5. ANTHOPOGON Neck. 
Annual, biennial or rarely perennial herbs. Leaves opposite: blades entire, sessile. 
Flowers perfect, solitary at the end of the stem or its branches, the whorls mostly of 4 
parts each. Calyx relatively large: lobes unequal, keeled, the inner broader and markedly 
wider than the outer, scarious- or hyaline-margined. Corolla showy : tube campanulate- 
funnelform : lobes more or less spreading, erose or fimbriate, not accompanied by plaits in 
the sinuses. Stamens usually accompanied by a row of. glands at the base of the filaments. 
Ovary l-celled. Ovules numerous. Capsule stipitate. FRINGED GENTIAN. 
1. Anthopogon crinitum (Froel.) Raf. Annual. Stems 2-5 dm. tall, commonly 
branched : leaf-blades ovate to lancevlate, mainly 2-5 cm. long, sessile and partly clasping : 
calyx 2.5-3 cm. long, glabrous, the outer lobes lanceolate, acuminate, the inner much 
broader, scarious-margined : corolla deep sky-blue, 4-5 cm. long; lobes spreading, copi- 
ously fimbriate beyond the middle: capsule about 3 em. long. [Gentiana crinita Froel.

6. GENTIANELLA Moench. 
Annual, biennial or perennial herbs. Leaves opposite : blades entire, mainly sessile. 
Flowers perfect, solitary or in open or contracted cymes, the whorls of 4 parts each or 
sometimes of 5 parts. Calyx relatively small: lobes imbricated, essentially equal, or the 
outer broader than the inner. Corolla funnelform or salverform : lobes entire or sparingly 
toothed, not accompanied by plaits in the sinuses, but often filamentose at the base. 
Ovary l-celled. Ovules numerous. Capsule mainly sessile. 
. Gentianella quinquefólia (L.) Small. Annual or biennial. Stems 1-11 dm.
