1898-1902. No. 2.] VASCULAR PLANTS OF ELLESMERELAND. 57 



d. Ges. naturf. Fr. for the year 1813, but the title-page gives the year 

 of pubhcation as 1816. Even if some part of the volume was printed 

 earlier, that can hardly have been the case with Schlechtendal's paper, 

 which is among the last in the volume, and consequently must be of 

 later date than Pursh's Flora, the more so as the 6lh volume of the 

 same periodical (for 1812), is published in 1814, according to the title- 

 page. From this it follows, that one is obliged, in looking upon P. emar- 

 ginaia, Pursh, and P. nana, Schlecht., as synonyms (which, I think, 

 is inevitable), to use the former name. 



As to the above-quoted name of Trautvetter, it must firstly be 

 mentioned that P. fragiformis is also a herbarium name of Willdenow, 

 which ScHLECHTENDAL has published in the same paper. The name P. 

 fragiformis is indeed to be upheld, but for quite another species, which 

 has its principal distribution in East Asia and the Bering Sea region. 

 It differs from P. emarginata in its broader and more rounded, less 

 deeply incised leaflets, whose teeth are less acute. The whole plant is 

 larger and coarser, leafy up even to the considerably richer inflores- 

 cence. Generally it is less hairy than P. emarginata or at least it has 

 not the long projecting hairs of the stem so prominent as in the latter 

 species. P. fragiformis can rightly be said to bear a certain resem- 

 blance to a Fragaria, which can hardly be said of P. emarginata. 

 The figure of Lehmann (Mon. Potent., T. 15) is rather good, even if it 

 represents a somewhat hairy form; but the figure of Rydberg (Mon. 

 Amer. Potent., T. 31, fig. 1) cannot have been designed from any spe- 

 cimen of the true plant of Schlechtendal, as it has much smaller 

 flowers and more narrow petals. This also accounts for the absence 

 of any distinguishing marks in the description of the three species in 

 Rydberg's monograph. His material for the description of P. fragi- 

 formis, partly at least, has belonged to P. emarginata, for he gives 

 Cape York in Greenland among the places where it is found. He also 

 mentions Alaska, where both species are found, but probably his spe- 

 cimens from there also were P. emarginata. Specimens of the real 

 P. fragiformis I have seen, especially from the Aleutian and other Is- 

 lands in the Bering Sea, and also from Western Esquimaux Land (leg. 

 Seemann), and from Siberia so far east as Patapodskoje at the Yenis- 

 sei River (leg. M. Brenner, ^^7, 1876). Specimens very well in accor- 

 dance with these, lay in the Copenhagen herbarium labelled: "Hort. hot. 

 hafn. 26/6 61, sem. ex hort. Hamburg". Even if these cultivated spe- 

 cimens are somewhat less hairy than the figure of Lehmann indicates,
