MYRINIA. 369 



Hab. About the roots of trees near water. Rare. Fr. summer. 



Resembling slender forms of Leskea polycarfta, but differing in the smaller, less 

 secund leaves with faint nerve and smooth cells. The two species are frequently 

 found together. The fruit is usually produced in abundance. 



91. ANTITRICHIA Brid. 



Secondary stems elongated, procumbent or pendulous, more 

 or less pinnately branched ; leaves ovate-acuminate, denticulate 

 above, single-nerved. Capsule on a straight or flexuose seta, 

 elliptical ; annulus narrow, calyptra cucullate, not covering the 

 whole capsule ; peristome double, inner of 16 filiform, fragile 

 processes, without a basal membrane. Dioicous. 



Bridel's name was given to indicate the supposition, based 

 however on erroneous observation, that the processes were 

 opposite to, not alternate with, the outer teeth. 



1. Antitrichia curtipendula Brid. (Hypnum curtipendulum'L.') 



(Tab. L. A.). 



Secondary stems long, 4-12 inches, robust, more or less 

 regularly pinnate, in loose tufts or masses, olive-green or 

 yellowish. Leaves densely imbricated, spreading when moist, 

 erect when dry, almost always falcato-secund, widely ovate from 

 a broad insertion, gradually acuminate to a more or less tapering 

 point, large, 1-1% lines long, irregularly plicate, slightly 

 decurrent, margin strongly revolute from base to near summit, 

 sharply dentate at apex, the teeth strong and sometimes recurved, 

 especially at the extreme tip ; nerve wide, but not very distinct, 

 reaching % of the length of the leaf. Areolation very small, 

 smooth, elliptical with a sigmoid curve, at mid-base rather longer 

 and narrower, at basal margins short, irregularly rounded, in 

 numerous rows. Pericha^tial bracts long, sheathing. Seta about 

 half an inch long, curved or flexuose ; capsule large, elliptical, 

 reddish brown, paler at first, somewhat narrowed at the often 

 slightly oblique mouth ; calyptra smooth, with a long subulate 

 beak, reaching to about the middle of the capsule ; lid shortly 

 rostellate. Peristome short, pale yellow. 



Hab. Rocks and trees, principally in mountainous districts ; not common. Fr. 

 rare, spring. 



This fine species somewhat resembles Hylocomium loreum in appearance, but the 

 leaves are more densely imbricated with much shorter acumen, giving a very different 

 appearance to the stem when closely examined. In some of its short, slender states 

 it simulates the very rare Hyl. Oakesii, which however is a less robust and rigid plant
