3. Prasophyllum brevilabre (Hook. fil.); folio scapo gracili »quilongo, floribus laxe spicatis, 
ovariis pedicellatis turgidis, bracteis minimis pedicellos subeeguantibus, sepalis subacutis lateralibus cuneatis 
petalisque obtusis, labello elongato basi subsaccato medio refracto, lamella adnata crassiuscula marginibus 
undulatis, staminodiis lineari-oblongis falcatis recurvis obtusis.— P. lutescens, var. 8. brevilabris, Zindl.

But for the remarkable difference in the ovary and bracts of this species, I should not have ventured to have 
separated it from P. lutescens. In this however the ovaries are shorter, very turgid, distinctly pedicelled, and the 
minute bracts are hardly longer than the pedicels. The whole plant is also smaller, has fewer and more distant 
flowers, the sepals and petals are blunter, and the labellum is sharply doubled back on itself at about the middle. 
Gunn remarks that the labellum is shorter, as well as more acutely reflexed : the latter character I observe to be the 
case, but I think the shortness is the resulting appearance.—PLATE CX. 4. Fig. 1, flower; 2, labellum; 3, side 
view of labellum and column; 4, front view of column; 5 pollen :—all magnified. 
4. Prasophyllum flayum (Br. Prodr. 318); caule robusto folioque brevissimo atro-purpureo, spica 
multiflora, floribus luride viridibus, bracteis acuminatis ovariis cylindraceis brevioribus, sepalis dorsalibus 
connatis lateralibus petalisque subacutis, labello basi non saccato breviusculo recto v. vix recurvo apice 
attenuato marginibus undulatis, lamella adnata crassiuscula, staminodiis brevibus obtusiusculis. (Tas.

I have examined two specimens of this plant, which varies from 10-18 inches high, and is more or less 
robust, and when dry deep purplish-black. It is very similar to P. australe, but may be known from it by the very 
short leaf, and from others by the slender ovaries, with acute bracts about half their length, the cuneate lateral 
sepals, short, nearly straight labellum, not saccate at the base, with undulate margins, and short, small staminodia.—

$ 2. Lateral sepals free (except in P. alpinum and rostratum). Labellum not suddenly contracted at the apex. 
5. Prasophyllum patens (Br. Prodr. 318); pallide viride, folio caulem elatum æquante v. supe- 
rante, floribus laxe spicatis majusculis patulis, ovariis turgidis pedicellatis, bracteis parvis obtusis pedi- 
cellos vix superantibus, sepalis subacutis lateralibus liberis apice raro dentatis, labelli late ovato-lanceolati 
reflexi marginibus late undulatis, lamella adnata crassa bilamellata apice evanescente, staminodiis suberectis 
faleatis apice truncatis integris emarginatisve.—P. truncatum, Lindl. l.c. 513. (Gunn, 352, 926, 927.)

Has. Abundant in moist ground throughout the Island.—(Fl. Nov., Dec.) (v. v.) 
Distris. New South Wales and Victoria. 
After a laborious examination of very many specimens, I find myself quite unable to distinguish all Gunn’s 
specimens of P. truncatum from P. patens. Archer however, in his notes and drawings, distinguishes two species 
by the form of the adnate lamella on the surface of the labellum, that of P. patens gradually subsiding into the sub- 
stance of the labellum, whilst that of P. truncatum ends abruptly at the flexure; the sepals of P. truncatum are 
further more uniformly notched near the apex.—The general form of the staminodia, which are broadly oblong and 
faleate in all the specimens, is very much the same, but the apex varies extremely, being truncate, rounded, or sub- 
acute, entire, erose, or notched.—Root-tubers bilobed (always?). Scape 6-18 inches high, with one leaf as long as
