locally common. It is not quite the same as the eastern 

 plants the calyx being more deeply cleft above than below; it 

 may be named var. or subsp. hetheli. I consulted Mr. Oster- 

 hout about the matter, and he found the same character 

 in other specimens from various Colorado localities; near 

 Windsor, Weld Co., Livermore in Larimer Co., and Julesburg. 

 On the other hand, one from Wray, Yuma Co., near the Kansas 

 border, appears to agree with eastern specimens. 



Helianthns grosseserratiis of the Boulder list is H. coloradensis Ckll. 

 I now have in the garden H. parishii Gray, obtained by Mr. 

 Theodore Payne near Sevenoaks, in the San Bernardino 

 mountains, California. To my surprise, it is nearly identical 

 with coloradensis. The involucral bracts are shorter, and the 

 leaves tend' to be a little more distinctly dentate; but the 

 plants are essentially of the same type, and there would be no 

 serious objection to calling our plant H. parishii coloradensis * 

 The Calif ornian parishii grows taller, up to 15 feet. I thought 

 this statement might be an exaggeration, but it is confirmed by 

 Dr. H. M. Hall. The Calif ornian plant also presents a more 

 pubescent type, H. parishii f. oliveri (H. oliveri Gray), which 

 seems to be wholly lacking in our region. It is perhaps related 

 to a maritime environment. The H. coloradensis at Boulder 

 has an additional color-form (f. stdphurea, nov.), with pale or 

 sulphur-colored rays. It was found by Mr. Andrews. The 

 color is the or (gold) of Gravereaux's color chart, while the 

 typical form is his safran (saffron). 



Gymnolomia muUiflora (Nutt.) B. & H. Dr. S. F. Blake, 

 in his admirable recent revision of Vigiiiera, shows that this 

 plant is quite distinc tfrom the true Gymnolomia. It is the 

 type of Nuttall's Heliomeris, but Dr. Blake refers it to Viguiera, 



*Gaston Bonnier in his Flora of France, Switzerland and Belgium, and Hooker, 

 in his Flora of the British Islands, retain the binomials for all the subspecies or 

 races, a plan which has some advantages over that of trinomials, though it is too 

 easily a source of confusion. Presumably a citation of the aggreate species is not 

 to be taken as indicating necessarily the typical race, unless followed by "typica," 

 or "s. str." Some compromise is necessary for convenience, as any sj'stem of 

 nomenclature which expresses the actual facts in detail becomes too combersome for 

 general use. The objection to recognizing two grades of species, each with binomials, 

 is not so serious when there is a standard Flora in which all are described.
