( 245 ) 
capsule erect, ovate, 1.25 mm. long without lid, with an ob- 
liquely rostrate lid about .75 mm. long, on a smooth seta 8 or 9 
mm. high; outer peristome with teeth cross-striate below and 
somewhat papillose above; segments of inner peristome nar- 
row, with narrow slits along the median line and sometimes 
very short, rudimentary cilia between; annulus narrow, one 
or two rows of cells high; spores up to 12 4 in diameter. 
Pelichuco, 3350 meters, May 5, 1902, on tree (2773). 
This species is near odli:querostratum, but that is a smaller 
plant with somewhat rough seta, leaf-cells shorter and 
broader and apex of leaf wider. A. /aevisetum has a much 
narrower leaf of different outline. 
DALTONIA LONGIFOLIA Tayl. 
Rio Pelichuco, 1950 meters, April 29, 1902, on trees (2751). 
Santa Barbara, 1800 meters, Aug. 30, 1902 (1816). Taylor 
describes the leaves of this species as ‘‘ integerrimo” but in 
specimens, apparently from the type locality, the leaf is 
minutely serrulate above asin Pelichuco specimens. 
DALTONIA IRRORATA Mitt. 
Sorata, 2500 meters, on tree, Sept. 3, 1901 (2942). These 
specimens were nearly concealed by other mosses growing 
about them and are smaller than the type. 
ADELOTHECIUM BocGoTENsE (Hampe) Mitt. 
Near Apolo, 1800 meters, July 25, 1902 (1965). Hampe 
describes the costa as ending below the apex but in specimens 
of Lindig from apparently the type locality the narrow, 
elongated cells of costa extend into the apiculus in many of 
the leaves just as in these specimens, the colored part of costa 
vanishing in both specimens some distance below apex; also 
the leaf-cells on both surfaces are smooth, not papillose, as 
figured in Engler and Prantl, p. 924. The Apolo plants are 
a little larger, with longer apiculus and margin more dis- 
tinctly crenulate than in Lindig’s specimen, which is not ap- 
parently in the best of condition.
