12 FLORA OF TASMANIA. [ Orchidee. 
itself, or longer. Spike loose, appearing distichous in the dried specimens, many-flowered. Flowers often sweet- 
scented, but not constantly so, pale-whitish or greenish-yellow, pedicelled. Bracts very small, blunt, scarcely longer 
than the pedicels. Ovaries turgid. Sepals acute, the lateral free, never or seldom notched near the tip. Petals 
linear, blunt, sometimes more or less undulate. Zadellum recurved, with a distinct, bilobed, rather fleshy lamella, 
which sinks gradually into the substance of the labellum at its termination ; margins very undulate.—PrATE CXI.

6. Prasophyllum truncatum (Lindl. Gen. et Sp. Orchid. 513); pallide virescens, folio caulem 
elongatum sequante v. superante, spica multiflora, floribus majusculis patulis pedicellatis, bractea parva obtusa 
pedicello zequilonga, sepalis subacutis lateralibus liberis apice sepius dentatis, petalis planis undulatisve

I am quite unable to distinguish all states of this, when dry, from P. patens, either by the form and notch- 
ing of the apex of the staminodia, or by any other character, except the form of the lamella on the labellum : 
this I find from Archer's drawings to be abruptly terminated at the flexure of the labellum with a strong, raised, 
transverse edge, whilst that of P. patens gradually sinks into the nerves of the labellum. In some states the petals 
are much undulated, and in these the lateral sepals are more freguently notched towards the apex.—PLATE CIX. B.

7. Prasophyllum alpinum (Br. Prodr. 318) ; virescens, folio caulem gracilem superante, ovariis tur- 
gidis pedicellatis, bracteis pedicellos eequantibus brevibus rotundatis, floribus parvis, sepalis acutis lateralibus 
liberis approximatis v. basi connatis, labello ovato-lanceolato ultra medium repente angustato pubescente 
v. glabrato marginibus vix undulatis crassiusculis, lamella adnata vix definita, staminodiis brevibus obtusis 
hine emarginatis.—Lindl. L c. 515. (Gunn, 929.) (Tap, CXIL. A.) 
Haz. Alpine and subalpine localities: Circular Head, Gunn ; Mount Wellington, Oldfield ; Western 
Mountains, Archer.—(Fl. Nov.-J an.) 
 DisrmrB. Australian Alps, Mueller, 
Generally a small, pale green species, with the leaf longer than the scape, but very variable in size, and some- 
times 18-20 inches high. Flowers loosely spiked, not so patent as in P. patens, and smaller. Ovaries turgid, 
pedicelled ; pedicels with short, blunt bracts. Lateral sepals free, or rarely united at the base or to the middle, 
sometimes notched near the apex. Lip short, fleshy, with thick, hardly undulate margins, and a thickened, but not 
defined disc, often pubescent, ovate at the base, suddenly contracted beyond the middle, not strongly recurved.—It 
is difficult to define this species from some states of p. patens by words, but it is a Very distinct plant, and when 
fresh has a strong smell of Hyacinths.—Prarg CXII. 4. Fig. 1, side, and 2, front view of flower; 3, back,

8. Prasophyllum fuscum (Br. Prodr, 318); fusco-viride rarius pallidum, folio scapo gracili 
quante v. longiore, spica multiflora, floribus pedicellatis, bracteis parvis pedicellos 
P. rostratum, Lindl. Gen. ef Sp. Orch. 516. (Gunn, 353.) (Tas. CXIL B.)
