in the same localities, we saw nothing at all suggesting intergrading forms, the 

 tufts of 5. strictum being immediately recognizable after we had once distin- 

 guished it. In fact Herr Kaalaas became very adept at recognizing the tufts at 

 a considerable distance by the color alone, which he describes as a "bluish-white" 

 or "bluish-green;" I should call it a whitish or slightly greenish straw-color. In 

 the field it is more likely to be confused with 6". squarrosum than with 6". compactum. 



Two further species of Malaco sphagnum had previously been accredited to 

 North America: 5. sparsifolium Warnstorf, 1894, and S. guatemalense Warnstorf, 

 1890, the former from Guadeloupe, the latter from Guatemala. Warnstorf notes 

 now, however, that 5. sparsifolium was apparently from Africa^ and accuses 

 Cardot (1897) of citing the wrong locality for it, but Warnstorf had himself 

 described it as from Guadeloupe.- It appears, then, in Warnstorf 's latest work as 

 a variety of 5. Pappeanum Carl Miiller, 1849, an African species whose de- 

 scription reads suspiciously like that of S. strictum. S. guatemalense its author 

 has found^ to be a synonym of an interesting species, S. antarcticum Mitten, 

 1859, occurring in the region of Australia and New Zealand, from which region the 

 specimen evidently came instead of from Guatemala. 



Phylogenetically S. strictum is apparently not a derivative of S. compactum 

 nor is the opposite the case, as is shown both by characters and distribution, but 

 their relation is quite analogous to that between 5. magellanicum and the col- 

 lective 5. papillosum-erythrocalyx, viz.: 



Both are evidently old species, as were those of Inophloea. 



To the previous notes upon Inophloea may be added that I have seen por- 

 tions of the types of both 6". portoricense and 6". imbricatum in the Sullivant 

 Herbarium at Harvard University, that the same herbarium contains a specimen 

 of S. portoricense with antheridia sent by Austin, the antheridia being borne 

 essentially as in other species of Inophloea, and finally that S. erythrocalyx was 

 found in New Jersey before Eaton's time, a specimen in the Sullivant Herbarium 

 from Austin bearing notes of this keen observer and the query whether it was not 

 5. tenerum. Sullivant regarded it as a state of 5. cymbifolium, with which 

 Austin later agreed. The locality given for it is "Pines of New Jersey. "

2Hedwigia 33: 320,334. 1894. In Engler & Prantl (I. 3 : 254. 1901.) Warnstorf still 

 had Guadeloupe as the sole locality for it.
