the tip. Anther broadly oblong, with an erect stout mucro.— This looks like a drawn-out state of T. Forsteri, 
growing in long grass or shade. Also a native of Australia and Tasmania. 
Ogs.—I have received from Mr. Colenso specimens of a Zhelymitra in acetic acid, resembling 7. Forsteri in all 
respects, except that the staminodia are subulate, sharply toothed, and not feathery; they are too soft and decayed 
for determination, as is often the case with specimens thus pickled.

Perianthium carnosum.  Sepalwm superius galeatum, lateralia sessilia, labello supposita; petala 
ascendentia ; Zabellum subunguiculatum, basi bicallosum. Anthera terminalis, persistens. Columna brevis, 
biaurita. Pollinia 4, apici stigmatis affixa.—Herbe terrestres ; floribus minimis, dense spicatis. 
An extensive Australian and Tasmanian genus, of which but one, and a highly variable species, inhabits New 
Zealand; it much resembles Prasophyllum Colensoi, but the flowers are smaller and not resupinate.— Root of one 
small round tuber. Stem 6 inches to 2 feet high, sheathed at the base. Leaf solitary, terete, tubular. Spike 
1-6 inches long, twenty- to eighty-flowered. Flowers very small, green, sessile, 3-1 inch long. Bract very short. 
Perianth minute, fleshy. Upper sepal broadly ovate, concave, hooded, two lower placed under the lip, broad, sub- 
acute; petals small, ascending, blunt. Zip oblong, crenate or crisped, blunt or obscurely bilobed, with two lumps 
at the base and one towards the tip on the disc. Column very short, with two broad lateral lobes. Anther ter- 
minal. (Name from puxpos, small, and. ovs, an ear.)

Gen. X. ACIANTHUS, Br. 
Sepala aristata, lateralia labello supposita, angustiora. Petala suberecta v. reflexa. Labellum dis- 
simile, porrectum, basi bicallosum. Columna semi-teres, elongata, arcuata. Anthera terminalis, opercu- 
laris. Pollinia 4, per paria coheerentia.—Herbe terrestres, tenella, sylvicole, l-foliate, pauciflora. 
A small genus of Australian and Tasmanian very delicate herbs, found in mossy places in deep woods. The 
New Zealand species has been found also in Lord Auckland’s Group, and is very closely allied to the Australian 
A. fornicatus, but differs in the lip being less glandular.—Zubers round, formed at the end of long thick fibres. 
Stems 1-3 inches high, with one broadly cordate, acute, deeply two-lobed leaf, 4-3 inch broad. Racemes of two to 
six green flowers. Bracts broad, acute. Ovarium oblong. Perianth 2 lines long. Sepals all aristate; upper 
broad; three-nerved ; lateral narrow, longer, one-nerved, toothed below the arista. Petals small, lanceolate, acute. 
Lip ovate-lanceolate, with two lumps at the base and a warted thickened apex. Column slender, curved, not winged. 
Anther terminal. (Name from arn, a point, and avos, a flower.) 
1. Acianthus Sinclairii, Hook. fil.; folio late cordato acuto profunde bilobo, racemis 9—6-floris, 
bracteis late ovatis acutis, sepalis aristatis supremo late oblongo 3-nervi, lateralibus lineari-elongatis infra 
aristam obligue 2-dentatis, labello ovato lanceolato basi bicalloso apice acuto verrucoso.
