GENTJS XXXIV.— R ELMINTHIA. Jnss. 



Anthodes many-flowered. Pericline oblong-ovoid, with 2 series 

 of phyllaries ; those of the inner series imbricated, those of the 

 outer few, broader, often foliaceous, nearly as long as the inner. 

 Clinanth naked. Achenes elliptical-ovoid, compressed, transversely 

 rugose, terminated by a slender beak about as long as the achene. 

 Pappus deciduous, of pure-wliite slender silky plumose hairs ; the 

 secondary hairs not interwoven. 



Scabrous almost prickly herbs, with dichotomously-branched 

 stems, the exterior ones usually red on the back. Elorets yellow. 



The Greek words whicli give a name to this genus of plants are tKfiLyQoc (elminthos), 

 of a worm, and drjKr] (theke), a case, from a fancied resemblance in the seeds.

Picris echioides, Linn. Svi. Eng. Bot. No. 972. 



Biennial. Stem erect, hirsute. Radical and lower leaves oblong- 

 oblanceolate or oblanceolate ; upper ones lanceolate, amplexicaul ; 

 all with white warts and prickle-like bristles and hairs. Anthodes 

 in an irregularly-dichotomous corymbose cyme. Pericline with the 

 outer phyllaries 3 to 5 in number, ovate-acuminate, cordate at the 

 base, bristly-spiny on the margins. Achenes transversely striated, 

 terminated by a long slender deciduous beak. 



In waste places, by roadsides, and in cultivated fields. E-ather 

 local, though pretty generally distributed over England. About 

 Berwick-on-Tweed and Tynetield, near Dunbar, in Scotland, but 

 perhaps introduced there. 



England, Scotland (?), Ireland. Biennial or annual. Late 

 Summer and Autumn. 



Badical leaves lying flat on the ground in a rosette, bearing 

 some resemblance to the young leaves of Echium vulgare, irre- 

 gularly sprinkled with unequal white tubercles, from which stiff* 

 bristles or weak prickles spring. Stem irregularly dichotomously 

 branched, rough with hooked hairs. Lower stem-leaves oblanceo- 

 late, and all except the lowest dilated and auricled at the base, the 

 uppermost of all tapering from the base to the apex ; all coarsely 

 dentate or repand-dentate, and ciliated with still' bristles. Outer 

 phyllaries very large, nearly concealing the inner ones, but not quite
