Professor Greene describes this as " a subalpine species, of the 

 mountains back of Santa F6, New Mexico ; this description drawn 

 from Fendler's no. 43 as found in the U. S. Herbarium." 



As has been noted above, a lar<;e part of Fendler's no. 43 is

I). Nco-Mcxicana is the plant referred to under D. Hdlcriana, 

 where Professor Greene says that "Mr. Heller did not find the 

 subalpine Fendlerian type on which Gray founded his D. aurca var. 

 stylosar Professor Greene was not present with me in New Mexico 

 when I made the collection referred to, neither have I ever told 

 him that I did not collect this particular plant ; hence he must 

 have merely inferred that I did not, simply because he never saw 



it under one of my labels. 



Neither am I able to see how he could safely accus« a man of 

 " bombast" when he acknowledged in the citation of the type of

Furthermore, I fail to find any support for the assertion that this 

 is a subalpine plant.anymore than is D. Hdlcriana. In the "Plantac 

 Fendlerianae," the locality is given as " shady declivities, along 

 Santa F6 Creek, at the foot of mountains, etc. ; May to July." 

 Fendler's field note reads : " 8th May-28th July, 1847. Santa Fe 

 Creek, shady steep declivities and foot of mountains. More rarely 

 in the' creek bottom and low banks of the creek." Indeed, if a 

 low, stunted growth alone is to be taken as subalpine, such subal- 

 pine plants can be produced at sea level within the tropics. 



Fendler not only collected D. Hdlcriana and D. Neo-Mexicana, 

 two very distinct forms, but also a third less differentiated one, all 

 included under his no. 43- This third form is present on the type 

 sheet of D. aurca var stylosa, but it is there represented by only one 

 small plant. It is well represented, however, in the George Engel- 

 ^nnn H.rK.'innm at the Missouri Botanical Garden. Through the
