shining above, but with less asperity than //. diosmifolium, 

 about 6"' long, cottony white underneath. 



Flower heads hemispherical or slightly turbinate, rather larger 

 than those of 11. diosmifoliuin but less than those of //. decurre7i>i, 

 numerous in a terminal corymb. 



Involucre hemispherical, under 2 lines in diameter, the l^racts 

 obtuse, concave, all the outer ones scarious, straw-coloured, with 

 scarcely spreading tips, the inner circle yellow ^vith paler tips. 

 Florets about 25-30. Achenes hairy. Pappus-bristles serrulate, 

 not thickened upwards.

Analysis to show cognate species : — 



Involucral bracts with concave, erect or loose but 7iot spreading 

 obtuse tips, all or the inner ones white or pink. 



Leaves not decurrent Florets 20 //. diosmifoUum. 



Involucral bracts more or less scarious, obtuse, without any or 

 with scarcel}^ conspicuous white tips. 



Involucre ovoid-turhinate, narrow. 

 Florets about 15. Leaves 

 shortly decurrent ... //. hracteolatum. 



Involucre hemispherical. Florets 

 25 to 30, Leaves shortly 

 decurrent //. brevidecurreiis. 



Involucre hemispherical. Florets 

 35 to 40. Leaves very decur- 

 rent I/. tesselatu7n,si).nov. 



As will be seen in the analysis, it has greatest affinities with 

 //. hracteolatum, whilst it also appro^-ches fl. tesselatum in the 

 general resemblance of the involucre, but differs from it in the 

 shortly decurrent and more numerous leaves and smaller flower 

 heads. From H. adnatum it is distinguished by the shape of the 

 involucre and number of florets, and the pappus-bristles being not 

 thickened upwards, and its larger heads.
