an inch long) in fruit : 

 berries reddish, 2 lines wide. — PI. Gambel, 185 ; Engelm. PI. Lindh. 213. 



Southern California and Arizona, on various Miinosece and Cassicce, Larrca, etc. 



4. P. juniperinum, Engelm. Glabrous, stout, densely branched, 6 to 9 inches 

 high : branches terete, the ultimate branchlets (quadrangular : scales broadly triangu- 

 lar, obtusish, connate or distinct, ciliate : staminate spikes of a single 6 - 8-flow- 

 ered joint (rarely two) : anthers transverse, opening by pores : pistillate spikes 2- 

 flowered : berry globose, whitish or light red, 1^ lines wide. — PI. Fendl. 58. 



Var. Libocedri, Engelm. Branches a foot long or more, slender : joints more 

 elongated, the ultimate ones more sharply quadrangular. 



On different species of Jmiiperus, from Truckee Pass southward and through S. Nevada and 

 Arizona to New Mexico ; the variety on Libocedrus decurrcns, from tlie Yuba River to San Ber- 

 nardino.
