THE PLANTS OF THE PEIBILOF ISLANDS. 563 



obovate, erosdentate, often IJ inches long, yellow, fading greenish; pods 1 inch long, 

 narrow, clavate oblong, 4 to 5 angled, hispid except on the prominent angles or ribs. 



Easily distinct from all other boreal poppies by its narrow capsules, which are 

 almost acute by the ascending position of the 4 or 5 rays of the stigma, thus approxi- 

 mating the scarcely tenable genus Meconopsis. ' 



This beautiful poppy flowers about two weeks later than P. radicatum. It was 

 while collecting the latter species in 1897 that the author's attention was attracted by 

 the leaves of P. macounii, which differ in color as well as shape, etc., from those of 

 P. radicatum. Visiting the same spot later, P. radicatum was found with ripened seeds, 

 while P. macounii was only in flower. It was found in abundance later in the season 

 on other parts of St. Paul Island. 



13. Corydalis pauciflora, Fers.. 



Not uncommon on St. Paul Island, generally in moss. Flowering early it is soon 

 hidden by grass and the foliage of other plants. 



14. ITastnrtium palustre DC. 



Among Mr. Palmer's plants from St. Paul Island were specimens of this species. 

 After carefully looking for it in all locaUties where it was likely to grow but without 

 discovering it, I am forced to the conclusion that Mr. Palmer's specimens were col- 

 lected elsewhere. As I may be mistaken in this, however, I include it in the list. 



15. Draba hirta, L. I 



Draia incana, Merriam's List. 



Common on the edges of cliffs and on sandy slopes, St. Paul Island. 



16. Draba -nvahleubergii, Haitm. 



Eare on exposed hilltops on St. Paul Island. 



17. Nesodraba graadis, Greene, Pittonia, Vol. Ill, p. 253. (Plate LXXXIX.) 



Draba grandis, Langsdorff. 



Peduncles about twice the length of the central tuft of leaves and 5 to 10 inches 

 high; pods nearly 3 lines broad and from orbicular to oval, on ascending pedicels of 

 one-half to three-fourths inch long. 



Common on dampish rocks and cliifs on both islands. 



This is without doubt Gochlearia spathulata DC, collected on St. George and 

 St. Paul islands by Chamisso and Eschscholtz. Fruiting specimens are in general 

 appearance much more like a Cochlearia than a Draba. 



18. Eutrema ed^vardsii, R. Br. . , 



Not rare on uplands; generally growing among moss 



19. Cochlearia ofBcinalis, L. 



Common on both islands. 



20. Cardamine bellidifolia, L. 



Eare on the most exposed parts of the interior of both islands. 



21. Cardamine pratensis, L. 



Common by ponds on both islands. 



22. Cardamine umbeUata, Greene, Pittonia, Vol. Ill, p. 154. (Plate XC.) 



Stems several, 10 to 20 inches high from slender horizontal rootstocks, erect, spar^ 

 ingly leafy to the summit, the herbage glabrous; all the leaves pinnate, the lowest
