NO. 1 steere: mosses 3 



branch immediately below the perichaetium; archegonia numerous, 

 their position exceedingly variable, terminal on the main stem, or in 

 axillary buds on the dorsal side of the stem, or on very short to 

 elongated axillary branches which bear rhizoids at their base and 

 are easily detached, all types often on the same plant; sporophytes 

 single or not infrequently 2 from each perichaetium, stages of widely 

 differing ages often occurring on the same plant, or even from the 

 same perichaetium; seta yellow, becoming red shortly after matu- 

 ration of the capsule, 2-4 mm. long, quite variable in length, flexuose; 

 capsule inclined, slightly asymmetric, the urn 0.6-0.7 mm. long, its 

 cells mamillose and projecting, their angles strongly thickened, the 

 neck stomatose; lower half of the peristome teeth red and conspicu- 

 ously incurved, the upper half pale and suddenly erect; operculum 

 conic and long rostrate, as long as the urn; calyptra small, shed 

 very early; spores smooth, small, 12 /x in diameter. 



On clay soil. Port Utria, Choco, Colombia; February 14, 1934; 

 W. R. Taylor No. io8i (type specimen, in the U. S. N. Herbarium). 



This species possesses a combination of characters which serves 

 to distinguish it rather easily from the species most closely related 

 to it. The principal diagnostic characters are the long stems, with 

 an unusually large number of leaf-pairs, the red stem and costa, 

 the serrulate leaf-apex consisting of enlarged, smooth cells, the 

 peculiar growth-habit, and the character of the inflorescence, in- 

 cluding the variable position of the archegonia.
