Gen. Char. Involucrum (common calyx) (fig. 1.) angular, 
imbricated ; scales dilated at the base. Corolla compound, of nu- 
merous, imbricated, uniform, perfect, strap-shaped, blunt, 5-toothed 
florets (fig. 2). Filaments (see fig. 3.) 5, hair-like, very short. 
Anthers (see fig. 3.) united into a cylindrical tube. Germen (see 
fig. 2.) oblong. Style (see figs. 2 & 3.) thread-shaped, prominent. 
Stigmas 2, recurved. Seed-vessel none, except the converging, 
finally spreading involucrum. Seeds (see figs. 4 & 5.) oblong, 
striated; tapering into a beak ; those next within the involucrum 
crowned with a row of short, flat, toothed scales only (see fig. 4.) ; 
the rest with a sessile, feathery pappus (see fig. 5). Receptacle 
(see fig. 7.) naked, dotted. 
The imbricated involucrum ; the. naked receptacle ; the seeds of 
the florets of the disk crowned with sessile, feathery, unequal 
pappus ; and those of the ray with a short scaly cup only ; will dis- 
tinguish this from other genera in the same class and order.
