HYPNEI. 115 



sulcate ; branch-leaves narrow, spreading ; all more or less del- 

 toid and amplexicaul at the two-nerved base, attenuated up- 

 wards, and finely serrate; fruitstalk even, about 1 inch high; 

 sporaugia' short, mostly aggregate, roundish-ovate ; lid conical, 

 rather acute. 



In this, as also in H. squamosum and H. loreum, the spo- 

 rangium when dry is frequently slightly ribbed. The species 

 is much used for packing on account of its elasticity. 



60. H. loreum, L. ; stem ascending, arched, simple or di- 

 chotomous ; branches irregularly pinnate ; branchlets elon- 

 gated, often rooting at the end ; leaves crowded, variously 

 directed, ovato-lanceolate, acuminate, minutely toothed, faintly 

 two-nerved, and sulcate at the base ; fruitstalk even ; sporan- 

 gium roundish-ovate, horizontal; lid conical, apiculate. —

In mountainous woods. Bearing fruit, but rarely, in winter 

 and early spring. 



Dioicous ; forming soft, green or olivaceous tufts, some 

 inches long. Stem more or less erect, or at least ascending-, 

 the branches more or less pinnate ; branchlets often rooting 

 at the tips; leaves squarrose, subsecund or even falcate 

 above, ovato-lanceolate, strongly acuminate, slightly serrate, 

 sometimes auriculate, deeply grooved, sometimes nerveless, 

 but generally with two faint veins at the base ; cells narrow 

 throughout ; fruitstalk twisted, an inch or more long, even ; 

 sporangium subglobose, sulcate when dry, horizontal ; lid 

 large, conical, with an acute apex. 



i. Htocomium, ScMmp.* 



61. H. flagellare, Dicks.; stem arched, proliferous; branches 



* Separated by Schimper from Ewrynehiv/m, on account of its conical, not 

 rostrate beak, and slight differences in the reticulation of the leayes.
