On the ground, Illinois, E. Hall. 



Remarkable for the obtusish lobes and crenulate margin of the leaves. A 

 Tery small species.

On old logs in woods, hidden among other Jiiti</ermannice, Canada, Macoun ; 

 also near Little Falls, New York. 



About the size and with much the general appearance (when sterile) of 

 small forms of Jungermannia scutata, resembling it in the color, general form, 

 position, and in the areolation of the leaves. Remarkable, among other 

 things, for the light pink color of the amphigastria, with thread- or necklace- 

 form divisions (usually composed of a single row of cells.) Differs from the 

 preceding species in its much smaller size, densely radiculose stems, sliorter 

 and less deeply lobed leaves, &c, ; and from //. minor, Nees., in the more ob- 

 tusely lobed, often entire leaves. The lower leaves are usually rather deeply 

 and acutely lobed, while the upper ones are only emarginate or refuse, or 

 often quite entire at the apex.

Sandwich Islands. Communicated by Dr. H. N. Bolander, (1865.) 



A neat and pretty little plant, about the size of Lejeunia serpyllifolia ; the 

 form of the leaves suggesting a Plagiochila, but the general appearance of the 

 plant is still more suggestive of a Saccogyna, and, indeed, I am not sure but 

 that it ought rather to have been referred to this latter geuus than to Gymnan- 

 the. The cells of the leaves are very large and loosely arranged, and are 

 usually furnished with broad and short projecting points. They also vary 

 greatly in size and position, being roundish or oblong, and frequently some of 

 them are obliquely or even transversely disposed through the leaf. Those on 

 the margin are usually narrower than the others, and vary from subquadrate 

 to elongated-oblong or parallelogrammoid. The cells of the stem are also 

 very loosely disposed ; however, they are still larger than the leaf-cells, and 

 uniformly oblong. 



Calypogeia bifurca, Aust. 



C. albida, caespitosa, parvula ; caule prostrato e ventre apiceque valde 

 flagelifero-raraoso circa 3 — 5 lin. longo, dorso in statu siccati convexo {nee 

 canaliculato) ob cellulis oblongis eleganter striolato perspicue secus foliorum
