512 NEOTTE Æ—DIURIDÆ. 
petaloideo aucta. Anthera mutica, loculis approximatis. Pollinia 9, 
biloba. Herbe terrestres in Nova Hollandia orientali extra-tropica 
et Nova Zelandia indigene, Diurium habitu, sed bracteis herbaceis 
cymbiformibus et floribus clausis diversissime. 
1. Orruoceras strictum. R. Brown prodr. 317. 
O. bracteis ultra sepalum dorsale longe productis. 
Hab. in Australia ; prope Portum Jackson, R. Brown; raró inter Appin et 
Illawarram, necnon in agro sterili fruticoso ultra vallem Wellington oc- 
cidentem versus, Nov. Dec. 4. Cunningham. (hab. s. sp.) 
Of this singular plant I only possess the upper part of the inflorescence. 
Its lower bracts are an inch and half long, while it is not more than an 
inch to the point of the dorsal sepal. The closed up flowers look 
like a bird's head curved downwards between the two long ascending 
lateral sepals. 
2. OnrTHGocEnas Soiandri. 
O. bracteis ultra sepalum dorsale vix productis. 
Orthoceras strictum. 4. Cunn. Comp. Bot. Mag. 2. 376. 
Diuris Nove Zelandiz. Ach. Rich. ft. nov. zel. 163. t. 25. f. 1. 
Ophrys cornuta. Soland. MSS. 1769. 
Hab. in Nova Zelandia ; in insula septentrionali Banks et Solander, A.D. 
1769; in collibus inter filices, in sinu Insularum, ad Wangaroam, ali- 
bique, R. Cunningham. (hab. s. sp. comm. cel. Cunn.) 
That this is distinct from the New Holland species I entertain no 
-doubt ; its very short bracts and smaller and narrower flowers sufficiently 
attest that; but I am unfortunately destitute of the means of stating the 
differences between the species more precisely. The plant is called Ma- 
kuku by the N. Zealanders, not Makukia, as it would appear from Mr. 
Cunningham's notes, in my herbarium. 
CCXCIII PRASOPHYLLUM. 
Prasophyllum. Brown prodr. 1. 317. Endl. gen. no. 1581. 
Perianthium ringens. Sepala lateralia postica, distincta, v. basi cohe- 
rentia. Petala sepalis subzequalia. Labellum posticum, unguiculatum, 
adscendens, indivisum, ecalcaratum, sæpius laminà adnatá margine 
liberá auctum. Columna trifida, laciniis lateralibus membranaceis, 
integris bifidisque. Anthera mutica, mucronata aut rostrata, loculis 
approximatis.  Pollinia 2, biloba, apici stigmatico affixa. Herbe 
terrestres Australasice ; bulbis indivisis. Caulis monophyllus, basi vagt- 
nis aliquot brevibus instructus. Folium teres, fistulosum, quandoque 
abbreviatum, vagina longissimá. Flores spicati. 
The species of this genus are most difficult to determine in a dried 
state, and require a careful revision by some botanist who can compare 
them when alive, and ascertain the limits of their variation. Mr. Gunn 
regards them as even more numerous than I do, but it is to be feared that 
some of the supposed species are only varicties.
