base. Inflorescence sometimes only 7 cm., at others more than 20 em. 
long, 5-15 cm. broad. Bracts few, +2 mm. long. Capitula 1 em. long. 
Involucres 9 by 1-1°5 mm., their outer leaves 1-2 mm. long. Achenes

A remarkable plant, differing from the widely diffused ZL. levigata DC. 
in the tall habit, the narrow leaf on its very long stalk, and the narrower and 
longer flowering heads.
