Mr. N. L. Britton presented " Notes on the Autumn Flora of 

 Southern Wyoming and Eastern Colorado," illustrated by specimens 

 of the more common and striking plants noticed in that country in 

 September and October. The most prominent feature observed by 

 Mr. Britton in the Flora of Wyoming along the line of the U. P. R. 

 R. was the very general absence of trees, the only species seen being 

 Ftnus flexilis, James, and Juniperus occidentalis, Hook., both oc- 

 curring sparingly, and a few willows and cottonwoods along Green 

 and Bear Rivers. The common shrubs of Southern W^yoming were 

 Artemisia tridentata, Pursh,, the most common sage west of Rawlins, 

 known as "mountain sage ' and used as a remedy for mountain 

 fever; the " grease-wood," Obionc ca/iescens, Moq., Rosa blanda, Ait., 

 Spiraea diimosa, Nutt., Berheris aquifolium, Pursh., and SympJwricar- 

 pus occidentalism R. Br. 



Among the more common herbaceous plants were noticed Bi^e- 

 lovia {Lynosyris) graveolciis, Gray, as very abundant; Opuntia Mis- 

 souriensis, DC; Cleome integrifolia, T. & G.; Ranunculus Cynibalaria, 

 Pursh; Glycyrrhizahpidota, Nutt., with its prickly legumes; Lupinus 

 argenteus, Pursh, var. argophyllus, Watson ; and Chcnopodium album, L. 



The tree flora of the foot-hills in Eastern Colorado was found to 

 be much more abundant than that of Southern Wyoming. Pinus 

 pmderosa,'Doug\., known as yellow pine, was very plentiful, and attained 

 there a height of 80 to 100 ft., and was a very valuable timber tree 

 Finns eduhs, Engelm., the " pinon " of the Mexicans, was a small 

 tree extendmg as far north as Colorado Springs ; Juniperus Vir- 

 giniana-L., was occasional; Abies Douglasii, Lindl., was quite plentiful 

 at middle elevations, attaining a height of 75 ft., and known as 



swamp pme; 



■tifolia 



balsamifi 



frequent along the streams; Salix nigra, Marsh., var. amygdaloides, 



Anders., and Negundo aceroides xvere frequent along the Platte 



.'■^V J"^^ '^°st abundant shrubs were Quercus alba, L., var. Gun- 



msoni, Torr., the only oak of the foot-hills, except Q. Emoryi, Torr , 



which was scarce, and was a scrub-oak, seldom rising higher than 10 



ft. and occurring plentifully on the dry slopes ; Cercocarpus parvi- 



Joltus, Nutt; Spiraea dumosa, Nutt.; Prunus Americana, Marsh.; 



Vitisriparia, Michx., and Acerglabrum, Torr., the mountain maple. 



_ The more common herbaceous plants were Artemisia Ludovi-
