SOME ERIGERON SEGREGATES. 193 



gathered by O. B. Metcalfe, 15 Aug,, 1903, and distributed 

 under the name of T. grandis on my authority. That de- 

 termination was made quite too inconsiderately. While geo- 

 graphically the New Mexican plant is quite as far removed 

 from the habitat of the western species as from the eastern 

 one, the great dimensions of it seemed to connect it with T. 

 graiidis ; also the achenes were seen to have something like 

 the more elongated beak of those of T, grandis ; but, on care- 

 ful comparison it becomes clear that in the species last named 

 the long beak is in the main straight, being merely hooked at 

 the end, while here in the geographically intermediate plant 

 the whole style is coiled into something like a ring ; also the 

 body of the achene has markings between the main angles 

 which ally it with the two eastern species above described 

 as new. 



Specimens from a very different part of New Mexico, 

 namely of the Pecos River country, are in U. S. Herb., col- 

 lected in 1908, by Mr. Paul Standley, They are all imma- 

 ture and incomplete. I dare not assume that they are refer- 

 able to T. media ; for the foliage seems different, and smaller. 

 Neither do they furnish clear warrant for any opinion that 

 they represent another species. 



Some Erigeron Segregates. 



Nearly all the new propositions here following under the 

 above title are aptly to be denominated segregates because of 

 their having been listed in books under old names. Superficial 

 glances, and rough guesses as to identity, such as authors 

 often content themselves with, give example to herbarium 

 aids, and to those who collect and sell specimens ; thus is en- 

 gendered wild confusion of many species under one name in 

 the thick bundles of the larger public herbaria ; and perhaps 

 none are now worse off in that regard than those of so-called 

 Erig€ro7i, this notwithstanding that in recent years not a few 

 new segregates have been indicated by the few of us who
