Kirk.—On the Occurrence of Juncus glaucus in New Zealand. 893 
According to Dr. Ascherson, the typical form Z. nana has a wide 
distribution, occurring at the Canary Islands, Mediterranean, North Coast 
of Sicily, Smyrna, Black Sea, Caspian Sea, Portugal, Spain, France, 
British Islands, Holland, Denmark, Holstein, J apan, Cape of Good Hope, 
Port Natal, Nossi Beh. 
Var. muelleri has been collected on the coasts of Chili, South and East 
Australia, Tasmania, and New Zealand. 
Zostera tasmanica, G. v. Martens, is said to occur in New Zealand, but I 
do not know by whom collected. The plant intended is probably that 
referred to in the early part of this paper as Z. marina; but in any case the 
identification cannot be considered satisfactory in the absence of flowers, 
since it is possible that our plant may belong to Phucagrostis, which it 
closely resembles in habit. 
ArT. LV.— Notice of the Occurrence of Juncus glaucus, L., in New Zealand. 
By T. Kars, F.L.S. 
(Read before the Otago Institute, 17th January, 1878.] 
In company with Captain J. Campbell-Walker I had the pleasure of 
discovering this interesting addition to our flora by the road-side between 
Hokitika and Ross, within a mile of the left bank of the Hokitika river. I 
had not time to make a detailed examination of the locality, but Mr. 
Shillitoe, who kindly went over it at my request, informs me that the plant 
occurs plentifully over a considerable area. 
Juncus glaucus bears some resemblance to J. communis, Meyer, but is 
distinguished by its hard texture, interrupted pith, and glaucous striate 
rigid culms; the perianth segments are lanceolate and equal the capsule 
in length ; the capsule is mucronate. 
The culms are two to three feet in length, frequently drooping in large 
specimens, 
In J. communis, var. hexangularis, the pith is sometimes slightly inter- 
rupted, but never to so great an extent as in J. glaucus, from which it may 
always be distinguished by the retuse capsule. 
In all probability Juncus glaucus is not unfrequent on the west coast of 
. the South Island. Itis singular that this species, as well as J. lamprocarpus, 
Ehrhart, should not have been observed earlier. The latter species is 
abundant in the Hokitika district, extending southward to the Bluff and 
northward to Port Nicholson, but is not found on the eastern side of either 
island. In Taranaki and Auckland it is replaced by Juncus holoschenus, 
Thunb, yl
