This species is very close to T. strigosa Nutt. and it is doubtful whether it is possible 

 to separate the two. That species has been reported from New Mexico, but among our 

 material it is impossible to distinguish more than a single species. Our specimens 

 agree very well with those from farther north said to be T. strigosa.
