2y Vermischte neue Diagnosen. 



This variety is remarkable on account of the impressed veins. This 

 genus is rather limited to the north temperate regions; one species in 

 Sikkim-Himalaya, two in Central China. The Mt. Morrizon will perhaps 

 be the southern limit in the distribution of the genus Pyrola as it has 

 yet been found nowhere else within the tropic of cancer.

228. Antennaria Athabascensis E. L. Greene in Ottawa Nat., 1906, 

 6. Jan. 



Stout and low, the pistillate plant at flowering only 2 to 2^2 inches 

 high, the spread of the depressed and rosulate foliage in some approach- 

 ing 3 inches: leaves subcoriaceous, spatulate-obovate, very obtuse, 

 without evident mucro, the peliolar basal part not at all well differen- 

 tiated and short, upper face dull pale green, glabrous except as to some 

 rolls of light loose flocculent or cottony wool along the margin, beneath 

 densely silvery, tomentose, some of the tomentum projecting beyond the 

 edge of the leaf and appearing from above as a white margin to the 

 leaf: inflorescence of 3 to 5 large sessile heads: involucre loosely tomen- 

 tose at base, the bracts all with very long white tips, the outer broad 

 and nearly truncate, the next narrower and acutish, the inmost series 

 fairly subulate and exceedig all the others in length: male plant 

 not seen. 



Port Chippweyan, Athabasca, 4 June, 1903, Edward A. Preble; type 

 specimens in U. S. Herb. A very strongly marked member of the group 

 of A. neglecta, but a coarse and stout plant as to habit, though low in 

 stature. The heads are as large as those of the Rocky Mountain A, 

 aprica, but in character very different from those of that species.

230. Pentstemon Gormani Greene, 1. c, p. 39. 



Less than a foot high, the firm basal leaves spatulate-oblong, ob- 

 tuse, entire, 2 inches long including the short petiole, glabrous, the 

 cauline oblong-linear or spatulate-oblong, sessile, the uppermost of these, 

 as well as the inflorescence villous or hirsutulous with gland-tipped 

 hairs: sepals lanceolate, acute, villous-hairy: corolla purple, about : V*
