As a rule, the calli on the labellum agree with the description given above; but 
occasionally the number is reduced to 6, and I have seen as many as 12. The flowers 
are sometimes nearly altogether purple.

2. ©. formieifera Fitzgerald Austral. Orch. 1 (1877) pt. 3. — Slender, 
delicate, 2-3in. high. Leaves 2, close together, sessile, spreading, 1-2 in. 
long, linear-oblong or oblong-lanceolate, obtuse, thin and membranous, 
margins often undulate when fresh; veins parallel, connected by trans- 
verse veinlets. Scape 2—3in. high, 1-flowered; bract near the top, 
sheathing. Flower about 4in. long. Upper sepal linear-spathulate, erect, 
acuminate; lateral about the same length, lear, acuminate. Petals linear- 
lanceolate, abruptly deflexed, about as long as the sepals. Lip horizontal 
or ascending, contracted below into a long and narrow claw, above 
suddenly expanded into a short and broad spoon-shaped or rhomboid 
lamina, the tip of which is usually reflexed ; disc with numerous call, the 
largest of which is placed at the base, and projects from it, with a kind of 
double head, towards the column; in front of this is a large flat heart- 
shaped gland, and rows of smaller calli reach the apex of the lip. Column 
arched forward, broadly winged.—Cheesem. in Trans. N.Z. Inst. xxxi

Norta Istanp: Auckland — Kaitaia (Mongonui County), R. H. Matthews / 
Septem ber—Octo ber. 
A very remarkable little plant, previously known only from eastern Australia. 
Mr. Matthews’s specimens agree in all respects with Mr. Fitzgerald’s beautiful plate. 
Very rare and local, and up to the present time very few specimens have been found.

18. ADENOCHILUS Hook. f. a4t. St 
Slender terrestrial herbs. Leaf solitary, placed near the middle of the 
stem, ovate. Peduncle slender, 1-flowered, with 1 or 2 sheathing bracts 
between the flower and the leaf, the upper of which sometimes bears in its 
axil the minute rudiment of a second flower. Flower small. Upper sepal 
erect, incurved, concave or almost galeate ; lateral lanceolate, placed under 
the lip. Petals linear-lanceolate, almost equalling the sepals. Lip shortly 
clawed on to the base of the column, 3-lobed; lateral lobes large, erect ; 
middle lobe smaller, caudate, reflexed ; disc and middle lobe with several 
rows of small stalked calli. Column slender, curved, winged; wings pro- 
duced upwards into 2 toothed lobes. Stigma prominent, placed just under 
the rostellum. Anther terminal, erect, 2-celled ; pollinia 4 in each cell, 
granular. 
The genus is limited to two species: one endemic in New Zealand, the other 
(A. Nortoni Fitzgerald) in Australia. It is closelv allied to both Caladenia and 
Chiloglottis, differing from the former in the wing of the column extending behind the 
anther, and from the latter in the solitary leaf and glandular-pubescent perianth.
