us in Hep. Amer. 38 and by Macoun, Can. Hep. 19* Fortu- 

 nately Lindberg, a year earlier than Spruce, had given the species 

 a name that will effectually blot out the confusion arising from 

 the use of the homonym, C. iiniltiflora. 



3. Cephalozia Sullivantiae ( Aust.) 



Jiingermajinia Sullivantiae Aust. Bull. Torn Bot. Club, 3 : 12. 

 1872. (Noty. Siillivaiitii Aust. Proc. Acad. Phila. for 1869 • 221. 

 1869.) 



Gametophyte a short, close-creeping, sparingly branched stem ; 

 leaves whitish, usually spaced, about O.3-O.35 mm. long, two-thirds 

 as wide, strongly narrowed just above the base, somewhat ovate, 

 erect, spreading or nearly horizontal, bifid to one-half or two-thirds 

 their length, with obtuse sinus and acute usually divaricate divi- 

 sions; leaf cells 25-30 // in diameter; dioicous ; perianth at the 

 end of a very short branch, obovate-oblong, 1.2-1.5 mm. long, the 

 mouth deeply lO-cleft; involucral leaves mostly bifid with a large 

 tooth on the outer margin near the middle or towards the base. 

 Sporophyte a short-stalked mostly short oval capsule; mature 

 spores not seen. 



Apparently an uncommon species, seen only as yet from Ohio, 

 whence it was distributed by Sullivant : Muse. Alleg. 241 (as 

 Jtmgerinanma hicuspidata, var. 2) ; Austin also reported it from 

 Illinois, but I have seen no specimens. The name is unfortunately 

 too near C. Sullivaiitii and may need change to prevent confu- 

 sion. 



4. Cephalozia catenulata (Huben.) Spruce, On Cephalozia, 33. 



1882.

* In my set of Macoun's Canadian Hepaticae this species occurs under the fol- 

 lowing numbers : 



No. 39 as Cephalozia Lammersiana. 



No. 18 as Cephalozia catenulata. 



No. 20 (mostly) as Cephalozia pleniceps. 

 The species thus appears in one set of exsiccatae under four distinct names ! The 

 smaller species of Hepaticae, like Cephalozia and Marsupella, are likely to grow in- 

 termixed, so that the greatest care is necessary in selecting them for issues of exsic- 

 catae wh ch are to be used as works of reference. Spruce has called attention to the 

 similar errors in European exsiccatae, particularly Gottsche and Rabenhorst's Hepa- 

 ticae Europeae.
