It has not, I ekibee: ae found in fruit, and is only known from 
the North L., where it is endemic and apparently not common. Speci- 
mens so named in herb. Schimper at Kew belong to H. pulchella. H. 
auriculata is endemic in New Zealand. H. pulchella is recorded from 
Tasmania and Norfolk I.; and H. falcifolia from Tasmania. 
EXCLUDED SPECIES. 
H. oblongifolia — Porotrichum oblongifolium. 
PororricuumM Bry. jav. ii, 69 (1863). 
Brotherus has referred Homalia oblongifolia H. f. & W. recently 
to Porotrichum, and I think with reason, as the leaves resemble those 
ot some of the species of that genus very closely, and the fruit agrees. 
The limits, however, of some of the genera of — alliance, Neckera 
Homalia—Porotrichum—Pinnatella—Thamnium, &c., are often very 
diffieult—perhaps impossible—to define aaa ’ Porotrichum is still 
more closely allied. to Thamnium, but is principally separated by the 
peristome tee ih, densely transversely striolate for some distance up in 
Thamnium, papillose i in Porotrichum and not striolate, or quite at the 
se only.

The resemblance to Homalia pulchella, which i aioe describe, 
is rather marked at first view, but becomes slight on closer examina- 
tion. Viewed with the lens the plant in its smaller forms may look 
very much like H. pulchella, but the narrower, oblong ‘abe, less 
closely imbricate, will distinguish it; and in its better developed an 
normal forms the highly undulate leaves, both moist and dry, at once 
separate it. In form the leaves are quite different. In Homalia pul-

very robust and reaches to near the apex; and the apiculus is much
