Gen. Char. Involucrum ( common caly J (see fig. 1.) double, 
outermost (fig. 1, a.) of a few short, awl-shaped, deciduous scales, 
at length ribbed and furrowed (fig. 3.); inner (fig. 1, b.) oval, 
simple, furrowed, permanent, of several, strap-shaped, converging 
scales. Corolla (fig. 2.) compound, of numerous, imbricated, uni- 
form, perfect, strap-shaped, blunt, 5-toothed florets (see fig. 4). 
Filaments (see fig. 5.) 5, hair-like, very short. Anthers (see fig. 5.) 
in a cylindrical tube. Germen (see fig. 5.) inversely egg-oblong. 
Style (see fig. 5.) thread-shaped, slightly prominent. Siigmas 2, 
spreading Seed-vessel none, except the converging, hardened, 
inner calyx. Seed (see fig. 6.) transversely wrinkled, with a long 
awl-shaped beak. Pappus (see fig. 6.) hair- like, copious, stipitate. 
Receptacle (see figs. 7 & 8.) naked, or very slightly hispid, flattish. 
The involucrum with awl-shaped scales at the base; the trans- 
versely wrinkled seed, with a long awl-shaped beak; the hairy, 
stipitate pappus ; and the naked or very slightly hispid, flattish 
receptacle; will distinguish this from other genera, with uniform 
strap-shaped florets, in the same class and order. 
It differs from Crepis, t. 366, in the pappus being stipitate, not 
sessile. 
One species British. 
BORKHA'USIA FCETIDA. Fetid Borkhausia. Stinking Hawk’s- 
beard. Stinking Castor-weed. Colton Groundsel. 
Spec. Char. Stem hairy. Leaves hairy, sessile, pinnatifid, 
with reversed teeth ; upper ones spear-shaped, cut at the base. 
Involucrum downy.
