and they then contrast strongly with the leaves of the fertile stem. This 
is the form that gave rise to the names B. varium, B. varians, and B. hetero- 
folium. The capsule is rather large, elongate, with a neck of equal length, 
and when normal is distinguished from all but B. mucronatum in bein 
curved ; the curving being partly in the neck, and often to a slight extent 
The var. extenuatum is taller, with longer seta, but is united to the type 
by intermediate forms. 
It is, I think, very doubtful whether the species is rightly placed under 
Alpiniformia, but I do not know where better to put it. 
I have little hesitation in referring B. variwm here, but the avsilable 
material is very scanty and sterile. 
B. Leviert (type in herb. Mus. Berolin) is only a slender form of B. curvi- 
collum. I have not been able to examine specimens of B. varians C. M. 
the description agree at all points, but the characters emphasized by 
C. Mueller are exactly those by which B. curvicollum is istinguished. 
Further, C. Mueller adds, “An B. varium H. £. & W.,” which confirms the 
identity with our species.

This was based on specimens collected at Waingaro, Auckland, by 
D. Petrie, and Mr. Petrie has sent me his original gathering. It appears to 
B. laevigatum, but to B. curvicollum ; In fact n find no characters to 
separate it from that except the smaller spores (15-17), rather wide- 
mouthed capsule, and short seta (1-5 em.). eel some doubt as to

in a very short mucro; the margin recurved, not or scarcely bordered. 
The capsule is clavate, pendulous, with a short neck passing rather 
abruptly into the seta. . 
I have seen no New Zealand specimens but the original collected by 
Colenso. It is also recorded from Tasmania.
