Family Cyperaceae.
The following species, recorded only by J. B. A., should, I think, be struck off the list: (2)Cyperus tenellus, (2)Schoenus tenax, (2)S. pauciflorus, (2)S. axillaris.
*Mariscus ustulatus C. B. Clarke. [J. B. A.]
Peraki: L. C. Near Long Lookout, Island Bay: R. M. L.
Eleocharis acuta R. Br. [J. B. A.]
In damp places, Cashmere Hills: R. M. L.; A. W.
(1)Eleocharis Cunninghamii Boeck. [J. F. A.; J. B. A.]
Lyttelton Hills: L. C. (Possibly in error for the preceding species, though A. W. has found it in Hagley Park.)
(1)E. sphacelata is also recorded by J. B. A.
Scirpus inundatus Poir. [J. B. A.]
Damp spots on Lyttelton Hills: A. W. Doubtless also on Banks Peninsula.
*°Scirpus antarcticus Linn.
Mount Herbert: A. Wall.

*Scirpus sulcatus Thouars var. distigmatosa C. B. Clarke.
Wainui, in watercourses.
Scirpus nodosus Rottb. [J. B. A.]
Lyttelton Hills; Pigeon Bay; Akaroa. Common in dry watercourses and near the seashore.
Scirpus cernuus Vahl.
Salt meadows, Teddington, and elsewhere.
Scirpus frondosus Banks & Sol. [J. F. A.]
Sandhills, Sumner and Taylor's Mistake.
Scirpus americanus Pers.
Ohinitahi; Lake Ellesmere; &c.
Scirpus lacustris Linn.
Heathcote: B. D. Cross.
Scirpus maritimus Linn.
Akaroa: T. Kirk. Lake Ellesmere; Ohinitahi.
J. B. A. gives also (2)Fimbristylis dichotoma, a very improbable inhabitant, being a plant of the warmer portions of the North Island, but (1)Cladium teretifolium may possibly occur. Four species of Gahnia also appear on his list. I have seen none, and if any occur they are by no means common. J. F. A records (2)Lepidosperma tetragona (= Cladium Vauthiera): this may possibly occur, but I have not seen it nearer than Mount Grey.
Cladium glomeratum R. Br. [J. B. A.]
Cashmere Valley: A. W.
*Uncinia rubra Boott.
Abundant, 2,000 ft. and upwards, from Mount Sinclair to Castle Rock.
Uncinia uncinata (Linn. f.) T. Kirk. [J. B. A.]
Common in the forests and elsewhere.
Uncinia leptostachya Raoul. [J. B. A.]
Common in the forest, Akaroa (habitat of type).
Uncinia riparia R. Br. var. Banksii C. B. Clarke.
Mount Pleasant (det. Petrie). Akaroa: A. W.
J. B. A. gives also (1)U. rupestris, which, being one of Raoul's species, is doubtless an inhabitant of the peninsula; but after a close search I am unable to find it. I think it unlikely that there are other forms on the peninsula than those listed above. If this be so, then U. rupestris of Raoul may be included in one of the forms above, possibly U. riparia var. Banksii; though it is to be admitted that none of my specimens coincide exactly with Raoul's illustration.
Carex appressa R. Br.
Near Lyttelton lighthouse: A. Wall A new record.
Carex virgata Sol. [J. B. A.]
Cashmere Valley, below Marley's Road: R. M. L. Stony Bay: J. Andersen!
Carex secta Boott. [J. F. A.; J. B. A.; L. C.]
Not uncommon in swampy places and by the sides of streams—e.g., Teddington; Charteris Bay; Taylor's Mistake (on the shore); Wainui.
![Thumbnail: [Volume 51, 1919 page 383]](/journals/rsnz/images/rsnz_51/thumbnails/rsnz_51_00_0447_0383_ac_02.gif)
Carex breviculmis R. Br. [J. B. A.]
In drier ground, often near the hilltops.
Carex ternaria Forst. f. [J. F. A.; J. B. A.; L. C.]
Common in damper places—indeed, the most abundant species of Carex on the peninsula.
*(1)Carex Colensoi Boott.
Specimens from Castle Rock were identified by Petrie as probably belonging to this species.
*°Carex Raoulii Boott. [J. B. A.]
Akaroa: Raoul.
*Carex Wakatipu Petrie. (Con. Cheeseman.)
Castle Rock, 2,500 ft.
Carex lucida Boott. [J. B. A.; L. C.]
Common in damper spots on the Cashmere Hills, in the neighbourhood of Governor's Bay and Teddington, and possib y elsewhere.
Carex litorosa Bailey.
Heathcote: B. D. Cross.
Carex dissita Sol. [J. B. A.; L. C.]
In pastures and forest; not very common.
*°Carex trifida Cav. [J. B. A.]
Akaroa: Raoul.
*Carex pumila Thunb. [J. B. A.]
Wainui: R. M. L. Akaroa: Raoul.
*Carex flava Linn. var. cataractae B. Br. [J. B. A.]
Top of Castle Rock.
Carex pseudo-cyperus Linn.
Watercourse, Port Levy.
Carex Forsteri Wahl.
By the side of bush-streams, Kaituna, Port Levy; Summit Track beyond Kennedy's Bush, Governor's Bay. Some of the specimens have rather the character of C. semi-Forsteri.
I have paid too little attention to the genus Carex to be able to give a complete list, consequently additional species are to be expected here.
J. B. A. gives in addition (2)C. pyrenaica, (1)C. teretiuscula, (1)C. stellulata, (1)C. testacea, (1)C. inversa, (1)C. vacillans. Some of these probably occur.
