DESCRIPTIONS OF SOME NEW AUSTRALIAN PLANTS. 

 By Baron von Mueller, K.C.M.G., M. & Ph.D., F.R.S., &c. 



Oldknlandia Psychotrioides. 



Leaves rather large, from ovate to elongate lanceolar, somewhat 

 acuminate, almost membranous, narrowed into a short stalk, 

 beneath slightly paler and along the thin venules beset with hair- 

 lets, above glabrous ; stipules deltoid, short-pointed, fugacious ; 

 cymes in a terminal divergently branched ; panicles bearing densely 

 short appressed brownish-grey hairlets; flowers quite small, pentam- 

 erous ; bracts minute, narrow-semilanceolar ; calyx-lobes roundish- 

 deltoid, very short ; tube of the corolla almost entirely enclosed, 

 inside glabrous, turgid, lobes membranous, venulous, about as 

 long as the tube ; anthers almost sessile, ovate-ellipsoid, broadest 

 towards the base, and there slightly bilobed, their apex minutely 

 bidenticular, their dehiscence introrse ; style never much elon- 

 gated ; stigmas very short ; epigynous disk beset with minute 

 hairlets ; fruit small, only with its quadrivalvular summit emerg- 

 ing, ovate-globular, slightly compressed ; placentaries inserted 

 about the middle of the dissepiment; seeds numerous, very 

 minute, shining brown, somewhat oblique-ovate^ angular, reticular- 

 foveolate. On the Russell River ; W. Sayers. 



Among species with leaves of similar size and form O. aciitan- 

 gula, O. stylosa, O. viscida, O pruinosa, O. Lessertiana, O. 

 purpiirescens, and 0. cymosa differ in almost complete absence of 

 general vestiture and in a corolla with well emerging tube to some 

 extent beset with hairlets inside, irrespective of some other charac- 

 teristics not common to these seven species. O. arbo?'ea has an 

 almost tubeless somewhat rigid corolla ; O. hirsutissima fringed 

 stipules, axillary inflorescence, and elongated filaments ; O. 

 Leschenaultiana leaves rounded at the base, and also conspicu- 

 ously paler beneath, denser inflorescence, fewer and larger seeds. 

 Our new plant, moreover, diverges from most of its congeners in 

 the five-lob'^d calyx, and tlie correspondingly five-cleft corolla and
