﻿south-east of Long Island along the coast at Long Reach {Bull. 

 Ton: But. flub, vol. xv. p. 328), and on Nahaut Reach, Mass., it 

 grows on the sea-coast. Though nothing is expressly stated on 

 this head, I believe I am not mistaken in assuming that there this 

 plant appears in the same association as in Europe. 



The significance of this is still further increased by the fact that 

 A. Stelleriana lives in Kamchatka, among quite similar environ- 

 ments. Retween the undermost leaves of some dried fragments 

 of this plant sent me by Maximovicz from Kamchatka, I observed 

 grains of white sand and glumes of some Elymus species. The 

 plants had thus grown in sand and in association with some species 

 of the said genus. If this plant had originated from gardens in 

 Europe and North America, it would be almost impossible to 

 explain how it could have passed over all the interjacent tracts, and 

 found a direct path to localities exactly resembling those which it 

 affects in its first home. 



On the other hand, several difficulties may be raised to the 

 assumption that A. Stelleriana is native to the sea-coasts of Europe 

 and North America. That it has not been observed sooner is 

 almost incomprehensible. This may be explained, however, in 

 some degree by the fact that A. stelleriana occurs on a littoral zone 

 whose vegetation is comparatively uninteresting, and to which no 

 great attention is therefore paid by botanists who visit the shore to 

 examine the saline flora. At a distance, too, it may be mistaken 

 by the casual observer for A. maritima or Absinthium, or even for a 

 whitish tomentose form of A. vulgaris. Even on the supposition 

 that this plant has been brought to Sweden in recent years it must 

 have occurred, as I have tried to show, for some time on the 

 Seaman c ist, although not until 1880 did it attract so much 

 notice that its species was determined. The fact is that it was 

 collected in 1876 by two young botanists, who paid no attention to 

 it, however, until it had been ascertained that A. Stelleriana grew 

 on the west coast of Skane. That this plant appears at isolated 

 points, widely separated from each other, has evidently contributed 

 to the long period during which it remained unobserved. Resides, 

 its flowering season occurs rather late in autumn. On the 22nd 

 September, 1880, it was still in full-flower when I visited, during a 

 botanical excursion, its station, already discovered by a school-boy; 

 and botanical excursions for the collection of phanerogamous 

 plants are seldom undertaken in Sweden so late in the year. It is 

 also far from probable that every spot within an extensive area can 

 have been visited by an experienced botanist. In this manner we 

 may account for the fact that marked species of plants may still be 

 discovered in well-examined tracts. In Skane, for example, which 

 is certainly the most thoroughly examined province in Sweden 

 from the botanist's point of view, there have quite recently been 

 observed, among many others, Lathyrus sphmicus, Hypericum 

 pulchrum, Cirsium rivulare, and Putentilla Fragariastrum ; and on 

 the little island of Rornholm was discovered, about twenty years 

 ago, the extremely well-marked Anemone carulescens Lge., which 

 was in several localities very luxuriant.
