Northern and Middle Islands : probably common, Colenso, Haast, Hector, etc. 
(N. and S. temperate regions). Messrs. Mitten and Spruce observe that this plant, which is 
annual in temperate regions, becomes perennial in the tropics. 
2. B. truncorum, Bory ; — FI. N. Z. ii. 87. Stems 1-2 in. high. 
Leaves dark green, upper rosulate, spreading and recurved, crisped when dry, 
oblong-obovate, acuminate ; margin thickened, recurved below, serrulate at 
the apex; nerve subexcurrent. Fruitstalk curved at the top, 1-3 in. long. 
Capsule narrowed into the fruitstalk, elongate, cylitidric-pyriform, curved, 
drooping; operculum conical, apiculate.- — FI. Antarct. 134 and 415; FI. 
Tasman, ii. 192 ; B. leptotkecium, Taylor. 
Northern and Middle Islands : common on stumps of trees, etc. Campbell’s 
Island : barren, J. D. H. (Common in the southern hemisphere.) Mitten thinks the 
name leptothecium should be adopted for the New Zealand and Australian moss, whose 
identity with the original Mascarene one is not established. 
3. B. campylothecium, Taylor ; — FI. N. Z. ii. 86. Stems 1-2 in. 
high, tomentose. Leaves pale yellowish, imbricate, coriaceous, erecto-patent, 
uppermost rosulate, but not spreading, appressed when dry, obovate-oblong, 
subacute, obscurely serrulate at the apex, not concave ; margins thickened, 
reflexed ; nerve excurrent as a long point. Fruitstalk slender. Capsule 
pendulous, curved, ovate-oblong or pyriform, with a narrow obconic apo- 
physis ; operculum conical, mamillate. 
Northern and Middle Islands : probably common on trees and rocks, etc. Camp- 
bell’s Island : mixed with B. Billardieri, J. D. II. (Australia and Tasmania.) Taylor’s 
original description was, according to Wilson (Bryol. Brit. 242, in note), taken from two 
Swan River plants, of which one is the true B. Billardieri. Mitten considers this to be 
well distinguished from B. truncorum by the imbricate, not rosulate upper leaves. 
4. B. Billardieri!, Schwcegr. Suppl. t. 76; — FI. N. Z. ii. 86. Stems 
4—1 in. high. Leaves pale green, interrupted, upper rosulate, spreading, 
crisped and waved when dry, ovate-oblong, subacute ; margin not thickened, 
reflexed below ; apex serrulate ; nerve subexcurrent. Fruitstalk stout, curved 
at the top, 2 in. long. Capsule curved, clavate-pyriform, drooping, not 
narrowed into the fruitstalk ; operculum subcorneal. — FI. Antarct. p. 413 ; 
Wils. Bryol. Brit. 242. t. 4. 
Northern Island: moist rocks and trunks, Bay of Islands, Colenso, J. B. H. ; Auck- 
land, Sinclair. When growing in the spray, this becomes of a rigid texture and lurid-green 
colour, the leaves spreading, but hardly rosulate. (Common in the southern hemisphere.) 
5. B. rufescens, Hootc.f. and Wils.; — FI. Tasrn. ii. 192. t. 174./. 1. 
Very closely allied to B. Billardieri, but the stems are more slender. Leaves 
spathulate, softer, reddish-yellow, of looser texture at the base ; nerve reddish ; 
margin scarcely recurved. Capsule clavate, arcuate, rather pendulous ; mouth 
purple. 
Middle Island : Matama river, Otago, in boggy ground. Hector and Buchanan. Mere 
scraps, without fruit, identified by Mitten. The stems and leaves are quite black, except the 
tips, which are yellow-green. (Tasmania.) 
6. B. Wahlenbergii, Scliwcegr. Suppl. t. 70 ; — FI. N. Z. ii. 83. Stems 
4-1 in. long, reddish, erect or ascending. Leaves pale glaucous-green, upper 
lanceolate, lower ovate-acuminate, concave, pellucid ; nerve vanishing near
