458 OBSERVATIONS ON PLANTS, 



long ; it shows the stamens of N. stellata, not of ffi. gigantea, 

 although Prof. Caspary recorded already, 1866 (Miq. Annal. Mus. 

 Lugd. Batav. n. 247), also a small-flowered variety of that species 

 from Queensland, which might readily be taken for N. tetragona, 

 but has different stamens, and differs also in some other respects. 

 The whole subject will soon be fully discussed in an essay on Sir 

 Will. Macgregor's latest Papuan plants, among which occurs also 

 a small-flowered Nymphaea. 



HlBBERTIA LEPIDOTA, R. BrOWll. 



Prince Regent's River. 



ROEPERIA CLEOMOIDES, F.V.M. 



Durack River, and between the Forrest and Drysdale Rivers. 

 Found also at Cambridge Gulf by Johnston and on the Leichhardt 

 River by Armit. 



Sprengel with remarkable definiteness makes his Roeperia super- 

 sede Ricinocarpus. Should, therefore, in publications from before 

 1817, his naming have become established, then the homonymous 

 capparideous genus might receive the name of Prof. Paul Falken- 

 berg, the present successor of Roeper in Rostock. Eichler in his 

 highly important Pflanzen-Diagramme, II. 208 and 211, fully also 

 sustains the generic validity of our Roeperia. 



Drosera Indica, Linne. 

 Durack River and Paradise Creek. 



Stem to 1J feet high. The petals of some of the specimens 

 rose-coloured and nearly half an inch long. 



Drosera petiolaris, R. Brown. 

 Paradise Creek. 



Byblis liniflora, Salisbury. 

 Durack River. 



Habitually resembling small forms of Drosera Indica. Traced 

 southward to near the Gascoyne River by Mr. H. S. King. 

 Petals not rarely denticulated.
