TWO NEW FORMS OF HIERACIUM. 7 



in bud, distinguish tins plant from both typical H. hypochceroides 

 and the var. sax ) rum. In both the latter the phyllaries are porrect 

 in bud. The outer phyllaries of the present plant are also much 

 laxer in early bad, and the stem has more numerous white hairs 

 than in the type or in var. saxormn. The tint of the leaves is of a 

 lighter green than in the type, but agrees with that of the var. 

 saxurum. 



Plentiful on a range of limestone rocks near Merthyr Tydfil, 

 S. Breconshire, in company with the variety of H. pollijiarium P. J. 

 Hanb. described below. Fu'st noticed in 1894 ; gathered also in 

 subsequent years, and watched in cultivation. 



Though hitherto detected only at a single station, this plant 

 seems remarkable enough to deserve recognition and description 

 under a varietal name. I have Mr. Hanbury's consent to placing 

 it under H. hjpochmroides Gibs. 



HiERAciuM poLLiNARiuM F. J. Haub. var. PLA.TYPHYLLUM, nov. var. 

 Eadical leaves large, broadly ovate, often with triangular teeth near 

 the base; the teeth and the point of the leaf terminating in an 

 apiculus, thick and firm in texture when fresh, the under surface 

 with minute stellate down. Stem with 1-2 leaves, 9 in. -2ft. in 

 height, with long erect branches ; the branches, and especially the 

 very floccose peduncles, forming a very acute angle with the stem ; 

 phyllaries with strongly marked floccose margins, incurved at tip 

 in bud, as in H. miironim L. pt. ; ligules mostly but not always 

 stylose, styles dark olive-green. 



Differs from type H. polUnariuni F. J. Hanb. in the phyllaries 

 being more parallel-sided, with more black-based hairs and floccum ; 

 in the more floccose and less setose, longer, straighter peduncles, 

 which form a very acute angle with each other and with the stem ; 

 in the leaves not being retuse at tip, nor narrowed to the base, but 

 broad-based, with coarse, somewhat sagittate teeth. 



Mountain rocks, both of sandstone and Umestone ; frequent in 

 parts of South Wales, especially in Breconshire. 



Localities : — Herefordshire : Red Daren, Hatterel range. Black 

 Mountains. Monmouthshire : Taren-r'-Esgob, Llanthony Valley, 

 Black Mountains. Breconshire : frequent on the cliffs of the Black 

 Mountains, near the above stations in Herefordshire and Mon- 

 mouthshire. Frequent on the Brecon Beacon range ; Craig Gled- 

 siau and Craig Du (all the above stations on sandstone) ; Craig 

 Cille, near Crickhowel ; Dyffryn Crawnon ; Dan-y-graig and other 

 spots near Merthyr Tydfil (all these on limestone). Probably found 

 on the more western portions of this range in Carmarthenshire. 



First observed at the Herefordshire station in 1892, and at 

 several of its Breconshire stations in 1893. I have watched it 

 under cultivation since 1893, in the light loam of a South Hereford- 

 shire garden. Here it retains all its characteristics, but becomes 

 more robust, the crowns of the root increase in size, and throw up a 

 greater number of stems. It increases rapidly by seed in the garden. 

 The stylose ligules occur in about five out of six specimens, whether 

 in a cultivated or wild state, but this character does not appear to 

 be accompanied by any other variation in the plant.
