278 FLORA OF NEW ZEALAND. | Cyperacee. 
Has. Northern and Middle Islands ; abundant in woods, Banks and Solander, etc. 
A tall, coarse, leafy Sedge, 3 feet high and upwards. Culms stout, leafy ; sheaths slightly rough to the touch. 
Leaves very long, flat or with convolute margins, smooth, ending in very slender filiform points. Panicle erect, 
10-18 inches long, much branched and leafy. Branches not very long, inclined. Spikelets alternate, pedicelled. 
Bracteole and outer scales ovate, aristate, with membranous margins, often downy. Nut black, elliptic-ovate, 
obscurely trigonous, slightly transversely ribbed inside, suspended by the very long filaments.—The ribbing inside 
the nut indicates an approach to Gahnia. 
4. Lampocarya zanthocarpa, Hook. fil.; culmo tereti elato robusto foliisque longissimis convolutis 
levibus striatis, panicula maxima effusa inclinata, ramis elongatis pendulis multifloris, bracteis foliaceis, 
spiculis subalternis puberulis, bracteolis sguamisgue extimis aristatis intimis acutis, filamentis longissimis, 
nuce elliptica utrinque acuta pallide flava trigona nucleo obscure rugoso.—Schoenus xanthocarpus, Banks 
et Sol. MSS. 
Has. Northern Island ; Bast Coast, Banks and Solander, Colenso; Auckland, Sinclair. 
A very fine species, 6-8 feet high, with a stout polished culm, and very long, guite smooth, grassy, coriaceous 
leaves. Panicle 2-8 feet long, nodding, with leafy bracts. Branches very numerous, fascicled, 10 inches long, 
drooping, bearing very numerous spikelets. Scales, Stamens, etc. like those of L. lacera. 
Gen. XIII. GAHNIA, Forst. 
Omnia Lampocarya, sed nuce intus transverse sulcata. 
This Australian and New Zealand genus is known from Lampocarya, by the nut being wrinkled or grooved 
transversely inside, and the seed being correspondingly cut into parallel transverse ridges. The filaments are four 
in the New Zealand species, very much elongated. Stigmas three, or four, in which case one is bifid. ZL. lacera 
has the cavity of the nut partially wrinkled, and should perhaps be placed here, but the seed in my specimens is 
unripe. (Named in honour of Dr. Henry Gahn, a Swedish botanist.) 
1. Gahnia setifolia, Hook. fil.; culmo tereti gracili sublevi, foliis convolutis longissime subulatis 
asperulis apicibus filiformibus, panicula elongata gracili laxiflora, ramis elongatis, bracteis exterioribus 
subulatis ramis pallidis brevioribus, spiculis alternis atris breve pedicellatis, bracteolis spiculis brevioribus 
sguamisgue extimis puberulis aristatis intermediis acuminatis supremis subobtusis, filamentis 4 capillaribus, 
stigmatibus 8-4, nuce rufa elliptica nitida subtrigona apice cuspidata atra.—Lampocarya? A. Rich. Flor. 
Schcenus erythrocarpus, Banks et Sol. MSS. 
Has. Northern Island; common in woods, ete., Banks and Solander, ete. 
A very coarse, cutting, harsh Sedge, 2—4 feet high, with smooth round culm and long subulate convolute 
leaves, ending in scabrous filiform points, Panicle 1-2 feet long, slender, inclined, leafy below. Branches pale, 
contrasting with the black spikelets, slender, much longer than the upper bracts. Spikelets alternate, 2-3 lines long, 
shortly pedicelled. Outer scales and bracts faintly downy, awned; inner scales acuminate, upper blunt ; two of the 
latter often have flowers; the lower with four filaments only, upper with four stamens, and an ovarium with three or 
four stigmas. Nut as long as the spikelets, pale red-brown, shining, obscurely angled, grooved on one side, 
elliptical, with a black point.—Very nearly allied to G. erythrocarpa of Tasmania, but the bractez and scales have 
long awns in this species. 
2. Gahnia procera, Forst.; culmo levi, foliis longissimis basi levibus supra medium scaberulis, pani- 
cula elongata gracili laxiflora, bracteis filiformibus elongatis, ramis apicem versus floriferis, spiculis paucis 
magnis pedicellatis bracteolisque aristatis atro-purpureis, squamis paucis latis extimis aristatis spiculam 
superantibus, filamentis 4, stigmatibus 3-4 bifidis, nuce pallide brunnea.—Jorst. Prodr.
