16 Greene Diagnoses Aragallorum. 



longer white hairs, the oblong obtuse teeth of half 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 me 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. 



Aragallus Macounii sp. nov. 



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

 slightly decumbent scapes a foot high or more, the as nearly upright leaves 

 more than half as high, rather long-petioled ; leaflets in 11 to 15 pairs, 

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

 not crowded ; spikes 1 to 2 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 J inch long, white ; pods villous, small for the plant, little 

 more than the beak exserted beyond the calyx-teeth. 



Plains of Alberta, about Calgary, June and July, 1897, Mr. John Macoun, 

 Nos. 18,516 and 18,517 Herb. Geol. Surv., Canad., named " 0. Lamberti" 

 but allied to A. monticola rather. Type in my herbarium. 



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 numerous and almost crowded, narrowly lance- 

 linear, \ inch long or more, acute ; flowers white, very few, 5 to 12 in 

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

 this cylindric with short teeth ; pods not seen.

 Macoun, No. 5358 as in my herbarium. 



Aragallus galioides sp. nov. 



Slender, 12 to 18 inches high, young parts silvery-silky, otherwise cin 

 ereous- villous ; leaves upright, 4 to 10 inches long, the small oblong acute 

 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 calyx, this densely villous, its subulate teeth 

 more than half as long as the tube; pods short, oval with a long beak-like 

 apex, the whole scarcely f inch long, thin-walled, villous-tomentulose. 



Meadows along Bow River, near Banff, B. C., at 4,500 feet, July and Sep 

 tember, 1899, W. C. McCalla, in U. S. Herb. Elegant small flowered species 

 related to A.splendens; the long leaves with whorled leaflets recalling leafy
