. XXXIV.—CATALOGUE OF PHANOGAMOUS AND VASCULAR 
“ORYPTOGAMOUS PLANTS COLLECTED DURING THE SUF 
_-MERS OF 1873 AND 1874 IN DAKOTA AND MONTANA ALONG 
‘THE FORTY-NINTH PARALLEL BY DR. ELLIOTT COUES U. S. 
- A-: WITH WHICH ARE INCORPORATED THOSE COLLECTED 
__ IN THE SAME REGION AT THE SAME TIMES BY MR. GEORGE 
ML. DAWSON. 


/ 


By Pror. J. W. CHICKERING. 


aS The e present article is based primarily upon the collection of plants made by me 
during my connection with the United States Northern Boundary Commission. Those 
Bs co lected i in 1873 were sectired along the northern border of Dakota, in the valleys of the 
Red River of the North and of the Souris or Mouse River; and notably at Pembina, Dak. 
¢ collecting season of 1874 was along tke northern border of Montana, and in the 
ocky Mountains, at latitude 49° N. 
With the species represented in my own collection, Professor Chickering has, at my 
hee gestion, incorporated those procured by my colleague of the British contingent of 


the Survey, as published by Mr. Dawson in his report (8vo, Montreal, 1875, pp. 351-379); 
oe ereby presenting a fair idea of the flora of the belt of country surveyed by the 
} Boundary Commission. The species not represented in my collection, but derived 
_ from Mr. Dawson’s list, are marked with the asterisk (*). 

¥ For papers on other portions of my collections, see this Bulletin, this Vol., No. 1, 
De . 259-292 ; No. 2, pp. 481-518; No. 3, pp. 545-661; No. 4, pp. 777-799.—ED. ] 


This catalogue comprises 692 species, besides quite a number of vari- 

= Pag and is of much value and interest, not so much for the number of 

ee new species enumerated as for the information supplied respecting the 

oy » range of many species known to be common farther east, west, or 

> South. 

e __ A hasty comparison gives about 390 species found in New York or 
_ New England, about 80 distinctively Western in their habitat, and about 
215 which belong on the plains and the Rocky Mountain region. 

v E _ The Leguminose and the Composite are, of course, very largely rep- 
resented, and exhibit a number of species peculiar to the region. The 
- fact that but few collections were made previous to June will explain. 

isi absence of many spring flowers, which, from, the character of the 

2 flora of sunmer, we should expect to find on that parallel. 

. Allium stellatum, Nutt., Anemone Pennsylvanica, L., and Campanu' a 0- 
 tundifolia, L., var. inifolia, were noticed as so abundant on the prairie as 

i to Bive charactan to the landscape. 

. Yucca angustifolia, Nutt., was collected along the Missouri River, prob- 
_ ably reaching here its noeeneat limit.

The species common to this region and the East show, for the most 
part, the effect of the drier climate and the scorching sun of the plains 


‘in smaller, thicker, more hirsute leaves. 


Among the Cactacece but two species are found, Mammillaria vivipara 
and Opuntia Missouriensis, quite abundant along the central region, from 
103° to 111° west longitude, limited very abruptly by increasing moist- 
ure of soil and climate. 

Salicornia herbacea and Rumex maritimus suggest the saline character 
of the soil, and flourish as luxuriantly as if the sea still washed those 
inland shores. ' . 

The paucity in species of trees, excepting Conifere, is in striking 
contrast to the variety of the East, and may in part arise from the 
fact that so.many trees are out of flower before the beginning of June. 

The Orchidacece would naturally be poorly represented. 

Carices and Graminee are quite abundant and interesting, while 
Filices make but-a scanty display. 

Doubtless a careful examination of certain localities through the entire 
season would add many species to the list, but the present catalogue 
serves very well to convey to the botanist a good idea of the character- 
istic flora of the 49th parallel.
