3. Lappula occidentalis (S. Wats.) Greene. Stickseed. Occasional on the east 

 slope at low altitudes, on flats or open slopes. Wash, to N. Mex., Mo., and Sask. — 

 Plants simple or branched, hairy, 15 to 60 cm. high; leaves spatulate, oblong, or 

 linear, 1 to 4 cm. long; corolla bright blue; fruit 3 mm. wide. 



The barbed prickles of this, as well as of the other species, enable the nutlets to 

 adhere readily to clothing. 



4. Lappula echinata Gilib. Dry slope near Many Glacier Hotel; along railroad at 

 Belton, frequent. Native of Eur. ; naturalized as a weed in N. Amer. — Stems 30 to 60, 

 cm. high, hairy, branched above; leaves mostly linear and sessile, 1 to 3 cm. long; 

 fruit 3 mm. broad. 



This species is not listed from the Rocky Mountains by Rydberg, but it is well 

 established at Belton. 



2. MERTENSIA Roth. 



1. Mertensia lanceolata (Pursh) DC. Bluebells. East entrance, on dry open 

 slopes. B. C. to Colo, and N. Dak. — Perennial; stems clustered, 15 to 40 cm. high, 

 glabrous; leaves alternate, entire, lanceolate or oblong, 3 to 10 cm. long, glabrous or 

 rough-hairy on the upper surface; flowers in small panicles; corolla blue, funnel- 

 shaped, with a thick tube. 



3. ERITRICHUM Schrad. 



1. Eritrichum howardi (A. Gray) Rydb. Alpine forget-me-not. Reported by 

 Jones from Brown Pass. Wash, to Mont, and Wyo. — Densely tufted perennial, 

 covered with appressed white hairs; leaves linear-oblanceolate, mostly basal; flowers

1. Myosotis alpestris Schmidt. Forget-me-not. Occasional above timber line, 

 in meadows or on rock slides. Alaska to Colo.; also in Eur. and Asia.- — Plants per- 

 ennial, 10 to 30 cm. high, hairy; leaves oblanceolate, 3 to 6 cm. long, flowers in 

 one-sided racemes, intense blue, 4 to 6 mm. wide; nutlets smooth. 



A beautiful plant, closely related to the cultivated forget-me-not. 



5. AMSINCEIA Lehm. 



1. Amsinckla barbata Greene. Fiddleneck. Dry open slopes at east entrance,

 covered with bristly yellowish hairs; leaves lanceolate to linear-oblong, 3 to 5 cm. 

 long, alternate; flowers in long one-sided racemes; corolla bright yellow, 5 mm. long. 



The hairs are so stiff and sharp that they penetrate the skin easily. 



6. LITHOSPERMUM L.

 altitudes, on prairie or open hillsides. B. C. to Nev., Colo., and Alta. {L. lanceolatum
