That plant is much larger than the genuine species, has the 

 leaves ending in a fine thread, covered all over with a coarse 

 shagginess vv^hich breaks up into a kind of chaffy fringe at the 

 edges ; the bracts are protected in the same manner, and with 

 the flowers form a hemispherical head quite overtopped by the 

 slender points of the leaves. To this the name of T. Gardneri 

 may be applied, with the following diagnosis. 



T. Gardneri ; uudique ramentaceo-lepidota, foliis lanceolatis in acumen fili- 

 forme productis exterioribus patentibus interioribus spica longioribus, 

 scapi vaginis filiformi-acuminatis erectis, spica simplici hemisphsericu, 

 bracteis oblongis superioribus obtusis calycibusque mollibus tequilongis.
