lonfier white hairs, the oblong obtuse teeth of iialf the length of the tube 

 and wholly black-hairy; pods unknown. 



Species very well marked by its peculiarly obtuse black calyx-teeth. 

 It is known to nie by a sheet in my own herbarium collected by Mr. John 

 Macoun at Elbow River, Alberta, in 1897; the label bearing the Geol. Surv. 

 No. 18,513. 



Arag:allus Macounii sp. nov. 



Growing parts silky-canescent, maturer herbage greener, the erect or 

 slightly decumbent scai)es a foot high or more, the as nearly upright leaves 

 more than half as high, rather long-petioled ; leaflets in 11 to In pairs, 

 ovate-oblong or oblong-lanceolate, acute, often J inch long, approximate but 

 not crowded ; spikes I.7 to 2h inches high ; bracts lanceolate, equalling the 

 calyx-tube, herbaceous; calyx-teeth broadly and somewhat obtusely subu- 

 late, of much less than half the length of the villous-tomentulose subcylin- 

 dric tube ; corollas 4- inch long, white ; pods villous, small for the plant, little 

 more than the beak exserted beyond the calyx-teeth.

Aragallus cervinus sp. nov. 



Slender and rather low, the tallest scapes 8 inches high, these and the 

 leaves erect; herbage silvery-silky, the upper face of leaflets least so, their 

 lower most so, these very numeious and almost crowded, narrowly lance- 

 linear, h inch long or more, acute ; flowers wliite, very few, 5 to 12 in 

 each short capitiform spike; bracts subulate-linear, shorter than the calyx,

 thin leaflets in whorls of 4, approximate but not crowded or imbricate; 

 slender spikes of small flowers 4 to 6 inches long, not dense; bracts linear, 

 nearly equalling the cylindric cal3'x, this densely villous, its subulate teeth
