General Notes. 127 



The Nodding Pogonia in the vicinity of Washington. 



In August, 1903, while examining the woodland near the alluvial bot- 

 toms on the north side of Plummer's Island, I came unexpectedly upon 

 several clumps of the Nodding Pogonia, Triphora trianthophora (Sw.) 

 Rydberg. This orchid is credited with a range extending from Vermont 

 to Florida, and westward to "Wisconsin and Kansas, but it is everywhere 

 rare and local except in certain portions of the Alleghenies. Certainly 

 its discovery at this point furnishes another important addition to the 

 flora of Washington and vicinity. Plummer's Island, in the Potomac, 

 is located about nine miles from "Washington, and belongs geographically 

 to Montgomery County, Maryland. The central portion is high, rocky, 

 and well timbered, the soil being a fine leaf mold. The basal portions, 

 on the other hand, are level and often flooded when the river is at its 

 highe? stages. 



This orchid has been very generally placed in Pogonia by modern 

 authorities. In Britton's Manual, however, the genus Triphora, which 

 Nuttall established for it, is restored. In the field the plant is certainly 

 conspicuously different in appearance from other Pogonias. This is due 

 mainly to the axillary inflorescence. The only other character of im- 

 portance on which Triphora is based is the absence of a crest on the lip 

 of the corolla. — Charles L. Pollard. 



A new Violet from Kentucky. 



Viola Priceaxa n. sp. — Acaulescent, erect, about 1.3 dm. high, from an 

 oblique rootstock; leaves succulent, glabrous, rather dark green, cordate- 

 ovate in outline, somewhat cucullate, the apex abtuse, the margin regu- 

 larly crenate; scapes equalling or surpassing the foliage; flowers very 

 large (3 cm. broad) pale lilac, shaded with purple near the base of the 

 petals and conspicuously purple-veined; lateral petals copiously bearded 

 with white hairs; petals broadly oblong or nearly orbicular, the keel 

 petal narrower and deeply channeled, the spur large and blunt; cleis- 

 togamous flowers on horizontal or slightly ascending peduncles. 



In rich soil, various stations around Bowling Green, Kentucky. The 

 description is drawn from a clump of plants in my garden, sent to me in 

 May, 1901, by Miss Sadie F. Price; these flowered rather sparsely in April, 

 1902, but more freely in 1903, and were conspicuous when in bloom on 

 account of the contrast between the purple margins and pale ground 

 color of the corolla. Miss Price reported it as very constant in its char- 

 acters, and as easily distinguishable from other violets with which it 

 grew. 



A herbarium specimen taken from these living plants and deposited in 

 the United States National Herbarium, is the type. I take pleasure in 

 naming the species in honor of the lady whose recent decease has de- 

 prived us of a valuable field worker and intelligent collaborator. — Charles 

 L. Pollard.
