the growth of innovations, a to 2 cm. long", pale,' glossy 

 yellow, twisted in two directions, very slender, arcuate when 

 young, becoming erect before capsules mature. Capsule 

 cylindric, ribbed only at the mouth, U to 2 mm. long, beak- 

 straight or curved, shorter than the capsule, peristome'^bright 

 red, not deep set, teeth split unequally to middle, striolate at 

 base, pale and granulose above, annulus none, spores small, 

 calyptra cucullate, 2 mm. long, beaked, entire. Maturing in 

 summer. 



Differs from European specimens of D. longirostre col- 

 lected by Seringe ; in the longer, paler, more slender, scarcely 

 arcuate pedicels, longer capsules, peristome not deep set, and 

 teeth split only to the middle, more united than figured in 

 the Bryologia Europaea, Table 88. It may be distinguished 

 from Campylopus Virginiciis, also remarkable for it's cadu- 

 cous leaves, by the longer, more slender subulate point, 

 which is entire or minutely serrate and smooth on the back, 

 by the thick base, with inflexed blades, and by the shape of 

 the basal cells at the angles.

Plant slight yellowish green, silky, cespitose ; stems mat- 

 ted with rufous tomentum at base, i to 3 cnL long, a few 

 denudate, roughened by the fragments of the slighfly cadu- 

 cous leaves. Leaves secund or erect-spreading, 4 to 5 mm. 

 long, narrowly subulate from a broad base "i to U mm. 

 long becoming tubular above with inrolled margins,' basal 

 angles not auricled, filled by large hyaline cells to the base 

 of the broad, brown vein, those of the blade oblong or 

 square next the vein becoming spindle-shaped and prosenchy- 

 matous toward the margin, vein thick, excurrent into a den- 

 tate slender tip, rough on back. Dioecious, perichstium 

 5 to 7 mm. long, bracts sheathing half their length, taper- 

 ing to a long, slender, obscurely serrate tip, outer shorter, 

 abruptly subulate, more sharply serrate; pedicels recurved, 

 burying the capsules among the leaves, becoming erect when 

 old, 5 to 8 mm. long, stout and twisted in two directions; 

 capsules pyriform-cylindric with a distinct neck, length 

 about I mm. without the lid. which is as long a? the rest 

 of the capsule, with a straight beak, calyptra cucullate, entire ; 

 peristome red, connivent, teeth deep set, slender, split to 

 middle, or perforate to base, striolate below, granulose 

 above ; annulus none, mouth bordered by a dense, "dark rim. 

 Maturing in summer, old capsules persistent, not sulcate. 



Differs from European specimens of D. longirostre in the 

 structure of the base of the leaf, lacking the suddenlv in-
