past season on the summit of Sulphur Mountain near Banff, British 

 Columbia. The species is related to Saxifraga serpyllifolia and 

 S. chrysantha ; the habit suggests those species but the stems are 

 copiously leafy to the top and the leaves are narrower. The 

 petals are smaller, of a much less brilliant yellow and oblong or 

 ovate-oblong instead of oval-orbicular or obovate as they are in 

 the two related species. 



Galpinsia Toumeyi. 



Perennial from a shrubby base, slender, bright green, puberulent. 

 Stems branching near the base ; branches erect or ascending, wire- 

 like, 1-3 dm. long, usually simple above, leafy, pale when young: 

 leaves numerous, sometimes clustered in axils ; blades linear- 

 spatulate to linear, 1-2 cm. long, acute, entire, with midrib promi- 

 nent beneath, lower ones short -petioled, upper sessile : spikes 

 few-flowered, leafy -bracted : calices very minutely pubescent ; tube 

 slender, 3-5 cm. long ; segments about 1-5 cm. long, their free 

 tips 5-6 mm. long : corolla yellow ; petals orbicular-obovate, 

 1.5 cm. long, undulate: anthers linear, as long as the filaments : 

 capsules linear-prismatic, 2 cm. long.

The species just described is related to Galpinsia Hartwegii, but 

 is of a much more slender build. There are minor characters in the 

 foliage and habit, but one of the more crucial points of difference 



lies in the calyx, where we find the free tips of the segments 5-6 



mm. in length. 



LlMOXIUM LIMBATUM. 



Perennial, bluish green or glaucescent. Leaves basal ; blades 

 leathery, spatulate or oblong-spatulate, 0.5-1.5 dm. long, obtuse 

 °r notched at the apex, prominently nerved beneath in drying ; 

 Petioles shorter than the blades or rarely longer, margined : 

 scapes erect, solitary or several together, corymbosely branched ; 

 branches zigzag, ascending ; spikes in dense terminal corymbs : 

 •"acts suborbicular or sometimes orbicular-oval, obtuse, often 

 eroded at the apex, hyaline-margined : calyx trumpet-shaped with 

 a rlanng limb, nearly 4 mm. long ; tube hirsute ; segments broadly 

 deltoid, apiculate : corollas bright blue. 



In alkaline soil, Texas and New Mexico.
