This is the species which has generally. been known as Z. Reinwardtit, 
the plant of Java and Ceylon; that has the leaves spinulose-denticulate 
from the teeth of Z. Reinwardtii. It is described in the Fl. N.Z. as ‘‘ var. B 
foliis minus dentatis subintegris,” with the remark that the peristome 
- anomalus has been considered by various authors as synonymous 
with Z. Reinwardtii, but Fleischer (Musei_. . von Buitenzorg, ii) 
retains both species as independent, and on the whole this seems the most 
satisfactory treatment. The erences are no do ight, consisting 
almost entirely in the leaves toothed in Z Reinwardtii, entire or nearl 
so in Z. anomalus, and the inflorescence polygamous (synoicous and 
dioicous) in the former, synoicous in the latter. The outer peristome exists 
in both. 
All the New Zealand and Australian plants belong to Z. anomalus, 
under this name. I have seen no Australian plants with the definite 
spinulose toothing (cf. Plate IX, fig. 3a) of Z. Reinwardtii. If both forms 
occurred there side by side, as in Java, I should think it strong evidence 
that one was a derivative of the other only. 
he nerve is sometimes described as excurrent and forming a mucro, 
but it appears to me to cease nearly always below the apex, and the fine 
mucro not to be formed by the nerve. 
Z. anomalus is the most robust of the New Zealand species, and, being 
synoicous, is more frequently and abundantly fruiting than Z. intermedius 
and Z. Brownii. It is also known from these by the larger leaves with more 
or less waved margins. It is probably more or less distributed throughout 
New Zealand.

_ The commonest. species in New Zealand, and with a very wide 
geographical area. It scarcely differs, moreover, from the European 
- conoideus. It occurs in Java (Z. affinis Doz. & Molk.), fide Lindberg. It 
is known from Z. Brownéi by the peristome only. from the remaining species
