oxyphylla"? Rich in Frankl 1st Journ, ed. 2, App. p. 28, (not Pall and De Cand.) 



Hab. a. On limestone rocks of the Red Hirer, and south towards Pembina. Douglas. /3. From 

 Cumberland-House on the Saskatchawan, north to FortrFranklin and the Bear Lake, and west to the dry 

 Prairies of the Rocky Mountains. Dr. Richardson ; Drummond.-~Thh belongs to the same groupe of 

 '\VertxciUares" with the true O. oxyphylla of Pallas, which I possess from Pallas' Herbarium, through the 

 kindness of Mr. Lambert; and which is at once distinguished from this by its short, broad, and compact head 

 of flowers. It well deserves the name which Mr. Douglas has given it Its blossoms are bright-blue, in 

 long spikes. In Dr. Richardson's specimens, the fruit greatly exceeds the calyx in length; in Mr. Douglas', 

 it is shorter; but as many of the flowers among the latter are abortive, I suspect that the fruit is imperfect too.

Hab. Banks of the Saskatchawan. Dr. Richardson ; Drummond. — The flowers of this species are very 

 small ; its fruit large and pendulous. The American specimens exactly agree with those in my Herbarium 

 from Lake Baikal.
