Bailey sc Bailey: Woody Plants of National Parks

pink, borne in compact clusters at the ends of the branchlets; branches of 

 flowering clusters sticky-glandular; berries globose, y^ to 1/3 inch in diameter, 

 very sticky, becoming bright red (or whitish in var. bivisa) ; nutlets ridged on 

 the back, distinct or some of them united. 



Mariposa manzanita is very similar in appearance to whiteleaf manzanita, 

 the most noticeable difference being in the branchlets which are very glandular- 

 hairy in Mariposa manzanita and smooth or mostly without hairs or glands 

 in whiteleaf manzanita. The bushes of both are very striking in appearance, 

 the whitish leaves making quite a contrast to the reddish-brown stems. The 

 plants do not sprout from the root crown. 



A variety with whitish nutlets (var. bivisa Jepson) has been found at 

 Hetch Hetchy and at Wawona in Yosemite National Park. 



Occurrence. — yosemite, abundant, 3,000 to 6,000 feet: western park boundary at 

 Lake Eleanor; Hetch Hetchy Valley; Big Oak Flat road; El Portal; talus slopes on 

 north side of Yosemite Valley; near foot of Yosemite Falls; Royal Arch Falls; south 

 of Wawona. KINGS CANYON : switchbacks on Bubbs Creek trail. 



3. Whiteleaf Manzanita (Arctostaphylos viscida). — Same as for 



Mariposa manzanita except as noted above. 



Occurrence. — SEQUOI.A, common, 1,600 to 5,000 feet: Yucci Point, northwest cor- 

 ner of Park; Marble Fork Kaweah River; along General's Highway above Ash 

 Mountam. 



4. Greenleaf Manzanita (Arctostaphylos patida Greene), fig. 112. 

 — Shrub 3 to 8 feet high, with crooked, widely spreading branches, the 

 younger branchlets commonly very finely hairy and somewhat sticky; leaves 1 

 to 2 inches long, bright green, smooth, 



roundish to broadly elliptic, rounded or 

 pointed at the tip; flowers pink, on 

 smooth slender stalks 1/6 to I/4 inch 

 long, borne in dense flattish clusters 

 towards the ends of the branches; ber- 

 ries light brown or black, smooth, round- 

 ish, 1/3 to 1/2 irich in diameter, often 

 drying very hard; nutlets smooth, more 

 or less united. (Syn. A. platyphylla 

 (Gray) Kuntze.) 



Greenleaf manzanita is one of the 

 common manzanitas of the parks of the 

 Southwest and of the Sierra Nevada 

 Mountains of California, extending 

 north to Crater Lake National Park in 

 Oregon. It is one of the chief associ- 

 ates in ponderosa pine forests where it 

 favors dry open slopes or old burns 

 where the plants can obtain full sun- 

 light. In areas where it occurs it is fre- Fig. 112. Greenleaf manzanita 

 quently the dominant species, often (Arcioslaphvlos patula).
