DICRANEI. 271 



flowers not gemmiform as in the last, but consisting of naked 

 axillary antheridia, accompanied by paraphyses. 



o. P. crinita, "Wils. ; densely tufted; leaves oblong and 

 elongato-spathulate, rounded above, rigidly hair-pointed from 

 the excurrent nerve ; sporangium elliptic, scarcely contracted 

 at the mouth, lid obliquely rostrate. — Hook, fy Wils. t. xli. ; 

 (Plate 23, fig. 2.) 



On moist banks on the seacoast. Scotland, south of Eng- 

 land and Channel Islands. Bearing fruit in February. 



Nearly allied to the last, and differing in its more densely 

 tufted mode of growth, its more obovate and obtuse leaves, 

 and stronger nerve. Leaf-cells larger and less filled with 

 chlorophyll ; veil even ; antheridia, as in that, naked and 

 axillary. Not yet found on the Continent. 



6. P. Heimii, Br. ty Schimp. ; tufted ; leaves spreading, 

 elongato-lanceolate, toothed above; margin plane; nerve 

 ceasing at or below the apex ; sporangium obovate or oblong, 

 truncate ; lid obliquely rostrate, adhering to the columella. — 

 Hook. §• Wils. t. vii. ; E. Bot. 1. 1407, 1951. ; (Plate 23, fig. 3.). 



On moist banks, principally near the sea. 



Polygamous ; varying in size and in the leaves. Distin- 

 guished from the small variety of P. truncata by the stouter 

 habit ; the longer, softer leaves, which are toothed above ; the 

 nerve not excurrent; the polygamous inflorescence; the lid 

 lifted up by the columella when the sporangium is ripe, and in 

 its place of growth. It occurs at the Cape of Good Hope, 

 and in several places of the Northern Hemisphere. 



Obdeb XXX. DIORANEI, Mont. 

 Sporangium even or striated ; peristome single, consisting 

 of sixteen teeth, split halfway down ; veil cucullate, naked at 

 the base or fringed. -
