have found the separating characters ‘assigned to the two mostly 
quite unreliable. The breadth of the auricles and their denticulation 
those having a pale border, but I have specimens exactly agreeing 
with the original ot P.flexicaulis showing no difference whatever in 
this respect from P. filipendula. The — must I think be 
based principally on habit and partly on leaf form. I have examined 
the type of Leskea flexicaulis Tayl. in Herb. Bonk. the deseription 
in the Fl. N.Z. applies admirably; it is not a very elongate or delicate 
plant; tha is! yellowish in colour, but sometimes—as in P. filipen- 
dula u y—dull olive green, with the leaves (of the type (a) eee 
ceed: in mer Key) broader and more shortly pointed than in P. fili- 
pendula, in fact somewhat intermediate between that and P. ambly- 
acts. The leaves gradually tapering and rigidly pee ee the 
points distinguish both species from P. amblyacis. 
upper cells in P. flexicaulis are almost identical with those of 
P. crocea, but the pale border is less marked.

e pointed out the distinctive characters between this and P. 
P ies: ip above. It is the most slender and delicaie of the New 
Zealand rete though attenuated forms of P. crocea may approach 
it very closely in this respect. 
Neither P. flexicaulis nor P. filipend ula, Judging from the collec- 
tions I have received, is so common in New "Zealand as the remaining 
species 
F, filipendula is found also in Java. 
3. Papillaria amblyacis (C.M.) Jaeg. Adumbr. ii, 171. 
Syn. Neckera amblyacis C.M. in Linn. xxxxvi, 521 (1869-70). 
This although somewhat variable in size and leaf disposition is. 
nearly always recognizable at once by the terete, julaceous branches. 
when dry, the leaves being very broad, smooth and convex at back, 
very closely and densely imbricated, with a very short and abrupt, 
pale, recurved muecro or cuspidate point. The plant is perma 
yellow or orange, though le ess so than in the following species. It i 
oot 
are similar to those of P. crocea. The nerve is longer than in any of 
the species, reaching nearly to the apex; and is highly pellucid. 
It appears to be common
