138 Rhodora [June 



Morong in his monograph limits this variety to the plants of the 

 shallow pools which have "a compact, bushy habit, leaves 1-3 inches 

 long." This passes without perceptible demarcation to the equally 

 coarse plant with longer leaves and an elongate stem. It seems better 

 and more consistent to include these under the var. Macounii. A 

 plant cited 1 as P. juncifolius Kern, from North Pond, Prince Edward 

 Island, seems to belong here. 



Another American specimen named P. juncifolius Kern, from 

 Labrador, in the Ungava River, Fort Chimo, Aug. 23, 1896, Spread- 

 borough, (C no. 16,471) may be correctly identified, but it is so young 

 that it is difficult to name with any certainty.

LAPPULA DEFLEXA IN VERMONT. 

 J. R. Churchill. 



As a result of my discovery in July, 1914, of a considerable colony 

 of the "Nodding Stiekseed," Lappula deflcxa (Wahlenb.) Garcke, in 

 Derby, Orleans County, Northern Vermont, I have been interested to 

 investigate the history and the range of this attractive though some- 

 what weedy stranger. The plants were growing along one side of 

 the main road leading south from Derby Line, in open country, about 

 a mile from the village. The highway appeared to have been recently, 

 extensively repaired or reconstructed, thus confirming the impression 

 that the plants had been introduced. 



Like all the Stiekseeds L. deflcxa is admirably adapted by its prickly- 

 barbed nutlets to easy and wide distribution by railroads and other 

 carriers. And yet my brief study of this species and its history 

 indicates that, despite these devices for migration, the plant has failed 

 hitherto to extend materially its long recorded range. Lappula defle.va 

 (Kcliino.spmn urn deflexum, Lehm.) is found in Siberia and continental 

 Europe and has long been known in the extreme northwestern United 

 States and the adjacent Canadian provinces. And recent collections 

 by Prof. Fernald and others show that the species is indigenous in
