5S BRITISH HIERACIA. 



Amongst the numerous roots whicli I have at different times 

 collected among the Clova mountains for H. ctesium, are several 

 of a plant that assumes under cultivation an appearance so con- 

 spicuously diverse from both the above, that I feel no doubt of its 

 distinctness ; and yet from insufficient acquaintance with the wild 

 form, I object at present to call it a species, but wish to direct 

 attention to it. For the present it may be described by the follow- 

 ing character and provisional name. 



H. OBTUSIFOLIIJM. YellovAsh green. Stem erect with one 

 leaf, corymbose. Original root-leaves ovate or broadly ellip- 

 tical, roimded at both extremities, nearly or quite entire, soft, 

 with short hairs. Petioles densely villous. Peduncles 

 spreading. Involucres ventricose^ ultimately truncate at 

 the base. Phyllaries acuminate. Florets shortly pilose at 

 the tips. Styles rather livid. 



In size this plant is intermediate between K. casium and H. cerin- 

 fhoides. It has a rather large shortly-stalked stem-leaf, lanceolate 

 or ovate-lanceolate more or less dentate inner root- leaves, and pale 

 creamy yellow jtorets. 



Wlen cultivated it is strongly marked by having the original 

 root-leaves (the wiuter rosette) pale yellowish green, soft, entire and 

 rounded at loth extremities, with short very shaggy petioles. It is 

 corymbose with numerous heads: outer branches and peduncles 

 exceeding the primary head : florets always pale (creamy) yellow.
