Dalton 
A most beautiful little flaccid and tender species, of a pale straw colour, with the calyptra exactly as in Asesor 
splachnoides, Schwaeg., whence the species will form a connecting link between Daltonia and Hookeria (Pterigophyllum, 
Brid.). It is not improbable that this curious structure of the calyptra, which appears to be of very rare occurrence 
in the genus, may, in conjunction with the erect theca and some other peculiarities, prove of sufficient importance 
to separate these species from all other Hookeria.

Has. Lord Auckland's group and Campbell’s Island; in wet and marshy places, not uncommon, rare 
in fruit, which was only seen in the former locality.

tum, rectum, theca brevius. Calyptra conico-mitreeformis, glabra, carnosa, rufo-fusca. 
Our specimens want both the operculum and calyptra, the descriptions of which are taken from Tasmanian 
specimens. This species bears much affinity to H. quadrifaria, but is smaller and readily distinguishable by its 
dentate leaves. In general aspect it approaches the H. cristata.

Var. B, minor; foliis rotundatis concavis fusco-olivaceis. (TAB. LXII. Fig. IIT.) 
Haz. Lord Auckland's group; in the dark woods, barren: var. 8, on decaying stumps of trees by a 
water-course, also barren. 
The var. B is certainly not entitled to rank as a species, though at first sight its difference appears striking. 
Another form, probably also a variety, with very narrow leaves, has been sent from Assam by Mr. Griffith, under 
the name of Neckera Adiantum, Griff. MSS. Hookeria pennata, on account of its accessory leaves (stipules), ap- 
pears most naturally allied to those species included by Bridel in Hypopterygium ; it is only in the much advanced 
state that the vaginula becomes hollow and cup-shaped, whence Bridel’s name of Cyathophorum is scarcely tenable, 
considering that the vaginula in other species of Hookeria is very turgid. The calyptra is truly mitriform. 
We have New Zealand specimens of this magnificent moss, nearly a foot long and loaded with thece.
