t 



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



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

 spikes), often a foot long or more : leaves oblanceolate to obovate or orbicular, | 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 : staminate 

 spikes opposite or verticillate, usually shorter than the leaves, 3 - 7-jointed, the 

 numerous flowers mostly in 4 to 6 rows on each side and occupying 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. PL Lindh. 212. Viscum flavescens, Pursh, the com- 

 mon glabrate spatulate-leaved southeastern form. 



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

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

 R-jp. 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. PL Lindh. 212. 



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

 gon, anil eastward to New Mexico and Texas ; the former occurs on Populus, Platanm, Fraxinus 

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

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

 spikes. 



2. P. Bolleanum, Eichler. Puberulent, at length glabrous : branches 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 foul's, with connate minutely 

 ciliate bracts ; the staminate of two 61 2-flowered joints, the fertile of a single 2- 

 flowered joint : anthers transverse, opening by pores : fruit white, 1^ lines in diame- 

 ter. Fl. Bras. v 2 . 134 m . Viscum Bolleanum, Seem. Bot. Herald,"295, t. 63. P. 

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



On conifers, mostly Junipcrus, from the Geysers (Brewer} to San Felipe (Palmer) and into 

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

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



* * Leaves reduced to short mostly connate scales : spikes opposite, mostly 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. PL Garnbel, 185 ; Engelm. PI. Lindh. 213. 



Southern California and Arizona, on various Mimoscce and Cassieae, Larrea, etc. 



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

 high : brunches 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. PL 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 Juniperus, from Truckee Pass southward and through S. Nevada and 

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

 nardino.
