The KATtlRALlST, 



extending above the middle of the leaf; the leaf-cells above more 

 rhomboid, in the middle of the leaf somewhat winding almost fusi- 

 form, yet proportionately always short and wide, at the base of the leaf 

 rhomboid-hexagonal, in the angles of the leaf rectangular yet not 

 concave ; the large flower-buds rooting at their base contain both 

 sexual organs, yet each are separate, and are surrounded by their own 

 involucral leaves, whereby the young flower-buds often appear to be 

 only male ; if, however, they are unfolded they show in the inside the 

 rudimentary archegonia surrounded by the yet less developed peri- 

 chsetial leaves. All the involucral leaves are nerveless, and of a looser 

 cellular texture, the inner perichsetial leaves erect, lengthened out 

 lanceolately ; drawn out abruptly into a moderately long point ; 

 pedicel about 1 cm. long ; capsule cernuous j operculum high conical, 

 red. 



A longitudinal section of the capsule shows between the operculum 

 and the theca two large cells, which probably form the annulus, but 

 whose character, as also that of the peristome and spores, can only be 

 determined from .the perfectly ripe capsule. The spores probably 

 ripen in autumn. 



Discovered by J. Breidler in four different stations, all in the 

 neighbourhood of Schladming, in Styria, about 2000 metres high. 



This species has already a previous history ; my friend J. Breidler 

 sent me the first specimens of it as Limnobium palustre, male, dioicous (1), 

 and communicated to me that Juratzka held it to be Hypnum palustre. 

 Schimper, on the contrary, had declared it to be an unknown Limnobium 

 which he doubted belonged to Hypnum palustre. This new species is 

 distinguished from all allied ones by its synoicous inflorescence. It pos- 

 sesses a certain similarity in habit to Hypnum palustre, it however 

 shows, in a cross section of the leaf, shorter and wider cells, leaf- 

 angles never concave, and a constantly stronger furcate nerve. 



From weaker forms of B.ypmm cocJilearifolium it is easy to distin- 

 guish it by the form and pointing of the leaves.

Of this species (as of many others) Schimper has, in the 2nd ed. of 

 the " Synopsis," (1876) taken no notice, and consequently 

 describes I.e. p. 778, a perfectly sterile plant from the Pyrenees, as 

 Hypnum Goulardi, Schimp., n. sp., which belongs here. Yenturi has 

 himself, even in " Bryinese ex regione italica Tirolis, Tridentina 

 dicta," Revue Bryol.," 1879, p. 62, placed before it Schimper's 

 name (here written in error H. Gounodii and cochleariforme), but the
