14 FLORA OF TASMANIA. | Orchidee. 
Has. Sandy soil: near Hobarton, J. D. H.; Cheshunt?, Archer.—(Fl. Sept.) 
Root and scape as in the other species of this section. Bract placed below and rather distant from the spike. 
Spike 3-1 inch long, eight- to twelve-flowered. Flowers minute, short, curved, the perianth pointing downwards. 
Sepals and petals acuminate, with subulate points. Staminodia with incurved, subulate points, which, with the 
deflexed flowers, distinguish this species well from all its allies.—PrATE CXIII. 4. Fig. 1, flower; 2, side view of 
column and labellum ; 3, labellum ; 4, front view of column :—all magnified. 
12. Prasophyllum Archeri (Hook. fil.) ; scapo gracillimo apicem versus bractea longe acuminata 
instructo, spica brevi pauciflora, floribus horizontalibus flavo-rubris, sepalis lateralibus basi connatis dorsali 
late ovato acuminato longioribus, petalis ovato-lanceolatis acuminatis, labello unguiculato marginibus fim- 
briato-laceris, lamella adnata simplici crassa definita, staminodiis bilobis lobo anteriore subulato fimbriato 
carnosulo posteriore breviore truncato membranaceo, anthera rostro elongato. (Tas. CXIII. B.) 
Has. Light soil near Cheshunt, Archer. 
A very distinct species, of the same habit and general appearance as P. brachystachyum, but more slender, 
with smaller reddish-yellow flowers, fimbriated membranous margins to the lip, which bears a very prominent, 
thick, cellular, undivided, adnate lamella, grooved down the middle, and ¡very different staminodia: these are 
broad, and unequally two-lobed, the outer or lower lobe is red, subulate-lanceolate, curved, cellular and papillose, 
with fimbriated edges; the inner or upper is shorter, broader, truncate, transparent, white, and naked.— Anther 
with a long rostrum.—Prarg CXIII. B. Fig. 1, front, and 2, side views of flower; 3, column and labellum ; 
4, front of column; 5, front, and 6, side views of pollen :—all magnified. 
13. Prasophyllum nudum (Nob. in Fl. N. Zeal. i. 242); scapo aphyllo gracili apicem versus 
1-bracteato, spica multiflora, floribus suberectis breve pedicellatis minute bracteolatis atro-purpureis, sepalis 
lateralibus basi connatis subsaccatis dorsali ovato-acuminato longioribus, petalis ovato-lanceolatis acuminatis, 
labello oblongo-lanceolato unguiculato, lamina basi biauriculata marginibus fimbriatis, lamellis adnatis 2 
parallelis discretis, staminodiis bilobis lobo anteriore subulato subfimbriato posteriore obtuso latiore, anthera 
longiuscule rostrata. (Tas. CXIII. C.) 
Has. Collected by Gunn, but I do not know where. 
DisrarB. New Zealand. 
Very variable in size, 3-10 inches high, always slender, with a leafless, one-bracteate scape, and rather long 
spikes of eleven to thirty ascending, minute flowers, smaller than in any of the preceding of this section. It is 
very nearly allied to P. Archeri, but differs in the two distinct, parallel lamelle on the labellum, and the shorter, 
less fimbriated, anticous lobe of the staminodia.—Prarg OXIII. C. Fig. l, side, and. 2, front views of flower ; 8, 
labellum :—all magnified. 
Gen. III. CALOCHILUS, Br. 
Perianthium ringens. Sepala patentia, libera, æqualia ; lateralia labello supposita. Petala minora, 
erecta. Labellum anticum, sessile, simplex, liberum, acuminatum, disco marginibusque barbatum. Columna 
teres, carnosa, cucullata, rostello acuto. Anthera stigmate parallela, persistens, columnæ inclusa, mucro- 
nata. Pollinia 2, sulcata.—Herbæ glabre, bulbis ¿ndivisis nudis ; foliis paucis radicalibus canaliculatis, 
caulinis semi-vaginantibus ; floribus paucis, raris, spicatis racemosisve, majusculis, rufis albisve. 
The few known plants of this genus are very beautiful, and all Australian; they are easily recognized by 
the red-brown (rarely yellowish or white) flowers, with an ovate-lanceolate labellum, covered with a copious, pendu- 
lous beard of delicate filaments.—Root an undivided bulb, above which are very thick, spreading, eylindrical root- 
lets; stem 12-18 inches high, with one or a very few narrow radical leaves, and some sheathing ones on the scape. 
Flowers few, large, racemose or spicate, with three nearly equal, lanceolate sepals, of which two are placed under
