obcuneatis, staminodiis falcatis acutis antice serratis.— Br. Prodr. 915. Bot. Mag. 3156. D. curvifolia, 
Lindl. Gen. et Sp. Orchid. 507. (Gunn, 343.) (Tas. CIV. B.) 
Has. Very abundant in pastures and loose forests throughout the Colony.—(Fl. Oct.) (v. v.) 
Distrıs. New South Wales and Victoria. 
A most common and extremely variable plant, which I vainly attempted, when in Tasmania, to find constant 
characters for; it varies in height from 4-12 inches, in the leaves being very narrow, linear-subulate or linear- 
lanceolate, in the scape being two- to ten-flowered, in the flowers being from ¿ to 1 inch across the petals (rarely 
more), and extremely in the narrowness of the petals and their spots, in the comparative size and shape of the seg- 
ments of the lip, in the length of the two lower linear sepals, which are generally much longer than the lip, and 
cross over one another, but are at other times free and straight, and a little in the form and toothing of the lateral 
lobes of the column. As a species it may be known by the stipitate broad petals, and equally three-lobed lip, 
which has two prominent ridges at the base.—PrATE CIV. B. Fig. 1 and 2, front and side view of lip; 3 and 4, 
front and back view of column :—all magnified. 
2. Diuris palustris (Lindl. Gen. et Sp. Orchid. 507) ; parvula, foliis 6-8 anguste linearibus scapo 
2-3-floro fere eguantibus, floribus aurantiacis purpureo-variegatis, sepalis inferioribus petalis lanceolatis 
duplo longioribus, labelli basi obscure bicarinati lobis egualibus intermedio subplicato, staminodiis falcatis 
acutis antice serratis. (Guan, 933.) 
Has. Marshy ground near Hobarton, Circular Head, etc., Backhouse, Gunn. Port Dalrymple, Pat- 
terson.—(Fl. Dec.) 
Disrris. Victoria and South Australia. 
A small species, rarely more than 4 inches high, with numerous narrow-linear, almost filiform radical leaves, 
shorter than the two- or three-flowered scape.— Peduncles 3-1 inch long. Flowers small, 3 inch across; the petals 
very dark-coloured, of a deep orange, almost obscured by dark purple-red blotches. Lower sepals longer than in 
D. maculata, and petals narrower. 
9. Diuris sulphurea (Br. Prodr. 316); foliis 2-3 anguste linearibus scapo 2-4-floro dimidio bre- 
vioribus, floribus aureis purpureo-maculatis, sepalis inferioribus petalis spathulato-lanceolatis longioribus, 
labelli basi ecarinati lobo intermedio lateralibus duplo triplo majore, staminodiis falcatis latere sublobatis 
acuminatis.—Lindl. Gen. et Sp. Orchid. 509. (Gunn, 342, 932.) (Tab. CIV. A.) 
Has. Common in many parts of the Colony.—(Fl. Nov.) (v. v.) 
Disrris. New South Wales, Victoria, and South Australia. 
A larger and handsomer plant than D. maculata, further easily recognized by the paler, less-blotched flowers, 
by the labellum not having two elevated ridges at its base, and by the middle lobe being larger, and generally more 
than twice as large as the lateral. The majority of my specimens are a foot to 18 inches high, and the flowers are 
1-14 inch across the petals; the upper sepal is trulliform, with a very short claw, and two spots on each side of the 
middle ; the two lower are linear, and vary from as long as to twice as long as the lip: they rarely cross one another ; 
the petals are golden-yellow, with a deep purple-brown claw, and the labellum golden-yellow, blunt, with a prominent 
mesial line corresponding with a canal on the lower surface, have two large blotches on each side of the middle 
lobe, one small transverse one across the middle nearer its base, and mottled or clouded lateral lobes ; these mark- 
ings are however variable in size and shape.—PraTE CIV. 4. Fig. 1, dorsal sepal; 2, petal; 3, lateral, and 4, 
front view of labellum; 5, front, and 6, back view of column :—all magnified. 
4. Diuris corymbosa (Lindl. Swan River Bot. n. 228) ; foliis 2-3 linearibus ensiformibusque scapo 
2-4-floro brevioribus, floribus flavo-purpureis, sepalis lateralibus petalis spathulatis subzequantibus, labelli 
lobis subzequalibus intermedio obcuneato basi ecarinato, staminodiis falcatis crenatis.— Lind/. Gen. et Sp. 
Orchid. 511. An P. aurea, Br. Prodr. 316? (Gunn, 342, anno 1835, 931.) (Tas. CV. B.)
