THE PLANT WORLD. 



ley of Mexico, calling them Bryoziphiuiu Norvegiciim. In thus found- 

 ing a new genus for these specimens he recognized the fact that they 

 were distinct from the other tropical species of Eustichia, and his ge- 

 neric name, Bryoziphium, is the first to separate by themselves these 

 curious, much misnamed mosses. 



In 1892 M Bescherelle revised the genus, adopted Mitten's name 

 for it and recognized three species of Bryoziphium, B. Norvegiciim 

 (Brid.) Mitt., B. Savatteri (Kusn.) Mitt., and B. Mexicamiin Besch. 

 I have called attention to the fact in the Bulletin of the Torrey Botan- 

 ical Club that there still exists an older name for B Savatieri as 

 pointed out by Geheeb, and that Berggren described it as Eustichia 

 Japonic a two years before Husnot named it in honor of its discoverer, 

 so that the same fatality still pursues the members of this cosmopoli- 

 tan family. How they came to be scattered in such diverse quarters 

 of the globe as Iceland, the United States, Mexico and Japan still re- 

 mains a mystery, as well as the fact that in spite of producing an 

 abundance of reproductive organs they still fruit so rarely. That this 

 is the case is evident, for Dr. Chas. R. Barnes, and two of his stu- 

 dents, Messrs. Cheney and True, searched diligently for the fruit for 

 several years in the same locality where I had found it, and it was not 

 until eleven years afterward that Mr. Cheney was fortunate enough to 

 find it again. I visited the Dells again when the American Associa- 

 tion for the Advancement of Science met at Madison in 1893, and was 

 much disappointed not to be able to obtain some fruiting, though we 

 gathered enough of it wherever we saw it growing in fine condition to 

 supply all the readers of this journal who wish to study it. 



Perhaps the best description of it is still that originally given by 

 Sullivant : 



" Stems frond-like, flat, mostly simple (about one inch long and one line broad), 

 rooting only at the bulb-like base; leaves two-ranked, complicate, closely imbricat- 

 ing, erect (straight), those on the middle of the stem elongated -oblong, obliquely 

 truncate, shortly acuminate, increasing in size as they ascend; the perichaetial leaves 

 attenuated into a long and linear, flexuous, pellucid, flat, equitant, and slightly ser- 

 rulate point longer than the lamina ; areolation above subrotund, below oblong, that 

 of the point of the perichaetial leaves linear; costa percurrent, its upper part winged: 

 dicEcious; flowers of both kinds terminal." 



The description of the fruit is taken from the one originally pub- 

 lished by me in the Bulletin of the Torrey Botanical Club, in 1883: — 

 "Capsule terminal, pendent, pyriform i°ini. long and about half as 

 broad when moist, noticeable by its yellow color, supported on a 

 curved pedicel which slightly exceeds the length of the capsule ; teeth 

 none: columella a straight rod persistently attached to the opercu- 

 lum which is conic when moist, flattening when dry, bearing the ob- 

 lique rostrum prominently projecting; calyptra cucullate, .7510™- long,
