 A small shrub ; flowers in July. 



Ceanothus thyrsiflorus Esch. Blueblossoni. 



Range: 1. 



Site : Dry, well-drained, sun, shade. 



Fruit : Capsule, available July-December. 



A large shrub to small tree ; evergreen ; flowers April-June ; nitrogen nodules 

 very abundant ; forms dense thickets after fires ; a pioneer in cut-over areas, 

 often to the exclusion of other species ; not successful in heavy soils ; root 

 system shallow ; 83-percent germination of seed obtained by treating in hot 

 water to 158 F., cooling, and stratifying 3 months at 36 ; about 182,000 seeds 

 per pound. 



Observations: An important food of Roosevelt elk. 



Ceanothus tomentosus Parry. lone bush. 



Range: 4. 



Site: Dry, well-drained, sun. 

 Fruit : Capsule. 



A large, loosely-branched shrub ; flowers in May ; occurs up to 3,000 feet ; 

 stump sprouts after cutting. 



Var. olivaceus Jeps. (C. cyaneus Eastw.), Ramona bush, occurs in region 5. 

 Observations: Of slight importance as browse for mule deer. 



Ceanothus velutinus Dougl. Snowbrush. 



Range : 2, 4, 6, 7, 12, 13, 15. 

 Site: Dry, sun. 

 Fruit: Capsule. 



A small to large evergreen shrub; flowers May-July; spreading and many 

 stemmed from the base; possesses a single large taproot which may make 

 transplanting difficult ; root system spreading, deep ; a pioneer, forming vast 

 thickets in logged or burned-over areas ; 68 percent germination of seed is 

 obtained by treatment in hot water at 176 F., and stratification for 3 months 

 at 36, or 63 percent when boiled 5 minutes and stratified 3 months. 

 Stomach records: Plains white-tailed deer. 



Observations: A fair browse for mule deer ; pica. Usually grazed only 

 slightly by stock ; much grazing indicates poor range ; attempts to eradicate 

 the species by overgrazing by goats have failed. 



Ceanothus verrucosus Nutt. Barranca bush. 



Range: 5. 



Site : Dry, sun. 



Fruit: Capsule. 



A small to large, wide-spreading shrub ; flowers January-April ; occurs in 

 sandy soils, not successful in heavy soils ; 20-percent germination of seed 

 obtained when sown directly. 



Ceanothus vestitus, see Ceanothus greggii. 

 Cebatha Carolina, see Cocculus carolinus. 

 Cebatha diversifolia, see Cocculus diversifolius. 



Celastrus scandens L. Climbing bittersweet. 



Range : 11, 15, 16, 18, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30. 

 Site: Dry, well-drained, sun, shade. 

 Fruit: Pod, seeds with pulpy arils, available September-December, 



rarely later. 



A twining, high-climbing, or thicket-forming vine ; essentially dioecious but 

 pistillate plants have enough staminate flowers to ensure fertilization ; injures 

 trees by constriction ; very common along fence rows ; occurs in loam, sand, 

 clay, and other soils; propagation is by seeds sown in fall or stratified and 

 sown in spring, or by layers and root cutting; 12,000 seeds per pound, germi- 

 nation 80 percent, about 3,000 usable plants per pound of seed. 



Stomach records: Eight species of birds, including ruffed grouse and bob- 

 white. 



Observations: Seven species of birds, including ring-necked pheasant; cotton- 

 tail rabbit, fox squirrel, songbirds. Not browsed by livestock ; poisonous to 

 horses but apparently not attractive to them.
