slender and more elongated calyx-tube ; narrower, thinner, more pointed 

 aud conspicuously venulated corolla-lobes, in longer anthers ; the fruit of 

 R. Moorei may also be difterent, but the Stigmas are likewise severed. 

 Also allied to R. patuhr. 



The dissepiment of the ovulary or fruit could not be traced from the 

 speciment available ; should it not pass through the whole width of the 

 cavity, then it will become necessary to transfer this plant to Gardenia. 

 In some respects it reminds of Coffea Benghalensis, the Stigmas of which 

 are elliptic also. 



PrasophyUum Dixoni, 



Comparatively dwarf, leafless at the time of flowering, except a 

 rudimentary leaf close to the spike ; tuber roundish, somewhat compressed ; 

 fiovvers in the spike few, very small, closely together, pale yellowish- 

 green, recurved ; bracts almost semi-lanceolar, acuminate, somewhat shorter 

 than the calyx-tube ; unpaired calyx-lobe ovate-lanceolar, concave, as long 

 as the paired petals and hardly by about one-third shorter than the 

 labellum and paired calyx-lobes, the Jatter lanceolar, connate near their 

 broadish rather bulging bases ; paired petals ovate-lanceolar, finely shorth- 

 pointed ; labellum suddenly short- aud broad-stipitate, ovate-cuneate, liardly 

 apiculate, fringeless though imperfectly and faintly ciliolar-denticulated 

 toward the summit and there somewhat rededged, towards the base 

 slightly two-ridged ; lobes of the gynostemium very short, glabrous bifid ; 

 fruit obliquely cylindric-ellipsoid.

As yet only two specimens found, and so far as this material allows 

 to judge not really indentifiable with any described species. According 

 however to figures in Mr. Robt. Fitzgerald's splendid work on „Australian 

 Orchids," the plant just now discovered here as one of our earliest 

 flowering in the season, differs from P. viride in the stem being more 

 slender, the paired calyx-lobes less bulging, in the labellum rather truncate 

 than distinctly bilobed at the base, the stipes shorter, also in throughout 

 greenish colour of all floral parts ; in this latter respect the new Victorian 

 plant is still more unlike P. ansatum, although as regards floral structure 

 it is evidently a near ally ; but the apex of the paired calyx-lobes and 

 petals is devoid of a glandule, whilst the labellum is not callously 

 thickened towards the summit, but towards the base, nor is it glandulär 

 enlarged at the edge near the middle. Our plant flowers in April and 

 May, so that at such time it may easily elude detection.
