This minute but distinct little moss is probably not uncommon, but 
may have been overlooked. It exists in R. Brown’s herbarium from Christ- 
church, and I have it from the Lyttelton Hills (coll. Beckett), and from 
Otago (coll. Petrie). The original locality was Hawke’s Bay, North Island.

E. 8. Salmon has gone so fully into the history and synonymy of this 
fine plant in Journ. Bot., 1903, pp. 1, 46, that there is no need to go further 
into it here. He shows clearly that S. Hookeri must be reduced to the 
main species, and, in fact, that Calyptopogon is a monotypic genus, mee 
over a nie part of South America and the greater part of Australas 
nin fruit it is recognized at once by the short seta and ere long 
cathe perichaetium. When sterile (which is usually the case) it is 
easily known by its leaves with their stout white border of narrow cells (Tor- 
tula Poavies Broth. has a similar border, but the resemblance ends here), 
centimetre or so to 4 or 5 centimetres. It rarely fruits, but five fruiting 
specimens were sent to Kew caf R. Brown, and I have received others from

HENNEDIELLA Par., Ind., p. 557 (1894). 
This genus was established as Hennedia by R. Brown ter. in Trans. 
N.Z. Inst., vol. 25, p. 285, for three Bene of mosses, but the name had 
already been preoccupied for a genus o 
They resemble some rine of Pottia in the leaf, which has a denticulate 
apex, and a distinct pale or brown border of elongate or smooth cells, a 
very short seta so that the capsule is ane almost or quite hidden; the 
special character of the genus lies in aa y large campanulate calyptra 
descending to the base of the capsule ; F ecome is wantin 
calyptra is truly campanulate oy near maturity, but as the capsule 
ripens it (sometimes at least) splits the calyptra up one side, and it 
becomes more or less cucullate, still, however, covering the whole or the 
greater part of the capsule.
