VIOLACE.E. 11 



Pass, 19 July, n. 501. What is probably the same alpine or 

 subalpine violet was collected by Mr. Baker at Cameron 

 Pass in northern Colorado, as long ago as 1896. It is 

 also represented in C. S. Sheldon's n. 277, obtained at 

 Berthoud Pass in middle Colorado, 16 Aug., 1884. 



V. INAMCENA. Slender, glabrous, or the peduncles and 

 petioles obscurely and retrosely hirtellous; stems several 

 from the slender roots, but not much developed, often 1 or 

 2 inches long, greatly surpassed by the petioles and leaves, 

 the plant thus appearing almost acaulescent: leaves round- 

 ovate, obtuse, notably cucullate, lightly crenate; stipules 

 subulate-linear, lacerately subpinnatifid : flowers seemingly 

 always, even the earliest, short-pedunculate and apetalous, 

 the small ovoid capsules deflexed. 



In low meadows along the river at Gunnison, 25 July, 

 n. 603. The species seems nearly related to V. retroscabra, 

 though the leaves are not only glabrous but more rounded 

 and cucullate, while in the apetalous character of the 

 flowers, and in form of the fruit, it connects with V. physa- 

 lodes. I also provisionally refer here a plant collected by 

 Mr. Baker at Cameron Pass, northern Colorado, 15 July, 

 1896, though its leaves are less rounded and not cucullate. 



The three species next succeeding are of the yellow- 

 flowered group of caulescent violets. 



V. GOMPHOPETALA. Allied to V. Nuttallii, the crown of 

 the root-bearing few and very short depressed leafy and 

 floriferous branches; the whole plant light-green, with 

 ciliate leaves, and their veins pubescent: leaves from round- 

 ovate in the earliest, to oval and oblong-oval or oval-lanceo- 

 late, the longest 1 J inches long, somewhat repand-denticulate 

 or subentire, marked underneath by fine light almost par- 

 allel veins or nerves, the petiole as long as the blade, slightly
