and the Kamloops districts. These regions, owing to the scant precipi- 
tation and to the nature of the soil, have a flora which strangely contrasts 
with that of the other parts of the British Columbia mainland. 
In the dry belts two floristic subdivisions may be recognized, which, 
however, run more or less into each other and, for this reason, will not be 
dealt with separately. The one subdivision is characterized by so called 
bunch grasses, of which Agropyrum spicatum and Elymus condensatus 
are the most prominent species, and is more or less destitute of forest 
forming trees. The other floristic subdivision of the dry belts is more 
densely wooded, the characteristic tree of theforest being the Yellow Pine 
( Pinus ponderosd). On the whole, the dry belt may be said to be 
parklike in general character. 
Besides the above mentioned plants the following may be noted: 
Eriogonum niveum , E. heracleoides, Atriplex argentea, Thely podium lacinia- 
tum, Lesquerella Douglasii , Ribes cereum, Kuntzia tridentata, Astragalus 
collinus, A. convallarius , A. Purshii , Sphceralcea Munroana , Mentzelia 
albicaulis , M. Icevicaulis , M. integrifolia , Oenothera pallida , 0. andina , 
Phlox longifolia, Gilia aggregata , G. Harknessii , G. pun gens, Collomia 
grandiflora, C. linearis, Pectocarya penicillata, Senecio Thomsoniensis, 
Erigeron concinnus, E. Jilifolius, Chcenactis Douglasii, Chrysothamnus 
nauseosus, C. puberulus, Artemisia trifida, A. tridentata. 
CONCLUSION. 
While it is impossible in a few pages more than to outline briefly 
the general characteristics of the flora of so large a country as Canada 
— a flora represented by nearly 5,000 well defined species and varieties 
of flowering plants — the enumeration of species representative of the 
different zones will, it is hoped, serve to give a fair idea of the flora as 
a whole and help a botanist unfamiliar with a particular region to 
determine what he may find there. Although there is a large and 
growing number of local botanists in Canada the general flora of the 
country is known to few but professional botanists, and it is chiefly 
for the information of the former class, and for those who do not reside 
in Canada, that this article has been written.
