YELLOW RATTLE 



Rhinanthus Crista-galli. Figwort Family 



Stems: slender. Leaves: lanceolate, sessile, coarsely serrate-dentate, 

 acute, bracts ovate, incised-dentate, the teeth acuminate. Flowers: in 

 terminal, one-sided, leafy-bracted spikes, and solitary in the upper axils; 

 calyx much inflated, conspicuously veiny in fruit; corolla very irregu- 

 lar, two-lipped; the galea compressed, arched, minutely two-toothed 

 below the entire apex, the lower lip three-lobed, spreading. 



The name Yellow Rattle has been given to this plant on 

 account of the way in which the ripened seeds, which lie 

 loose in the capsules, rattle whenever the wind shakes them 

 to and fro. It is a firm erect plant, usually growing from 

 six to ten inches high, and chiefly conspicuous by reason of 

 its inflated green flower-cups and bright yellow blossoms, 

 the lips of which frequently are spotted with purple. 



GREATER BLADDERWORT 



Utricularia vulgaris var. americqna. Bladderwort Family 



Stems: immersed, scape stout, naked, three to four inches high, with a 

 few scales. Leaves: two to three pinnately many-parted, capillary, 

 bearing many bladders. Flowers: three to twenty in a raceme on short 

 pedicels, the sides of the lips reflexed, spur conical, slender, rather acute. 

 Fruit: capsule many seeded. 



The Greater Bladderwort is a very curious plant which 

 grows in shallow pools and ponds, and has yellow flowers 

 similar in structure to those of the Butterwort. The leaves, 

 usually much crowded on the floating branches, are divided 

 into thread-like segments bearing the numerous, velvety- 

 looking, little air bladders. In the autumn, buds termi- 

 nating the stems fall off, and are buried in the mud at the 

 bottom of pools until springtime, when they root, and the 

 new bladders, at first filled with water, soon fill with air, 

 and the plant, leaving the mud, rises to the surface of the
