RYDBERG: Rocky MOUNTAIN FLORA 423 
the type collection. The flowering specimen is identical with my 
A. Besseyi, but the fruiting specimen is not. The flowering speci- 
men has long linear-subulate calyx lobes, 4 mm. long, and linear- 
lanceolate, acute bracts, while in the fruiting specimen the calyx- 
lobes are almost triangular and about half as long and the bracts 
lance-oblong and obtuse. If the fruit of the type sheet is infected 
by uredo, there is no evidence of it in the duplicate here at the 
Botanical Garden. The trouble is that Aragallus Blankinshipii 
was described from flowering specimens of one species (A. Bessey?) 
and fruiting specimens of another. They are both well known to 
me. I intended to describe the second species in the Flora of 
Montana when in the meantime Professor Nelson’s article in Ery- 
thea appeared. I had no authentic specimens of his new species. 
As I knew of no species answering to Professor Nelson’s descrip- 
tion of A. Blankinshipii, never suspecting it to be a composite one, 
and knowing one agreeing fairly with his description of A. collinus 
except as to the color of the corolla, I referred the specimens of 
my supposed new species to this. The New York Botanical 
Garden has since received authentic specimens of both A. Blank- 
tnshipit and A. collinus and I have been able to correct my mis- 
take. The specimens referred to A. col/inus in my Flora of Mon- 
tana are specifically the same as the fruiting specimens of A. 
Blankinshipi. Mr. Gooding has also collected good fruiting 
specimens in Wyoming at Alcona, Natrona County, in 1901 (wo. 
147). These were determined as A. Blankinshipiz. 
This species is closely related to A. xanus, differing mostly in 
the erect stiff scape and more elongated spike. A. Besseyz, to- 
gether with A. argophyllus, forms a small group more related to 
A, Lamberti. 
I adopt the name A. Blankinshipii for this species, represented 
by the fruiting specimens of the original description for the following 
reasons: (1) Prof. Nelson has laid most stress on the structure of 
the pod, associating A. Blankinshipii with A. collinus, A. multi- 
ceps, A. Lagopus and A. nanus, to which this species is related ; 
(2) The characters of the fruit in the genus Avagad/us are more 
reliable then those of the flowers to show the actual relationship ; 
(3) The species represented by the flowering specimens has already 
received a name. The synonymy of the two species is as follows :
