322 BRYACE^. 



is probably safer to leave undetermined. I learn from Dr. Braithwaite that Lindberg 

 gathered a moss in Ireland identical with this and named it provisionally B. 

 calcareum. I have seen very similar plants from several localities, and am inclined to 

 refer them all to the present species in preference to any other. 



8. Bryum inclinatum Bland. (Pohlia inclinata Sw.) 

 (Tab. XLIII. G.). 



In close compact tufts or wide patches, densely interwoven 

 below with tomentum ; deep or olive green. Leaves frequently 

 interruptedly tufted, the comal crowded, numerous, erecto-patent, 

 when dry erect and appressed forming an oval tuft ; ovate- 

 lanceolate from a rather narrow red base, gradually and acutely 

 acuminate above, usually widest about the middle ; margin 

 reflexed to near apex, entire or slightly denticulate at the point, 

 nerve excurrent in a long denticulate arista or shorter cuspidate 

 point ; cells at base lax, rectangular, above hexagonal-rhom- 

 boid, about twice as long as broad, narrower towards margin and 

 apex, 3-5 rows at margin very narrow and elongate, often yellowish, 

 forming a distinct border reaching to apex. Seta i-iYz 

 inches long, capsule oblong-pyriform or clavate, sometimes a 

 little curved, tapering at the neck, sub-pendulous or inclined, with 

 a narrow mouth, brown or reddish brown ; lid small, apiculate ; 

 peristome teeth yellow, orange at base, transversely articulate, 

 without oblique connecting lines; inner pale, basal membrane 

 adherent to the teeth, processes free, cilia none or very rudi- 

 mentary. S3'noicous or autoicous. 



Hab. Dry heaths, walls, etc. Frequent. Fr. summer. 



This species externally resembles several others of the genus, notably B. 

 pendulum, B. ctzspiticium, B. pallescens, B. intermedium, B. affine, and B. 

 provinciate. The difference in the peristome teeth pointed out under B. pendulum 

 will at once distinguish that species, and indeed forms the only constant distinctive 

 character ; all the others differ in the well-developed, appendiculate cilia ; differences 

 of inflorescence are often adduced, but the inflorescence in both B. inclinatum and 

 B. pendulum is too variable to give these much practical value. The cells in B. 

 caspiticium are usually longer and narrower, the leaves generally broadest below the 

 middle and more gradually tapering ; and the present species is for the most part a 

 larger plant with larger leaves than any of them except B. provinciate ; but on the 

 whole the peristome must be considered the most satisfactory character. B. 

 provinciate differs also in the leaves more regularly arranged in interrupted tufts, 

 wider, especially in the upper part, more rapidly pointed so that the apex is broader, 

 with wider areolation at the point. 



Looser, more elongated forms occasionally occur, with the leaves less crowded 

 and somewhat twisted when dry. Although the capsule is sometimes described as 

 contracted below the mouth, I have never found it so except in capsules which had 

 dried when slightly immature. 



The base of the teeth of the outer peristome is frequently of a very deep red.
