Tasmaniae," (tab. clxx.,) but all without fructification. Another 

 drawing of that species, with fruit and dissections, is also given 

 by Sir W. J. Hooker, [Ic. Filicum, tab. 112,) which is more in 

 accordance with the New Zealand states of L. tariiim ; but all 

 differ widely from this plant. 



Order IV.— MUSCI.

A. Calyptra nearly gluhrous.

 1. P. polycarpum, sp. nov. 



Stems erect, 2 inches high, rather stout, once forked, bare 

 at base. Leaves 3-^ lines long, thickly set from near base, 

 Bub-patent, spreading and decurved below on stem, subulate, 

 acute, glabrous, flat on upper surface not canaliculate, sub-rigid, 

 opaque, narrowly margined, serrate, nerved throughout, dark- 

 green with brown tips, lurid in age ; bases broad, sub-quadrate, 

 1 line wide, amplexicaul ; cells very minute, sub-orbicular dis- 

 tinct and transverse in the margin of leaf near contraction, 

 narrow linear-oblong in the basal portion ; perichtetial shorter 

 than stem-leaves. Fruit-stalks lateral, slender, erect, 1^ inches 

 long, slightly flexuous, twisted at top, light-red, shining, 4-5 to 

 a branch. Capsule broadly oblong, a little contracted at mouth, 

 sub-horizontal and inclined, 2 lines long, somewhat strumous, 

 flat and slightly concave above, conspicuously 2-angled at the 

 sides (sometimes obscurely 4-angled), semi-terete below ; light- 

 brown (becoming darker in age), shining, mouth orbicular ; 

 teeth 64, rather short, hyaline, acute, sinuses broadly rounded ; 

 the circular epiphragm radiate, margin uneven. Spores 

 circular, transparent at centre. Calyptra longer than capsule, 

 narrow linear, 2^ lines long, straight, red, glabrous, tip obtuse, 

 hirsute at extreme apex ; hairs very short and thick ; mem- 

 branous and lacerate at base.

Ohs. This species will range under Polytrichaddphus, 

 C. Miiell., and is allied to P. mayeUankum , Hedw. It differs 

 however, from that species in its more simple stems, in its 

 leaves being margined and more serrate, with much larger 

 sub-quadrate bases, (resembling those of P. yigantmim, B.o6k., 

 as given by Schwaeg., tab. cccxxv.), and in their not being 

 canaliculate and lamellate ; also, in its slender seta, the sub- 

 strumous form of its capsule with circular mouth, its shorter 

 and more acute teeth with broader sinuses, and its longer 

 calyptra.
