BORAGE FAMILY 557 



15. ERITRICHIUM Schrad. in Gaud. Fl. Helv. 2: 57. 1828. 



Low depressed cushion-like perennials, with the short stems densely clothed with small 

 often imbricate leaves. Flowers few in a raceme-like cluster terminating the slender flower- 

 ing stems. Calyx-lobes ascending, linear. Corolla blue, funnelform, with short tube. 

 Nutlets obliquely attached to the conical gynobase, smooth, the apex obliquely truncate, 

 with a distinct, entire or toothed margin. [Name Greek, meaning wool and small hair, 

 the original species being woolly-pubescent.] 



A genus of about 30 species, inhabiting the boreal and temperate regions; 4 or 5 are North American. Type 

 species, Eritrichium nanum Schrad.

 Oreocarya pulvinata A. Nels. Bot. Gaz. 40: 63. 1905. 



Densely cespitose, forming cushion-like mats. Leaves closely overlapping, oblanceolate, 4-8 

 mm. long, LS-2 mm. broad, acute or obtuse, pilose, especially on the margins and tips, with 

 long white hairs ; flowering stems 2-6 cm. long, with scattered narrowly linear leaves ; flowers 

 in a short terminal raceme-like cluster; calyx-lobes linear, 3 mm. long; corolla-tube equaling 

 the calxy-lobes, limb bright blue, 4-6 mm. broad, crests in the throat puberulent ; nutlets smooth, 

 2 mm. long. 



Rocky ridges, Boreal Zones; Wallowa Mountains, Oregon, east to Idaho, Montana, Wyoming and Colorado. 

 Type locality: Spanish Basin, Montana. July-Aug. 



Eritrichium Howardii (A. Gray) Rydb. Mem. N.Y. Bot. Gard. 1 : 327. 1900. {Cynoglossum Howardii 

 A. Gray, Syn. Fl. N. Amer. ed. 2. 2^: 188. 1886.) Similar to E. elongatum; leaves with dense closely appressed 

 pubescence; dorsal surface of nutlet papillose and hispid; corolla-limb 7-9 mm. broad. Montana and northern 

 Wyoming, mostly on the eastern side of the Rocky Mountains. Reported from the Cascades, Washington, on the 

 basis of a specimen said to have been collected by Tweedy, but this is possibly a slip in labeling, as Tweedy also 

 collected the species in Montana. Type locality: "Rocky Mountains in Montana." 



16. GREENEOCHARIS Guerke & Harms in Engler & Prantl, Nat. Pflanzenf. 



Regist. 460. 1899. 



Low, densely branched annuals with hispid or canescent herbage, containing a purple 

 dye that leaves a stained impression of the plant on pressing paper. Flowers in leafy- 

 bracted spikes terminating the numerous branchlets. Calyx 5-cleft to the middle, the tube 

 scarious and circumscissile near the middle, the upper part bearing the lobes falling away, 

 the lower cupulate, densely hispid, and persistent around the ovoid nutlets. [Named in 

 honor of E. L. Greene, noted American botanist, and the Greek word meaning grace or 

 beauty.] 



A monotypic genus of western North America.

 Greeneocharis circumscissa Rydb. Bull. Torrey Club 36: 677. 1909. 



Stems few to many from the base, strigose, more or less branched above, often forming a 

 dense hemispheric mass 2-10 cm. high, the outer ones often decumbent. Leaves 3-15 mm. long, 

 1-2 mm. broad, the lower narrowly oblanceolate, the upper linear, obtuse, strigose or short- 

 hispid; flowers in the axils of foliaceous bracts in short rather indefinite raceme-like clusters; 

 corolla minute, limb 1-2.5 mm. broad; fruiting calyx 2.5-4 mm. long, the tube nearly as long 

 as the lobes, at length circumscissile just below the sinuses, basal part persistent, cupulate, 

 appressed-hispid ; mature calyx-lobes narrowly linear-lanceolate, firm, more or less hispid, 

 midrib slender; pedicels about 0.5 mm. long; nutlets 4, all similar or one slightly longer, tri- 

 angular-ovoid to oblong-lanceolate, about 1.5 mm. long, smooth or obscurely muriculate; gyno- 

 base about two-thirds height of nutlets, pyramidal-oblong; style equaling or slightly exceeding 

 nutlets. 



Sandy or gravelly soils, Sonoran and Arid Transition Zones; eastern Washington south through eastern 

 Oregon and California, east of the Sierra Nevada, to the mountain ranges of southern California and northern 

 Lower California, east to southern Idaho, Utah and Arizona. Type locality: Snake Fort, Snake River, Idaho. 

 April-Aug.

 from the typical species by the spreading hispid pubescence of the stems. Sierra Nevada, California, on the 

 western slopes in Fresno, Tulare and Kern Counties, and on the eastern slopes in the Lake Tahoe and Mount 

 Whitney regions; also in western Nevada in the Carson Valley region. Type locality: Mount Whitney trail,
