CONTRIBUTIONS TO WESTERN BOTANY. 693 



BiGELOViA SQUARROSA (H. & A.) Aflopappiis squar- 

 rosus H. & A. Bot. Beech. 146. This seems to me much 

 better placed in Bigelovia and is close to B . Menziesii. 



BiGELOviA MACRONEMA (Gray). 



A^lo^arpfus macronenia Gray, P. A. A. 16, 80. 



Macronema discoidea Nutt., Tr. Phil. Soc. n. s. 7, 322. 



No. 594or. August 28, 1894, head of Bullion Creek, 

 near Marysvale, Utah, in gravel at 11,500° alt. 



No. 5895. August 24, 1894, Falls of BulHon Creek, 

 near Marysvale, Utah, 9500° alt., in gravel. 



It has always seemed to me that this species is a better 

 Bigelovia than Aflo^afpus; in fact it is so close to B. 

 Bolanderi that it is very difficult to separate the two spe- 

 cies. ^ I leave it for other botanists to determine whether 

 the other species in the section Macronenia of A^lopap- 

 ^us of Gray shall be transferred to Bigelovia. In my 

 judgment, however, the dividing line is better left here. 

 In discussing the species of Macronema, E. L. Greene 

 curiously enough says that this group is most nearly al- 

 lied to Chryso^sis. He fails to see that 3/acronenia passes 

 directly into Bigelovia and that it is well nigh impossible 

 to separate specifically Bigelovia Bolanderi and A^loj)ap- 

 pus macronema, while there is a direct transition to true 

 Bigelovia through these species and B . Parryi, Nevaden- 

 sis, Howardi, etc. I caunot follow Mr. Greene in his 

 work on Bigelovia, A^lopappiis, and allied genera. 



Bigelovia leiosperma var. abbreviata. 



No. 6105. October 7, 1894, mouth of Clear Creek 

 Canon, Utah, 6000° alt., in clay. 



^ Ver}^ minutely pubescent throughout, not at all floc- 

 cose ; leaves mostly very much reduced and almost scale- 

 like, linear, 4" or less long, apiculate, barely flattened; 

 scales nearly all linear and with only a trace of green at 

 the tip, not at all keeled; flowers mostly double the rather
