lo H. incana and those spécimens belong to H. hirsuta. The forms incladed 

 in this species are collectively distinguished from the forms included in 

 H. incana by the larger number of ilowers (7-10) to eacli glomerule, 

 which are sessiie and not pedicellate and in which each segment of the 

 calyx is terminated by a setule. H. incana is further stated to be truly 

 perennial. Linnœus, in the second part of Mantissa Plantarum, says of 

 ""this species, « simillima Heriiiarise glabrœ, sed caules rigidiores. >>
