GRIFFITHS—THE GRAMA GRASSES. 873 
Chondrosium foenum Torr. in Emory, Mil. Reconn. 154. pl. 12. 1848. The plate is 
sufficient to identify this. 
Chondrosium papillosum Torr. in Marcy, Expl. Red. Riv. 300. 1852. Based upon 
Atheropogon papillosus Engelm. 
Bouteloua foena Torr. Cat. Pl. Surv. W. 100th Merid. 18. 1874. Based upon Chon- 
drosium foenum Torr. 
Chondrosium drummondii Fourn. Mex. Pl. 2: 137.1881. The type number (Drum- 
mond 323) in the herbarium of the Muséum at Paris and in the herbarium of the St. 
Petersburg Botanical Garden belong to this species, but the prolongation of the rachis 
is rather short in the fragments before me from both the above depositories. A photo- 
graph of the type taken for me by A.5. Hitchcock in 1907 represents the typical form 
of the species. 
Bouteloua aschenborniana Griseb.; Fourn. Mex. Pl. 2: 137, 1881. A manuscript 
name mentioned as a synonym of Chondrosium aschenbornianum Nees. 
Bouteloua palmeri Vasey, Bull. Torrey Club 14: 9, 1887. A name only. Vasey 
observes that this species, which was distributed to some extent under this name, is a 
variety of B. hirsuta. 
Bouteloua hirsuta minor Vasey, U.S. Dept. Agr. Div. Bot. Bull. 12 1; pl. 39. f. 2. 
1890. See B. hirsuta major. The type of this variety appears to be a specimen col- 
lected in Texas, 1883, by 8. B. Buckley. 
Bouteloua hirsuta major Vasey, U. 8S. Dept. Agr. Div. Bot. Bull. 12!: pl. 39. f. 8. 
1891. The specimen in the National Herbarium locates Vasey’s work without doubt, 
although the label is not in Vasey’s writing. 
Bouteloua hirsuta palmeri Vasey; Beal, Grasses N. Amer. 2: 417. 1896. Vasey 
says that this has been distributed as B. palmeri, but he refers it to B. hirsuta. The 
specimen in the National Herbarium plainly marked by Vasey ‘‘Cultivated from seed 
collected by Palmer in Mexico, 1886,”’ fixes the type without any question. Watson ® 
also uses this name. 
Bouteloua bolanderi Vasey; Beal, Grasses N. Amer. 2: 417. 1896. Beal mentions 
this as a synonym under B. hirsuta variety palmeri. Itis said to have been cultivated 
from seed collected by Palmer in Mexico in 1886. I have not been able to find in the 
National Herbarium any specimen marked B. bolanderi. 
Bouteloua hirta Scribn. Contr. Nat. Herb. 2: 531, 1894, Based on Chondrosium 
hirtum H. B. K. 
Bouteloua hirta major Vasey, Contr. Nat. Herb. 2: 531. 1894. 
Bouteloua hirta minor Vasey, Contr. Nat. Herb. 2: 531. 1894.
