Calamagrostis scopulorum Jones.* 
Last spring, when Mr. Jones was engaged in naming his col- 
lection of Utah plants at the National Herbarium, his specimens 
of Calamagrostis were submitted to me for determination, as I am 
engaged in revising the North American species of that genus. I 
mentioned to Mr. Jones that the species in question was doubtless 
an undescribed one, and requested that the specimens be left with 
me for further study. Mr. Jones told me that he would have to 
take the specimens away then to catalogue them, but gave me the 
impression that I should have an opportunity to examine them 
later on. Since then I have not seen them, and specimens of 
this, as well as of Mr. Jones’ two other new species of grasses, ap- 
pear to be missing from the set deposited in the National Herbar- 
ium. I think it well to call attention to this as an instance of a 
Species of discourtesy (to use no harsher word) too often suffered 
by students of special groups. 
Calamagrostis scopulorum is a pédlectie distinct species of 
rather perplexing relationship. It is mo¢ closely allied to C. sy/- 
vatica, being distinguished from all species of that group by its 
slender, straight awn not exceeding the flowering-glume. In its 
spikelets it resembles C. A/eutica, but is widely different in its 
vegetative organs, habit and appearance. At first glance it ap- 
pears very close to C. Cusickit, but is readily distinguished by the 
shorter and more delicate awn and longer callus-hairs. The same 
species was collected by Mr. Jones at Alta, Utah, in 1879 (no. 
1145). Some expressions used in the description are rather pecu- 
liar, such as “ spikelets appressed,” “ outer ” and “inner rays ” of the 
panicle, lower empty glume and palet “simply acute,” etc. It is 
not usual, in describing grasses, to mention the characters of the 
palet before describing the flowering- glume. 
In passing, it may be worth while to mention that, as Lamarck 
published a Poa festucoides, that name is not available for Mr. 
Jones’ species, for botanists of every school have practically agreed 
that, from now on, at any rate, the law of homonyms shall be ob- 
served, even if it be not made retroactive. An Elymus with the
