One of the conspicuous plants of alpine meadows, but seldom occurring in great 

 abundance. 



2. Delphinium bicolor Nutt. East entrance, on prairie, Umbach. Waslj. to Utah 

 and Sask. — Stems stout, 20 to 40 cm. high, hairy, at least above; leaves 2 to 4 cm. wide, 

 finely hairy or nearly glabrous; flowers deep blue, 1.5 cm. long; petals yellowish or 

 whitish; pods hairy or glabrous. 



4. AQUILEGIA L. Columbine. 



Perennials with thick roots; stems often branched, bearing 1 or numerous flowers; 

 leaves with numerous lobed leaflets; sepals 5, petal-like; petals 5, each with a long 

 spur at the base; stamens numerous; fruit of 5 pods. — Red columbine has been 

 reported from the region, but probably does not occur here. 



Flowers yellow; stems several-flowered 1. A. flavescens. 



Flowers blue; stems usually 1-flowered 2. A. jonesii. 



1. Aqullegia fl.avescens S. Wats. Yellow columbine. Common above and near 

 timber liae, in meadows, or on rocky slopes or rock slides; occasionally found at middle 

 elevations in woods. B. C. to Oreg., Wyo., and Alta. — Stems 20 to 60 cm. high, 

 usually in clumps; leaflets 1 to 4 cm. long, 3-lobed; sepals usually sulphur-yellow, but 

 sometimes very pale or occasionally salmon-pink; petals pale yellow, 5 to 8 mm. long; 

 spurs 1 to 1.5 cm. long; pods about 2 cm. long. 



A very handsome plant. The flowers vary greatly in size, and there are numerous 

 color forms. 



2. Aqullegia jonesii Parry. Blue columbine. Frequent on the highest rock 

 slides and on exposed rocky alpine slopes. Alta. to Wyo. — Plants 5 to 10 cm. high, 

 finely pubescent; leaves basal, 1 to 5 cm. wide, the leaflets glaucous, small and crowded ; 

 flower erect, the sepals 1.5 cm. long; spurs 8 to 10 mm. long; pods 1.5 to 2 cm. long. 



A showy plant whose flowers last only a short time. 



2a. Aqullegia jonesii elatior Standi., subsp. nov. Similar in general appearance to 

 A. jonesii, but the stems taller, 10 to 20 cm. high, usually 1-flowered but occa- 

 sionally 2-flowered, naked or often leafy-bracted; leaves 7 to 12 cm. high, the 

 leaflets somewhat larger than in the species, not crowded; flowers like those of 

 the species, the petals often white. 



Type in the U. S. National Herbarium, no. 1025123, collected on a rock slide above 

 Cracker Lake, Glacier National Park, Montana, altitude 1,920 meters, July 15, 1919, 

 by P. C. Standley (no. 15765). Also collected on rock slide above Iceberg Lake. 

 July 26, 1919 (no. 16407). 



This grows with typical A. jonesii, and at first glance it appears quite distinct. 

 While in the field it was presumed that two species of blue columbine were repre- 

 sented in Glacier Park, but close examination of the specimens secured does not 

 reveal any constant differences between the two forms. A. jonesii elatior is a larger, 

 greener, less pubescent plant than A. jonesii, and has larger leaves whose leaflets are 

 not crowded as in that species. It seems best to regard it as only a form of A. jonesii, 

 a view confirmed by Mr. Edwin B. Payson, who has examined the material. 



5. TEOLLIUS L. 



1. TroUius albiflorus (A. Gray) Rydb. Globeflower. Common above and near 

 timber line, in wet meadows; often about snow banks. B. C. and Wash, to Color 

 and Alta. — Glabrous perennial, 20 to 50 cm. high, with rootstocks; stems leafy, 1 or 

 few-flowered; leaves parted and lobed, 4 to 8 cm. long; sepals 5 to 7, white; petal, 

 linear, 3 to 5 mm. long; fruit of 10 to 20 pods about 1 cm. long. 



One of the characteristic plants of alpine meadows, springing up quickly after 

 snow leaves the ground, the stems sometimes even pushing up through thin snow. 

 The flowers are conspicuous, but they are of a dirty white color and not particularly 

 attractive.
