HEATH FAMILY 



301 



corolla broadly campanulate, 3-4 cm. long, rose-purple, the lobes broadly obovate, undulate; 

 stamens 10; filaments strongly declined, stout, about 2 cm. long; capsule oblong, ovoid, 15-20 

 mm. long, rusty-puberulent and glandular. 



Ravines and flats, Humid Transition Zone; western British Columbia, south through western Washington 

 and Oregon to the Santa Cruz Mountains, California. Type locality: "northwest coast of America." April-July. 



4. MENZIESIA Smith, PI. Ic. Ined. pi 56. 1791. 



Shrubs with erect or spreading branches. Leaves decidous, alternate, approximate on 

 the twigs, light green and thin, entire or obscurely toothed, gland-tipped, short-petioled. 

 Flowers in terminal clusters, appearing with the leaves, the pedicels nodding in anthesis, 

 erect in fruit. Calyx saucer-shaped, shallowly 4-lobed or entire. Corolla urceolate to 

 cylindraceous, the lobes 4, very small, rounded. Stamens 8, included; filaments subulate, 

 glabrous or sometimes pubescent at the base; anthers linear, unappendaged, opening by 

 terminal pores. Ovary 4-celled; style included. Capsule mostly ovoid, rather thick- 

 walled, septicidally 4-valved; seeds numerous, pointed or caudate. [Name in honor of 

 Archibald Menzies, surgeon and naturalist for the Vancouver Expedition.] 



A genus of 6 species, besides the following, M. glabella A. Gray is in the Rocky Mountains, M. pilosa 

 (Michx.) Pers. in the eastern United States, and 3 others are in Japan. Type species, Menziesia ferruginca 

 Smith. 



1. Menziesia ferruginea Smith. Pacific Menziesia. Fig. 3677. 



Menziesia ferruginea Smith, PI. Ic. Ined. pi. 56. 1791. 



Menziesia globiilaris Salisb. Parad. Lond. under pi. 44. 1806. 



An erect or straggling shrub, 1-2.5 m. high, with loosely shredded bark, the young twigs 

 finely pubescent and more or less glandular-pilose. Leaves oblong to elliptic or obovate, 3-6 cm. 

 long, obscurely crenate-serrate and ciliate on the margins, upper surface appressed-pubescent, 

 the lower surface usually so only on the veins ; pedicels glandular-pilose with more or less 

 matted ferruginous hairs ; calyx-lobes ciliate ; corolla 7-8 mm. long, cylindric-urceolate, yellow 

 tinged with red ; filaments glabrous ; ovary glabrous or sparsely pubescent ; capsule oblong- 

 ellipsoid, 6-7 mm. long; seeds caudate at both ends. 



Moist woods, in deep shade, coastal Canadian and Humid Transition Zones; southern Alaska, southward near 

 the coast to Humboldt County, California. May-July. 



The form in the Cascade Mountains of Washington and northern Oregon has the pubescence shorter, and 

 appears in that respect intermediate between M. ferruginea Smith and M. glabella A. Gray. 



5. KALMIOPSIS Rehder, Journ. Arnold Arb. 13:31. 1932. 



Low shrub with puberulent twigs, and evergreen foliage. Leaves alternate, entire, 

 glandular-dotted and gland-tipped. Flowers in terminal erect racemes, the pedicels very 

 slender, elongated, arising from the axils of small crowded membranaceous bracts. Calyx 

 5-parted, the lobes saccate at base. Corolla open-campanulate, 5-lobed, the lobes broadly 

 ovate, obtuse. Stamens 10, scarcely equaling the corolla; filaments slender, ciliate at base; 

 anthers oblong, dehiscent by terminal pores. Ovary 5-celled; style slender, erect, slightly 

 thickened below the capitate obscurely lobed stigma. Capsule subglobose, crustaceous,
