Marlborough, leg. J. H. McMahon (E. A. Hodgson mis., sub no. 17).

In appearance this species resembles P. chilensis. It is characterised by the spur-like spines of the rounded posterior leaf-base, which are separated from the coarse and straight apical teeth by a more or less entire margin.

A very pretty species which at first sight recalls a Distichophyllum. Distinguished by the leaf-shape, soft areolation and ciliatetoothed posterior margin and apex.

On Quintinia, Mt. Moehau, 2700 ft., Coromandel, Auckland. 31.XII.33 (n. 8).

This new and attractive-looking species is easily recognised by its forked stem, longly-exserted, slender perianth with spinous-toothed mouth, and also by its small spinous leaves.

Major, late caespitosa, obscure viridis, opaca. Caulis ad 9 cm. longus, laxe fastigiatim ramosus, cum foliis ca. 4 mm. latus, parum convexus.

Marlborough (South Island), leg. J. H. McMahon, XII.32 (mis. E. A. Hodgson).

A fine species, well distinguished by its particularly broad, obtuse, coarsely toothed leaf-apex and the general leaf shape, which is short in proportion to its breadth. Unfortunately, its habitat is not noted. Probably corticolous.

Damp hollow in tussock land E. of Taupo, leg. K. W. Allison, 2.XII.33 (n. 227).

The distinguishing characteristics of this small pretty plant are the leaf-segments which are 2 cells wide from the base to the apex and of almost uniform breadth, also the surprising regularity of the cells which simulate a transversely articulated band.

In hole in hill, “Kiwi,” Wairoa, leg. E. A. Hodgson, Sept., 1931 (n. 88).

L. tasmanica is the only one of the bifid-leaved Lepidoziae with which this can be compared, but our plant differs in the shallower sinus, in the leaf-segment being 3 cells broad at the base, and in the free, differently shaped involucral leaves.

Shady bank near waterfall, near Atiamuri, leg. K. W. Allison (n. 72).

Distinguished from the other Lepidoziae with asymmetrical 4-lobed leaves, by the peculiar form of the leaf, the large brown leafcells, the cuticle not dotted, also by the very small stipules.

On dead branches of Rosa rubiginosa in shade of manuka, ca. 1000 ft., near Atiamuri, North Island, leg. K. W. Allison, 25.VI.31 (n. 102).

A very distinct species by reason of the cucullate concave leafapex, the very large water-sac and the long corner spine of the lobulus.
