T. subulata is easily recognized by its broad pale green leaves and long 

 capsules, but varies considerably in the marginal cells of the leaves. T. 

 mucronifolia SCHWAEG. has not been recorded as British, but appears to be only 

 a variety of subulata with a shorter capsule and smooth leaves. T. inermis 

 MONT, is a closely allied species, with oblong obtuse muticous leaves, strongly 

 revolute at the margin, and more minutely areolate ; it should be sought for 

 in the S.W. of England, as it is found in France and Portugal. 



15. TORTULA ANGUSTATA Wils. 



Autoicous ; resembling T. subulata, but more slender. Leaves 

 lanceolate, acute, with a narrow thickened border, obtusely serrate 

 above. Caps, cylindric, narrow, subarcuate. (T. XXXII, C.)

Autoicous ; resembling T. subulata, but more slender. Leaves 

 narrowly ovato-lanceolate, tapering into a very acute point, erecto- 

 patent when moist, erect and less twisted when dry, subserrated 

 toward apex, margin incrassate, of very long narrow hyaline smooth 

 cells. Calyptra more glossy ; seta longer and more slender, twisted to 

 the right below, to the left above ; caps, paler, suberect, long, narrowly 

 cylindric, per. paler, tubular for three-fourths its length, lid longer and 

 more acute.

Although generally regarded as a variety of subulata, this moss has all 

 the appearance of a distinct species, and this view the characters and figures 

 here given will we think sufficiently confirm. 



Sect. 3. SYNTRICHIA (End.). Stems tall, branched ; leaves large, 

 oblong, obtuse, the nerve usually piliformi-aristate. Peristome tubular 

 below, striato-tessellate. 



1 6. TORTULA MUTICA Lindb. 



Dioicous ; caespitose, dark dull green. Leaves spathulate-ovate, 

 obtuse, emarginate, nerved to apex. Caps, cylindraceous, annulus 

 simple, peristome tubular in lower third part. (T. XXXII, D.)
