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

 numerous flowers mostly in 4 to G 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 - G-jointcd), the flow-

 mon glabrate spatulatc-leaved southeastern form. 



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

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

 late, permanently ])ubescont or tomentose : spikes slender, rather short. — P. vil-

The latter variety is common thiouf^hout the State, cliiedy on oaks, from S. California to Ore- 

 gon, and eastward to Nmv Mexico and Texas ; tiie former oo(;urs on PopuJm, Platanus, Fraxinus 

 and otlier trees, from S. California to New Me.xico. Var. 'roMENTOSiTM {Fisciim (omenlosum, DC.) 

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

 spikes. 



2. P. Bolleanum, Eichlcr. 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 op[)osite or rarely in fours, with connate minutely 

 ciliate bracts; the staniinate of two G- 12-flowercd joints, the fertile of a single 2- 

 flowered joint : anthers transverse, oiiening by pores : fruit white, li lines in diame- 

 ter. — Fl. Bras, v^ 134"". TiV^wt Bnlleannm, Seem. Dot. Herald, "295, t. 63. P. 

 paucijlorum, Torrey, Pacif. li. Pep. iv. 134. 



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

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

 DuIField's Ranch near Auburn (Bigcloir), 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 ;■ staniinate 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 Mimosca: and Cassicce, Larren, etc. 



4. P. juniperinum, Engidm. Glabrous, stout, densely branched, G to 9 inches 

 bigh : branches terete, tlio ultimate branchlets <piadrangtdar : scales broadly triangu- 

 lar, obtusish, connate or distinct, ciliate: staniinate spikes of a single G-8-flow- 

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

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



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

 elongated, the ultimate ones more sharply quailrangular. 



On difTorent species of Juiu'pcric.i, from Truckee Pass sotithward and through S. Nevada and 

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