Gilia floccosa Gray var. filifolia (Nutt), n. comb— G. 

 filifolia Nutt. Jour. Acad. Phil. 1:156. 1848; Navarettia filifolia 

 Brand, op. cit. 167; G. virgata Steud. var. filifolia Milliken, Rev. 

 Col. Polem. 39. 1904. — Although G. virgata and G. floccosa admit- 

 tedly merge, they are distinct enough in their typical development 

 to warrant their separation, which is conducive to clearness and 

 simplicity when one considers their respective variations. G. 

 Wilcoxii A. Nels. Bot. Gaz. 34:27. 1902 is G. floccosa. The fore- 

 going variety is distinguished by its shorter, more salverform 

 corolla, the narrow lobes much shorter than the tube. 



POLEMONIELLA. — Brand in his recent monograph of the 

 Polemoniaceae reduces Polemoniella Heller, Muhl. 1:57. 1904. 

 This genus is undoubtedly as strong as the Gilia segregates he 

 accepts. It not only has the technical characters indicated and 

 the corolla shorter than the calyx, but these combine to give the 

 plants an aspect that suggests Nemophila or Ellisia. In fact, Brand 

 marked a specimen (in this herbarium) of Polemoniella, N. brevi- 

 flora. Besides P. micrantha (Benth.) Heller, the genus contains 

 the following species, both South American. 



Polemoniella Gayanum (Wedd.), n. comb. — Gilia Gayanum 

 Wedd. Chlor. And. 2:82. 1859; P. Gayanum (Wedd.) Brand, 

 Pflanzenreich 4:46. 1907. 



Polemoniella antarcticum (Griseb.), n. comb. — P. antarc- 

 ticum Griseb. in Goett. Abh. 6:131. 1854. 



Heliotropium curassavicum L. var. xerophilum (Ckll), n. 

 comb. H. xeropkilum Ckll. Bot. Gaz. 33-'379- 1902; H. spa- 

 thulatum Rydb. Bull. Torr. Bot. Club 30:262. 1903 . — Cockerell 

 has called attention (Proc. Biol. Soc. Wash. 26:204. 1913) to the 

 fact that his name for this large-flowered inland form antedates 

 Rydberg's. He is wrong, however, in believing that it is the 

 only form found in New Mexico and Chihuahua, there being 

 collections from these localities that represent the species per- 

 fectly. Especially in California and the Southwest interme- 

 diates occur which prove the fallacy of trying to maintain the 

 inland plant as a species. H. oculatum Heller, Muhl. 1:58. 

 1904, judging from the author's specimens, is one of these inter- 

 mediate states. In its best development, however, the variety is
