Dr. Brand excluded Gilia caespitosa A. Gray not only from the 

 genus but also from the family. He makes the following remark: 

 "Species foliis calcareo-glandulosis ab omnibus Polemoniaceis 

 valde abhorret; fortasse Saxifragaceis attributa est." 



The leaves are by no means "calcareo-glandulosis," but merely 

 viscid-pubescent as described by Dr. Gray. In the type they are 

 covered by grains of sand, that is all. It is without doubt a species 

 of Gilia and probably, as Dr. Gray suggested, related to G. subnuda, 

 but as the corolla was unknown the placing in the genus was 

 uncertain. One thing is certain, it should not be placed next to 

 G. rigidida as it is in the Synoptical Flora. The duplicate of the 

 type in the National Herbarium bears a single withered and partly 

 torn corolla; this is trumpet-shaped and about I cm. long; the 

 real structure is not possible to make out, but the plant is prob- 

 ably related to G. subnuda. 



Dr. Brand gives Micranthes diffusa as a synonym under Gilia 

 gracilis subspecies humulis var. micrantha, while he cites Heller 

 3098 (its type) under G. gracilis subsp. eu-gracilis var. eritrichoides, 

 which shows carelessness in identifying the different forms de- 

 scribed. In the Columbia University herbarium there is' a dupli- 

 cate of Douglas's collection, which shows that Brand's var. 

 eritrichoides is the typical form of Microsteris gracilis (Dougl.) 

 Greene. 



Dr. Gray in his Synoptical Flora* segregated out Gilia aristella 

 from material he had previously included in Collomia linearis 

 subulata. The latter he regarded as the same as Collomia tinctoria 

 Kellogg. Notwithstanding this judgment of Dr. Gray, which 

 always will weigh considerably, Dr. Brand made Collomia aristella 

 (A. Gray) Rydb. a synonym of C. tinctoria Kellogg, while he named 

 C. tinctoria subulata (A. Gray) Brand from Gray's variety C.
