imbricate. Stamens 4, 2-dynamous;' 2 smaller, often sterile or 

 rudimentary, sometimes 0. Germen inferior, unequal, sometimes 

 more or less gibbous or carinate; cells 1, 1-ovulate ; style slender, 

 sometimes incurved, capitate, globose or discoid-peltate at stigmatose 

 apex. Fruit dry, clothed with involucel, sometimes rather compressed, 

 crowned with calyx (or, rarely, bare at apex). Seed descending, 

 albuminous. — Perennial herbs, glabrous or pubescent ; leaves opposite 

 or verticillate; the lower often rosulate; pinnatifid or spinose-dentate * 

 or ciliate ; flowers^ axillary and terminal in compound glomerules and 

 forming verticillasters, bracteate ; each clothed with an unequally 

 spinose-dentate involucel. {Mid. and west. Asia.*) 



4 ? TriplostegiaWALL.'* — Flowerssubregular; receptacle enclosing 

 germen, and produced above to a narrow calyciform neck. Calyx 

 short cupular, 4, 5-dentate. Lobes of corolla limb 4, 5, subequal or 

 unequal, imbricate. Stamens 4, 5, inserted on corolla, unequal. 

 Germen inferior, 1 -celled ; ovule 1, descending ; style slender, capi- 

 tate at stigmatose apex. Fruit dry, crowned with calyx, enclosed by 

 involucel ; seed descending albuminous. — ^A slender pilose or glandu- 

 lose herb ; rhizome slender ; leaves opposite, inciso-pinnatifid ; the 

 lower sabrosulate, petiolate ; the upper sessile ; flowers ° in terminal, 

 2-chotomous compound ramose and slenderly stipitate cymes ; each 

 clothed with 4 exterior linear-lanceolate capitato-glandular ^ bracts 

 and an interior gamophyllous, 8-costate and above minutely dentate 

 involucel. {Himalaya.^) 



II ? BOOPIDEiE. 



5. Boopis J.— Flowers hermaphrodite or more rarely polygamous; 

 receptacle saclike angular, enclosing adnate germen. Calyx superior 

 short; lobes 4-6 (oftener 5), continuous with angles of receptacle,
