250 ELORA OF NEW ZEALAND. | Orchidee. 
Anthera terminalis.—Herbe terrestres ; caule brevissimo ; folio solitario, membranaceo ; scapo brevi, unifloro, 
‚Fruetifero elongato ; floribus sordide purpureis. 
One of the most curious-looking genera of this remarkable Natural Order, similar to Corysanthes of Australia, 
to which it is closely allied.—Roots fibrous. Stems succulent, sheathed at the base, often appearing like a petiole, 
from the side of which the flower bursts. Leaf broad, sessile or petioled. Scape short, with one flower and bract, 
lengthened in fruit. Flowers lurid purple, conspicuous for the filiform slender petals and sepals. Upper sepat 
hooded, lateral filiform, placed under the lip, projecting horizontally. Pelals filiform, erect. Lip very concave, 
cordate at the base, broader than long, with incurved margins, and many veins, which, projecting beyond the 
truncate edge, give it a fringed appearance. Column short, curved, with a terminal, one-celled, two-lobed anther. 
Pollens four (according to Brown).—The species all reguire examination in a living state; those described appear 
remarkably distinct from one another, but more specimens are very much desired. (Name from vyua, a thread, and 
kepas, a horn.)

Has. Northern and Middle Islands; damp woods. East Coast and interior, Colenso. 
A smaller plant than N. macrantha, with proportionally still longer thread-like lateral sepals and petals. Leaf 
petiolate, 3 inch across, deeply cordato-reniform, trifid, rarely entire at the point; middle lobe acute. ` Peduncle 
shorter than the petiole, often much lengthened when in fruit. . Perianth 4 inch long; sepals 2 inches; petals half 
the length of the lateral sepals; upper sepals dilated and retuse at the point. Zip very large, of two parallel 
recurved lobes, and having two curved ears at the base; margins nearly entire. — Column very small.
