tuon, network, referring to the dense felt covering the lower surface of the 

 leaves between the very prominent net-work of veins. 



Field Guide to the Species 



Herbage white-woolly; leaves not glutinous above; flowers in dense, leafy, more or 



less head-like clusters 1. E. Lohbi. 



Herbage not white-woolIy ; leaves more or less glutinous above; flowers in branched 

 spreading clusters, the clusters with few leaves. 

 Leaves oblong to lance-shaped, 2 to 8 inches long, the margins very slightly, if 



at all, inrolled; occurs in Califorina parks 2. E. calif oriiicum. 



Leaves linear, 1 to 4 inches long, the margins conspicuously inrolled; occurs in 



the Southwest parks 3. E. an gusli folium. 



\. Woolly Yerba-santa {Eriodictyon Lobbi (Gray) Greene). — Low 

 spreading shrub, 1/2 to I1/2 feet high, the stems creeping or somewhat erect; 

 lower leaves % to 1 inch long, linear or narrowly spatula-shaped, white- 

 woolly at least below, the margins more or less inrolled, crowded and bunched 

 along the stems; leaves of flowering stems 1 to 2 inches long, spatula-shapeid, 

 scattered on the stems; flowers purple, tubular, about 1/3 to 1/2 inch long, 

 borne in clusters of a few in the axils of the upper leaves; fruits tiny capsules 

 splitting into 4 sections. (Syn. Nama Lobbi Gray) . 



Occurrence. — LASSEN : Lassen Peak. 



2. California Yerba-santa (Eriodictyon calijornicum H. & A. 

 Greene) . — Erect evergreen shrub 2 to 8 feet high; leaves oblong to lance- 

 shaped, 2 to 8 inches long, smooth and usually somewhat sticky or varnished- 

 looking above, densely grayish-felty below, the margins shallowly toothed 

 and sometimes slightly inrolled; flowers with tubular corollas, % to % inch 

 long, blue to lavender or almost white; fruits small hard capsules about Yg 

 inch long, splitting into 4 sections. 



California yerba-santa is considered a valuable honey plant for bees and 

 the herbage is browsed to a certain extent by deer. Early settlers considered 

 the crushed leaves as helpful in treatment of colds, catarrh, and asthma. 



Occurrence. — YOSEMITE, occasional, 2,500 to 5,000 feet: west entiance to park; 

 Mirror Lake; Wawona. SEQUOIA, occasional, 2,000 to 6,000 feet: Giant Forest; 

 Marble Fork Kaweah River. 



3. Narrowleaf Yerba-santa (Eriodictyon angusttfolium Nutt.). — 

 This species differs from California yerba-santa in having the leaf margins 

 inrolled to form linear leaves. The leaves also tend to be bunched along 

 the stems more than in the California species. 



Occurrence. — ZION : j/2 mile north of Silver Reef Mine. 



Verbena Family (Verbenaceae) 



Wright Lippia (Lippia Wrighti Gray). — Erect aromatic shrub, 2 to 4 

 feet high, with widely spreading opposite branches; bark of young stems
