80 LAWSON : EBVISION OF THE 



[D. SIMPLEX. Douglas, iu Hook., Fl. Bor.-Am., I., p. 25, is a southern plant found 

 by Douglas on the sub-alpine range, west of the Eocky Mountains, near the Columbia, 

 plentiful ; and by Brewer in the coast ranges south to San Diego. It also occurs in Idaho. 

 Much resembling D. azureum of the eastern plains, but differing in its less strict habit, 

 and looser racemes of larger and more open flowers. (Bot. Calif.) 



5. — Delphinium Ajacis, Rekhenbach. 



Stem erect, divaricately branched. Racemes elongated, rather laxly flowered, pedicels 

 as long as the bracts. Follicles solitary, pubescent. Annual or biennial. Dwarf or 

 Branched Larkspur.

This plant has been known in Cambridgeshire, England, since the days of Dillenius, 

 bïit has not spread there, and, beyond the chalk districts, is little more than a casual 

 straggler. See H. C. "Watson, Cyl)ele Britannica, I., p. 9Y. It may have been brought to 

 Canada in grain or grass seed from England or continental Europe, and seems to find 

 congenial conditions in the light soils overlying the limestones of Ontario. 



The true D. Consolida of Linnœus differs from this species in having shorter glabrous 

 follicles, short racemes, and seeds with interrupted ridges. (Hook, fil.) It is a southern 

 European plant, not native of England, and found only once in a field in Jersey. The 

 Canadian localities hitherto published for "D. Consolida, L." no doubt all belong to D. 

 Ajacis, Reich. The D. Ajacis of my Monograph of Ranunculaceae is D. orientale. Sir Joseph 

 Hooker says: — " Syme observes that D. Ajacis, Reich, (and continental European authors) 

 is not the plant of Linnœus (which is orientale of Gay) ; hence the present plant should 

 have a new name ; but as the names. Consolida, orientale, and Ajacis, are now fixed, it is 

 unwise to disturb the present arrangement." 



6. — Delphinium orientale, J. Gay. 



Stem erect, straight, almost unbranched, whole plant nearly glabrous ; the flowers 

 in a long dense raceme, pedicels as long as the bracts ; capsules pubescent. Annual.
