294 BRYOLOGY OF NEW ZEALAND. 
2. Hypopterygium filiculaeforme (Hedw.) ~~ Bry. univ. ii, 712 
(1827) ; Fl. N.Z. ii, 117; Handb. N.Z. F1., 87. 
Syn. Leskea filiculaeformis Hedw. Sp. one p- 212 (1801). 
This very beautiful, endemic species scarcely needs description. 
The usually tall, bare stipes, the large fan-shaped, bright green frond, 
with the branches densely bipinnate and the small neat foliation dis- 
tinguish it from all the other species. 
Subgenus III. STEPHANOBASIS. 
Habit of Eu-Hypopterygium. Amphigastria unbordered, strongly 
serrate. Long, rigid bristle-like setae present in the leaf-axils. 
a. Hy pomteryesn petigery (P. Beauv.) H. f. & W., Fl. N.Z., ii, 118

Syn. Hypnum setigerum P. Beauv., Prodr., p. 70 (1805).

gium tamariscinum Brid. Bry. eit ii, 715; Handb. N.Z.

fulum Col. in Trans. N.Z. Inst., xx, 349 (188 a )s 
Recognized at once by its fairly robust, tall, lax habit and branch- 
ing, the sharp toothing of the leaves and of the very narrow, unbor 
ies amphigastria, and the siineroen long setae arising from tie 
axils on ee side of the under — of fs branches. These only 
occur in one other (American) species; the degen of them in 
the ‘‘ Han abook’” nae H. rotulatum # erroneous. The seta in the 
present species is short and very stout, especially at apex, and the 
wide base of the capsule is highly corrugated or tuberculate. 
The confusion in the nomenclature arises from the fact that Swartz 
originally described Hypnum Tamarisci from a West Indian species, 
with which he believed the Australasian plant to be yes gre Hed- 
wig in the Species Muscorum followed him in this, figured th 
Australasian, pe Rene plant, as if it were the type of rt Tama arisci, 
which, however, is not the case, and the name Yamarisct must be 
restricted to the American moss. C. Mueller in the Synopsis, recog- 
lant, but this was unnecessary, as Palisot had already given it the 
name setigerum. 
Subgenus IV. Ev-HypopreryGium.

fan-shaped, pinnate ¥ plone, Leaves of moderate size, bor- 
peg Axillary bristles
