One of the most curious-looking genera of this remarkable Natural Order, similar to Corymntbes of Austraha,
to which It IS closely allied.-Aoofs fibrous. Stem succulent, sheathed at the base, often appearing like a petiole
from the side of which the flower bursts. Xra/broad, sessile or petioled. Scape short, with one flower aud bract’
Jengthened m fruit. Mowers lurid purple, conspicuous for the filiform slender petals and sepals. Upper sepal
hooded, lateral iiUforra. placed under the lip, projecting horizontally. Fetals filiform, erect. Lip very concave,
cordate at the base, broader thau long, with incurved margins, and many veins, which, projecting beyond tliJ
trúncate edge, give it a fringed appearance. Column short, cm-ved, with a terminal, one-celled, two-lobed anther.
0 US four Caccordmg to Brown).—The species all require esamiuatiou in a Uviug state; those described appear
remarkably distmct from one another, but more specimens are very much desired. (Name from »7^«, « thread, and
Kfpas, a horn.)

H ab. Northern Island. Clay banks. Manawatu, Colenso.
I regret not having expanded flowers of this cm-ious little plant ; those I have in bud resemble JV. oblonga iu size
and form of the pieces of the perianth. S im slender, 1-2 iuehes loug. Leaf orbicular, cordate, acummate or
apieulate, | inch broad. The flower rises fi-om between the lobes at the base of the leaf in my specimens, but this
may uot he a constant character. I have leaves of this or a very similar plant from Lord Auckland’s Group.

This resembles N. triloba very closely, but the leaf is shortly petiolate, and the labellum of a very different
form, being trowel-shaped, much recurved, with a retuse truncate apex. The leG also is longer aud ovate.
Ob s . I have several species or varieties of this genus, from the Middle and Southern Islauds, gathered by Dr.
Lyall, and from Lord Auckland’s Group; hut they are not in a fit state for determination.

A curious genus, belonging to a smaU section of the family, of wliich very few species are known ; they inhabit
dark woods, one in New Zealand, another in Tasmania and Australia. A very few closely aUied plants occur in
Java, the Indian mountains, and iu Siberia; all are leafless parasites, and are of a uniform pale brown colour. G.
Cuminghamii has a root as thick as the fore-fiuger, sometimes eighteen inches long, full of starch, and eaten by the
natives.—®«» 1-2 feet high, stout, bearing here and there semi-amplexicaul, obtuse, membranous, alternate or
opposite and connate bracts. Raceme 6-10 inches long. Mowers 20-50, shortly pedicellate, pendulous, with short
scarious bi-aots. Perianth tubulai-, split half-way down the back, gibbous or swollen below, five-toothed, -i inch long,
fleshy. Lip free, clawed ; claw winged ; lamina linear-obloug, membranous, waved, with two thick ridges down the
middle. Column very short. Anther two-cellccl, deciduous. Pollens two (or four in cohering pairs), of very large
grains, Sligma a glandular surface in front of the base of the column, communicating by a cavity with the ovarium.
