Orchidee.) FLORA OF TASMANIA. 27 
tubers, and one sessile, sheathing, radical leaf. Flowers glandular, solitary or few, of all colours, large or small, some- 
times with very long, slender sepals and petals, and commonly called Butterfly-plants in Tasmania. Dorsal sepal 
generally concave, pointing forwards; lateral placed beneath the labellum. Petals erect or spreading. Zabellum 
clawed, cucullate, with incurved, membranous, often fimbriate margins, entire or three-lobed, generally much con- 
tracted beyond the middle, its disc with two or more rows of pedicelled glands. Column with membranous margins. 
(Name from kados, beautiful, and av, a gland ; in allusion to the glandular labellum.)

Disrris. Victoria to Swan River. 
A span to a foot high, covered with glandular pubescence.— Leaf very variable in size and form, 2-5 inches 
long, ovate-lanceolate to linear-oblong. Flowers one or two, rose-coloured, distinguished at once by the linear, 
erect, dark-purple petals. Odour very sweet, of hyacinths.—PrATE CXXI. 4. Fig. 1, side, 2, back, and 3, front

$ 2. CALONEMA (Lindl.).—Sepals and petals much elongated and caudate at the apex. Labellum fimbriated. 
Leaves slender in the Tasmanian species. 
2. Caladenia filamentosa (Br. Prodr. 324, non Lindl.) ; molliter patentim pilosa, sepalis petalis- 
que sequalibus longissime filiformibus puberulis atro-rufis, labello apice angustato elongato revoluto nudo 
marginibus crenulatis, disco biseriatim glanduloso, columna basi ecallosa apice biauriculata. (Tam. CXXI. 
Has. Forests: Cheshunt and Georgetown, Archer.—(Fl. Dec.) 
DisrRrB. New South Wales, Victoria, and South Australia. 
Archer's specimens of this fine species are the only Tasmanian ones I have seen; they are about a span long, 
and covered with long, patent, soft hairs. Flowers of a dark reddish-brown colour, 13-2 inches broad; the sepals 
and petals long-linear, but not thickened at the apex. Lip with a rather long, slender, revolute apex, slightly cre- 
nulate, with two short series of glands on the disc. Column auriculate at the apex.—PrATE CXXI. B. Fig. 1, 
column and labellum ; 2 and 3, labellum ; 4, column :—all magnified. 
8. Caladenia dilatata (Br. Prodr. 325) ; molliter patentim villosa, floribus pallidis, sepalis longe 
filiformibus apice interdum dilatatis vix puberulis, petalis brevioribus anguste linearibus, labello medio 
dilatato profunde pectinatim lacero dein abrupte angustato crenulato, glandulis disci confertim 4-seriatis, 
columna basi bicallosa apicem versus dilatata.—C. filamentosa, Lindi. Gen. et Sp. Orch. 421. C. tentacu- 
lata, Schlecht. (Gunn, 910.) (Tas. CXXII. B.) 
Has. Sandy soil: Circular Head, Gunn; forest lands near Cheshunt, Arc4er.—(Fl. Dec.) 
Disrris. South Australia, Victoria. 
A very elegant species, more villous than C. filamentosa, and with paler flowers, easily recognized by the sepals 
being linear-oblong for half their length, and then filiform, much longer than the petals, and being often somewhat 
dilated towards the tips; further also by the labellum being very broad at the middle, its margins there pectinate, 
and suddenly contracting to a narrow, crenulate, recurved apex; also by the four rows of long, purple glands on 
the deep-purple lip, and by the winged, but not auriculate, upper one-third of the column.—Pıarz CXXII. B.
