15. CHAMAEBATIA Benth. 

 Low glandular-pubescent heavy-scented evergreen bush with dissected fern- 

 like foliage. Leaves thrice pinnate, with numerous minute leaflets and very minute 

 stipules. Flowers white, in loose terminal cymes. Stamens about 50 to 60 in sev- 

 eral rows. Pistil one, simple; style densely villous at base; ovule one. Fruit an 

 achene, included in the persistent calyx-tube. — Species 1. (Greek chamae, on the 

 ground, low, and batos, a bramble.) 



1. C. foliolosa Benth. Mountain Misery. (Fig. 166.) One to 2 feet high; 



leaf -blades obovate or ovate in outline, 1% to 4^2 inches long; leaflets crowded, 



% line long; calyx-tube glandular-hispid; calyx-lobes lanceolate, usually reflexed, 



about 2 lines long; petals obovate, 3 to 4 lines long; ovary 



more or less white-hirsute. 



Mountain slopes, 2000 to 6000 (or 7500) feet : Sierra Ne- 

 vada from Sierra Co. to Kern Co. May-July. 



Field note. — Chamaebatia foliolosa is commonly gregarious in the 

 open Pinus ponderosa forest of the main ridges in the Sierra Nevada, 

 reaching its greatest development from Nevada Co. to Mariposa Co. 

 Except for herbaceous or grassy vegetation it tends to form pure col- 

 onies which are often very extensive. On some mountain slopes its 

 growth is so even and uniform that at a distance a lawn-like effect is 

 produced. On such areas it discourages reproduction of forest tree 

 species and even grasses and similar herbs. On the South Fork Kaweah 

 Eiver it forms colonies under the tall chaparral. Cattle do not browse 

 its herbage ordinarily, though it may be cropped somewhat after frost. 

 Its balsamic or witch-hazel odor and tarry leaves make it well-known 

 to mountaineers who call it Pine Tar "Weed, Jerusalem Oak, Eunning 

 Oak, Bear Clover, Bear Weed, Bear Mat, as well as most commonly 

 Mountain Misery.
