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 “‘calcdreo-glandulosis,’’ but merely 
viscid-pubescent as described by Dr. Gray. In the type they are 
covered by grains of sand, thatisall. It is without doubt a species 
of Gila 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. rigidula 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 pas 
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 Sudptical 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.
