GENTIAN FAMILY. Gentianaceas. 



A familiar species of the Middle and 

 Gentian'* Western States closely resembling the 



Gentiana Bottle Gentian. The pale blue-violet, or 



Saponarin light lilac-blue flower is only parti}- open, 

 Pale blue- the five lobes are blunt, erect, slightly cut 



August- at the tip ' and the flower - cu P is clut) - 



October shaped, the anthers within cohering in 



a ring. The light green leaves are com- 

 monly ovate lance-shaped, three-ribbed, and pointed 

 at either end, the edges rough. The flowers form a 

 terminal cluster; a few grow from the leaf -angles. They 

 are frequented by honeybees and bumblebees ; Bom- 

 bus americanoni~n is a common visitor. Both this 

 Gentian and the preceding- one ripen their pollen before 

 the stigma is receptive and cross-fertilization is there- 

 fore inevitable. The smooth and slender stem is 12-27 

 inches high. The juice of the plant is soapy. In wet 

 woodlands from N. Y., west to Minn., and south. 



A perennial. In the east this is the 

 Closed "oentian commonest of all Gentians; it is remark- 

 Gentiana able for its tight -closed bottle -shaped 



Andrewsii corolla,which is contracted by plaits white- 



stri P ed ' white at the base and an intense 

 violet-blue at the apex ; sometimes the 

 blue approaches ultramarine. The medium 

 (sometimes rusty) green leaves are smooth, ovate lance- 

 shaped, pointed at the tip, and generally narrowed at 

 the base. The flowers are mostly crowded in a terminal 

 cluster, but some grow from the leaf-bases; all are set 

 close to the leaves, which are conspicuously arranged in 

 pairs. Bumblebees not infrequently force an entrance 

 into the corolla, and self-fertilization is sometimes ques- 

 tionable. The smooth, round stem 1-2 feet high. Rich 

 woodland borders, Me. to S. Dak., south to Ga. and Mo. 

 A much less common Gentian frequent- 

 linearis * n S mountain bogs. It is a smooth, slen- 



Light blue- der-stemmed perennial, with light green 

 violet linear or lance-linear leaves with three 



ribs, acute at either end. The pale blue- 

 violet flower-cup is contracted to a funnel- 

 form with rather scallop-shaped lobes ; the light green,
