THE TASMANIAN FLORA. 207 



Side segments bent back. Labellum narrow, covered. 



with glands 1. C. diphylla.. 



Side segments sub-erect. Labellum broad, with few 



glands 2. C.gunnii. 



1. C. DIPHYLLA, iR. Br. Leaves 2, at the base of the stem, narrow-oblong, 

 «,cute, naiTowed into a short stalk, 1-2 inches long. Stem usually 3 or 4 inches 

 high, much elongating after flowering, with a sheathing bract a little below the 

 flower. Flower solitary, green and brown ; upper segment ei'ect, narrow, f, inch 

 long, lanceolate, acutely pointed ; lowest pair narrow, linear, curved ; side pair 

 linear-lanceolate, bent downwards and backwards. Labellum narrow at the 

 base, broad near the end, acute, covered, except on the broader portion, by thick 

 glands in the centre and slender ones at the side. Column slender, the wing 

 narrow above, extended at the side of the anther, vanishing below. 



Yery common, but not flowering freely ; often overlooked accordingly ; also in 

 Queensland, New South Wales, and Victoria. Fl. Sept.-Mar. 



2. C. GUNNii, Lindl. Leaves as in' the last. Stem shdrt, usually about 1 inch 

 till after flowering, the bract subtending the flower. Flower solitary, green and 

 brown ; upper segment broadly spathulate, acute, about 1 inch long ; lower pair 

 linear, bent forward ; side pair lanceolate, sub-erect. Labellum broadly cordate, 

 ^-f inch long, bearing few large black glands in the middle. Column bent 

 forwards, wing broad above and extended "behind the anther, vanishing below. 



Very common. It occurs also in Victoria and New South Wales. Fl. 

 Oct.-Jan. 



23. GLOSSODIA. 



Perianth-segments nearly equal, spreading. Labellum entire, without fimbriae 

 ■or glands, but with 1 or 2 free or nearly free basal appendages. Column erect 

 ■or nearly so, broadly winged, especially near the apex. Anther valvular. Stigma 

 peltate close below the anther. 



A small genus, confined to Australia ; only distinct from Caladenia by the 

 absence of glands from the labellum, and the peculiar appendage. 



G. MAJOR, R. Br. Leaf and stem delicately hairy. Leaf oblong, 1-2 inches 

 long, solitary at the base of the stem. Stem slender, about 9 inches long, with a 

 small bract below the centre. Flower usually solitary, blue to white. Perianth- 

 segments about I inch long, broadly lanceolate. Labellum about 3 lines long, 

 concave-convex, densely covered with minute papillose pubescence ; the basal 

 ^.ppendage solitary, yellow, about 1 line long, filiform, with a broad head. 

 Column 3 lines long. 



Very common. It occurs also in Queensland, New South Wales, Victoria, and 

 South Australia. Fl. Oct. 



Oedee TjXXVI.—BURMANNIACE^. 



Flowers regular. Perianth superior, tubular, 6-lobed, or rarely reduced to 3. 

 Stamens 3 or 6, inserted in the perianth-tube. Ovary inferior, 3-celled or 

 1-celled with 3 parietal placentas. Ovules numerous. Style single. Stigma 

 •3-branched. Fruit capsular. Seeds minute. 



A tropical order of herbs. Many genera have become parasitic or saprophytic. 



THISMIA. 

 Perianth campanulate, 6-lobed. Stamens 6, included. Ovary 1-celled, with 

 3 parietal placentas. 



A small genus, hitherto confined to the tropics. There are several small 

 genera closely allied. The Tasmanian plant is distinct in detail from
