240 ROBINSON. 



This is the phint which has in recent years been passing as E. 

 Muclleri Sch. Bip., the identity of which is discussed below. 



The plant here described as E. choriccphahnn, although for many 

 years well represented in herbaria, appears never to have been char- 

 acterized. Dr. Gray evidently glimpsed the plant as a separable 

 entity and gave it a manuscript name as a variety oi E. grandidcntatum 

 DC, but he may have lost confidence in it or altered his conception of 

 E. grandidcntatum (which has subsequently proved a synonym of the 

 older E. pazcuarense HBK.), for he never published a description of 

 this variety. 



Dr. Gray's varietal name, Jaxiflorum, notwithstanding its morpho- 

 logical inaccuracy, as well as its lack of characterization and conse- 

 quently negligible nature, would have been here taken up in the 

 specific ranlv, except for the circumstance that it would have necessi- 

 tated making Pringle's no. 747 the type of the species, since it would 

 have been the type of the name-bringing synonym. It happens, 

 however, that this particular number, while pretty clearly conspecific 

 with the others here referred to the new species, is by no means central 

 or typical among them, being in fact a little firmer in general texture 

 and having slightly more rigid pedicels. It therefore seems ill-fitted 

 to function as the type of the group (otherwise pretty uniform) in 

 which it seems a trifle exceptional.
