Gen. Char. Involncrum { common calyx ) (fig. 1.) double; 
inner of many compact, upright, equal scales ; outer of several lax, 
small, strap-shaped ones. Corolla compound, imbricated, uniform ; 
florets (fig. 3.) numerous, perfect, uniform, strap-sbaped, abrupt, 
with 5 teeth. Filaments (see fig. 2.) 5, hair-like, very short. 
Anthers (see fig. 2.) united into a cylindrical tube. Germen (see 
figs. 2 & 3.) nearly oval. Style (see fig. 2.) thread-shaped, the 
length of the stamens. Stigmas 2, reflexed. Seed-vessel none, 
except the permanent involucrum, which at length becomes reflexed 
(see fig. 6). Seed (see figs. 4 & 5.) transversely triated. Pappus 
(see fig. 5.) sessile, slightly feathery. Receptacle (see fig. 6.) naked, 
dotted. 
The double involucrum , innermost of many compact, upright, 
equal scales, outer of several lax, small, strap-shaped ones; the 
feathery, sessile pappus ; the transversely wrinkled seed ; and the 
naked receptacle ; will distinguish this genus from others in the 
same class and order. 
It differs from the genus Helminthia (t. 270.) in the pappus 
being sessile, not stipitate. 
One species British. •
