ART. I. Description of some New Mosses discovered in South 

 America by Dr. Gilhes ; with a Plate. By Robert Kayk 

 Greville, LL.D. F.L.S. F.R.S.E. &c. 



I. Anictangium orthotrichoides. Gillies* MSS. 



A. caulibus subsimplicibus elongatis caespitosis, foliis attenuato- 

 lanceolatis acutis carinatis nervo percurrente^ capsula rotundato- 

 ovata brevissime pedicellata^ operculo convexo rostro subulato, ca- 

 lyptra basi laciniata primo totam capsulam obtegens. Tab. I. 



Hab. On moist banks near Mendoza^ 3000 feet above the level 

 of the sea. 



Plant growing in dense tufts^ of a yellowish-green colour. Stems 

 mostly simple, half an inch or more in length. Leaves numerous,

 Fruit-stalk terminal, scarcely a line in length. Capsttle erect, 

 roundish ovate, even, pale yellow-brown, reddish at the margin of 

 the stoma which is naked. Lid convex, with a straight subulate 

 beak. Calyptra mitriform, striated, at first completely concealing 

 the young capsule, enveloping it and embracing the fruit-stalk be- 

 neath, at length expanded and laciniated at the base. 



When this moss was placed in my hands, I was led to expect, 

 from the appearance of the calyptra and general character of the 

 stems and foliage, that it would prove to be allied to the Ortho- 

 trichoidea;, and perhaps constitute a second species of Glyphomi- 

 trion. It was with no little surprise, therefore, that I found it to 

 be totally destitute of peristome. According to the principles upon
