8 FLORA OF TASMANIA. [ Orchidee. 
Has. Common in the northern parts of the Colony, as at Circular Head, Emu Bay, Georgetown, ete., 
Gunn, Archer.— (Yl. Sept., Oct.) 
Distri. New South Wales, Victoria, and Swan River. 
Similar in habitat and general characters to the preceding species, but of a duller colour.—Flowers of the same 
size as those of J). sulphurea, or rather larger, sometimes more than 13 inch across the petals; upper sepal of a 
dirty yellow, suffused with dull-red, broadly ovate. Petals dull yellow, faintly clouded with red. Labellum with 
three nearly equal lobes, or with the middle one rather the largest, and obcuneate, rounded, truncate or emarginate 
at the tip, without any prominent ridge or keel.—Prarg CV. B. Fig. 1, labellum :—magmified. 
5. Diuris pedunculata (Br. Prodr. 316); foliis 3-5 linearibus scapo 1-4-floro brevioribus, floribus 
pallidis, perianthio connivente, sepalis lateralibus labello appressis porrectis, petalis elliptico-lanceolatis, 
labelli lobis lateralibus rarius crenatis intermedio trullaeformi acuta medio carina duplici pubescente instructo. 
—D. lanceolata, Lindl. Gen. et Sp. Orchid. 508. (Gunn, 609, 934.) (Tas. CV. 4.) 
Has. Abundant in moist places near Hobarton, and other parts of the Island.— (Fl. Oct.) (v. v.) 
Disrris. New South Wales, Victoria, and South Australia. 
A very different species from any of the foregoing, but extremely variable. It is at once recognized by the 
pale-yellow horizontal flowers, whose perianth appears compressed from above, and not spreading, and the labellum 
has a double downy ridge down the centre: it is one of the earliest spring flowers.— Very variable in height, 4—10 
inches. Zeaves rather numerous, very slender. Flowers generally one or two, but sometimes four, on long pedun- 
cles, 3-13 inch long, including the ovary; upper sepal short, narrow, oblong or broadly ovate, pointing forwards, 
and parallel to the lip ; lateral sepals placed close below the lip, linear, straight or curved, as long or longer than 
the lip. Petals pointing forward, narrow or broad, elliptical, about as long as the lip, with short purplish claws. 
Lip with two small erenate lateral lobes, like auricles, at the base of the larger lobe, which is plane, triangular- 
ovate, acute, points forwards, and is very variable in length.—PraTE CV. 4. Fig. 1, dorsal sepal; 2, petal; 3, 
labellum; 4, column :—all magnified. 
Gen. TII. CRYPTOSTYLIS, Br. E 
Sepala patentia, lineari-lanceolata, acuminata. Petala consimilia sed minora. Zabellum magnum, 
posticum, sessile, indivisum ; basi concava, columnam brevissimam occultante. Stigma ovatum. 
margo membranacea, lacera. Anthera stigmati parallela, obtusa, bilocularis. 
Herbs; bulbis teretibus, fascieulatis, subarticulatis ; folio radicali petiolato, lineari-lanceolato, coriaceo, 
reticulato ; floribus scapum vaginatum terminantibus, spicatis, sordide rufis, majusculis. 
Columna 
Pollinia 4, pulverea.— 
The species of this genus, of which three are described, are all Australian herbs, but are so closely allied to 
some East Indian and Malayan Island plants (Zosterostylis, Bl.), 
brought into the same genus.— Flowers rather large, dusky 
strongly net-veined when dry. Roots fascicled, of thick, 
herb, 10-24 inches high, with one rather coriaceous, 
erect, rather stout, with a few distant, short, sheathing 
of an inch broad. Ovary curved, slender, 
dirty yellow-green, almost an inch long. 
(2. e. posticous), pointing forward, its face looking downward broadly-obovate 
three medial ridges terminating in a double tubercle towards the apex, dirty reddish-brown. Column very short, 
hidden in the cucullate base of the lip, its margins expanded, membranous, and torn. (Name from KPUTTOS, CON- 
cealed, and oruXos, a column.) 
flat, radical, linear-lanceolate leaf on a long petiole. Scape 
bracts. Flowers three to eight, rather distant, sessile, upwards 
3 inch long, about twice as long as the bracts. Sepals narrow-linear, 
colour. Zip superior 
, oblong, blunt, margins recurved, with
