Raised from seeds sent by Dr. Wright from Texas, and quite 
hardy, flowering in the open air as late as November 1st, when 
our drawing wasmade. In foliage the species certainly more 
closely resembles G. inuloides, Bot. Reg. t. 248, than G. squar- 
rosa, figured in ‘ Botanical Magazine,’ tab. 1706, but it appears 
on comparison distinct from both, especially in the great size of 
the flowers (capitula) and in the deep orange-yellow of the broad 
ray, no less than in the great height of the plant, three to five 
feet in our garden. It must be confessed, however, that the 
Species of the genus are very variable and ill-defined.
