Recognized at once by iis long, a8 habit: and very soft tex- 
ture ; far more slender ‘than any forms of the preceding, and with 
narrower leaves. The soft, obtuse, Sete leaves distinguish it 
easily from any of the species of Papi 
The fruit is similar to that of the var. Billardieri ot the preced- 
ing, but smaller, and with much more elongate perichaetia, reaching 
beyond the middle of the seta 
The two plants cited above fr om Hedwigia are but ordinary forms 
of this species. There is nothing whatever in the description of P. 
i pea to suggest any difference from W. mollis. The S. Ameri- 
can Neckera Cumingti is quite identical also with the N.Z. plant. 
While presenting no difficulty with regard to W. cochlearifolia, it 
is quite different as concerns Lemboph yllum ional ors CH £'& 
W.), as W. tecdiie sometimes occurs in shorter, denser, bright green, 
more rigid forms that (in absence of fruit) are very difficult to dis- 
tinguish from that species, which bears a very parallel relationship 
in both habit and fruiting characters to that of W. cochlearifolia in 
comparison with the var. Billardieri; so much so that it seems rather 
inconsistent to keep the present two plants widely separated while 
uniting the two former. In the present case, however, the difference 
of habit is greater, and intermediate forms rare; while I have seen 
no intergrading in the fruiting characters, and the perichaetia are 
arkedly different (that of LD. clandestinum being short, and with 
sidaaiicien inner leaves, as in W. cochlear she a). I have also noted 
a slight difference in the alar cells of the leaves which may be con- 
stant, those of L. clandestinum being elongate with markedly sinuose 
walls, while in W. mollis they are oval or rounded, nearly isodiametri- 
eal, and with the walls not or scarcely sinuose. L. clandestinum is 
also said to 2g autoicous, while the present plant is dioicous. It may 
perhaps be a question whether it would not be better to place the’ 
genus W eymouthia next to Lembophyllum instead of in its present* 
position. 
W. mollis, like the last species, is a frequent moss in New Zealand.

This species now placed in this genus, mostly pendulous, arboreal 
mosses, are to be found under Meteorium in the Fl. N -Z., and Hand- 
book.

The species of this group of Papillaria are difficult to arrange 
and distinguish ; the fruit is extremely rare. Among the very numer-.
