Gen. Char. — Involucrum ( common calyx ) (fig. 1.) hemisphe- 
rical, closely imbricated ; scales narrow, loosely spreading at the 
points. Corolla compound, radiant ; florets of the disk (fig. 3.) nu- 
merous, perfect, tubular, their limb in 5 equal, upright or spread- 
ing segments ; florets of the ray (fig. 4.) numerous, crowded, strap- 
shaped, 3-toothed. Filaments 5, in the tubular florets only, thread- 
shaped, short. Anthers united into a cylindrical tube, with 5 sharp 
teeth at the summit, and 10 straight bristles at the base, (2 from 
each anther, (fig. 2.) equal in length to the filaments. Germen (see 
figs. 3 & 4.) in all the florets fertile, oblong. Style (see figs. 3 & 4.) 
thread-shaped, cloven. Stigmas spreading, oblong, rather blunt. 
Seed-vessel none, but the unaltered calyx. Seed (see fig. 5, a.) 
linear, rounded, hairy. Pappus (see figs. 5, b & c.) sessile, double ; 
outer one (b) short, cup-shaped, membranous, toothed ; inner (c.) 
long, rough. Receptacle slightly cellular ; cells fringed. Flowers 
yellow. 
Distinguished from other genera, with radiant flowers, in the 
same class and order, by the narrow imbricated scales of the invo- 
lucrum ; the 2 bristles at the base of the anthers ; and the double 
pappus. The last character will distinguish this from the genus 
Inula. 
Two species British.

Spec. Char. Stem woolly, panicled. Leaves oblong, wrinkled, 
downy, clasping the stem by tbeir heart-shaped or arrow-shaped
