_ calyx of linear-lanceolate divisions hirsute, glandular, and 
ciliate with crimped hairs; corolla purplish blue, hardly bila- 
biate, spreading lobes orbicular; two of the stamens inserted at 
the base, the other two half way up the limb, nearly on a line 
with the sterile filament which is moderately bearded down the 
side with hairs pointing downwards. In the descriptions of 
Penstemons no attention has been paid to the insertion of the 
filaments which may prove of use in determining species that 
seem closely related. This belongs to the Genuini and is nearest 
P. albidus of which it may prove to bea variety. It differs from 
PP. albidus in being less glandular, the shape and attachment of 
the leaves, the more interrupted inflorescence, the color and 
shape of the corolla, the denser beard of the sterile filament and 
‘in the explanate anthers which in P. albzdus are orbicular and 
in P. Moffatiz, oblong. It was collected at Grand Junction along 
the railroad to the coal beds, and I have named it in honor of 
David H. Moffat, ex-President of the D. & R. G. R. R., whose 
courtesy and kindness I wish to acknowledge. 
ABRONIA TURBINATA Watson. ‘This varies in the fruit, the 
wings in some specimens being well developed; in others, more 
or less aborted. 
ATRIPLEX CORRUGATA Watson. This was collected at 
Grand Junction, in May, 1892, with both moncecious and 
dicecious plants. The plants collected the previous season from 
which the description was made were all dicecious. 
‘ERIOGONUM BREVICAULE Nutt. This is the plant which 
Nuttall named 4. campanulatum, but which with £. micranthum 
Nutt. Dr. Gray reduced to £. brevicaule. He says that these 
three species are not permanently distinguishable even as 
varieties. The descriptions omit the most striking feature of the 
flower, the urn-shaped perianth, constricted at the throat and 
angled along the sides. All the flowers examined on the Grand 
Junction plants have perfect flowers. 
ERIOGONUM GLANDULOSUM Nutt. This has been but rarely 
collected, and the description isimperfect. My specimens agree 
with Nuttall’s description of Oxytheca glandulosa under which
