TARAXACUM.

broader ligules dark olive beneath. Florets with their ligules 
twice the length of inv., their mouth dimidiately fringed or 
crowned with y. hairs. Scales of inv. closely imbricate in 
many rows, the lowest short ovate, the rest oblong or linear- 
lanceolate keeled mostly smooth but sometimes hirtose at 
least downwards more or less with w. bristly hairs, dark gr. 
with lurid dark livid or purpureo-violaceous tips like the bracts ; 
the keel often setose-fringed or bearded with stiff w. bristles, 
and always darkly echinato-serrate or crested upwards* at the 
tips. Recept. chaffy ; chaffs (as in H. glabra L.) long linear 
finely acuminate y. at the tips in fi., filmy w. and membranous 
below, shorter than the florets ; in fr. setaceo-acuminate with 
fine hair-like withered black tips equalling the pappus and de- 
ciduous with the ach. ; the latter fusiform muricately ribbed or 
echinato-scabrous chestnut-brown, all with slender long beaks 
longer than the ach. themselves, smooth upwards. Pappus 
dirty w. uniform stipitate in 2 rows, the outer row simple 
scabro-denticulate short, inner longer plumose. 
This resembles the common English Leontodon autumnal e 
L. (EB. t. 830), which differs however entirely in its truncate 
root, shorter less branched sometimes simple 1-fld. copiously 
scaly scapes or fl. -stems and naked chadless recept. : belonging 
indeed to the foregoing Tribe, Leontodontece. 
The var. /3 heterocarpa Moris, with the outer ach. beakless, 
from the Salinas of Cette (Gr. et Godr. 1. c.), has not occurred 
in Mad. 
Yillars 1. c. 64, well observes that the name juncea would 
be more obviously suitable to this pi. in allusion to its rush- 
like st. than radicata from its strong deep-running roots.
