Cells small, roundish-quadrate, strongly and uniformly thickened, 

 without pronounced trigofjes ; cuticle distinctly verruculose. 



Perianth to 3 mm. high, at the apex 1.6 ram. wide, long-exserted, 

 obconic, compressed, its cells strongly incrassate; its mouth decurved, trun- 

 cate and wide, slit down on one side, minutely dentate or frequently en- 

 tire. 



At the apex of the uppermost leaves are numerous ochraceous, oval, 

 one-celled gemmae collected into conspicuous clusters. 



Type locality: Near Washington, District of Columbia, U. S. A., where 

 Mr. J. M. Holzinger collected it abundantly in Rock Creek Park, associated 

 with DitricJnnii pallidjim, kindly sending it to me under the name of 

 Scapania ne/norosa {6.e\.erm. Evans.) To the distinguished hepatologist A. 

 W, Evans, who has done me many kind favors in the past ten years, I have 

 dedicated this species. 



Scapania nemorosa (L. ) Dura. Sii\A Scapaiiia graci/is (Lindb. ), spe- 

 cies without doubt very closely related to it, are distinguished as follows: 



Scapanui nonorosa differs by its greater stature ; by the size of all its 

 parts; by its green color ; by its more branching and flexuous stem, which 

 is less rigid and less radiculose ; by its accrescent leaves, which are less firm, 

 distant, with anterior lobe usually apiculate, erect-spreading (not closely ap- 

 pressed), less convex, with posterior lobe strongly recurved and decurrent, 

 both lobes closely dentate; by the larger, less incrassate cells; and by the 

 raouth of the perianth hardly incised, and densely dentate. 



Scapatiia gracilis 6.\^Qx?, by the greater lengtljof its stem ; by the anterior 

 lobe of the leaves not being ajipressed, and the posterior lobe being only 

 half as large as its corresponding anterior lobe and strongly convex, its upper 

 margin reflexed and decurrent; by the marginal teeth of the leaves being 

 broad at the base; likewise by the cells being more strongly incrassate; by 

 the conspicuous trigones, by the mouth of the perianth being densely set 

 with long and broad teeth, its cells very strongly incrassate.

Died — Prof. Henri Philibert, at Aix, Germany, on May 14, 1901, in his 

 79th year. Deceased was professeur honoraire at the Faculty of Letters in 

 Aix, but he is also known as a bryologist of note. Both Science and 

 Literature will join his bereaved family and friends in mourning his loss.
