176 THE VICTORIAN NATURALIST. 



i inch. Lower expansion of the corolla %—}% inch long. Fruit 

 not yet obtained. 



This delicate and evidently rare species is dedicated to Dr. F. 

 Kamienski, professor in the University of Odessa, who was the first 

 to furnish a complete morphologic account of a terrestrial 

 Utricularia (the Australian U. lateriflora), who elaborated the 

 Lentibularinae for Englers and Prantl's " Pfianzen-Familien," who 

 travelled as far as south-eastern Asia for the study of this order of 

 plants, and who is now engaged on the monographic elucidation 

 of the species from all parts of the globe. 



U. compressa may possibly be represented by this plant ; but 

 R. Brown's notes, probably from Solander's manuscripts, are so 

 extremely brief as to admit of no safe identification, and speci- 

 mens of the particular plant from Cook's first expeditions exist 

 nowhere now. 



Utricularia Holtzei. 



Polypompholyx Holtzei, F. v. M. coll. Dwarf; pitchers few or 

 undeveloped ; stem capillulary-thin, usually one-flowered ; bracts 

 and bracteoles extremely minute, rather acute, basifixed ; pedicels 

 slightly thicker than the stem, shorter than the flower ; sepals 

 minute, blunt ; corolla small, cream-coloured, its lower expansion 

 deeply cleft into five lobes, all of these narrowly elliptic-cuneate, 

 rounded-blunt or somewhat truncate, the two outer considerably 

 shorter than the others, and but slightly exceeding the narrow 

 blunt or at the summit denticulated upper portion of the corolla ; 

 basal protrusion several times shorter than the long lobes, blunt, 

 proportionately turgid. 



Near the Adelaide-River ; M. and N. Holtz. 



Height 1^2-2 inches. Corolla %-Yz inch long. Fruit as yet 

 unknown. Root very short, fasciculate-capillular ; but some 

 specimens placed with this plant show a tender flexuous rhizome 

 elongated to several inches, minutely ramified, which really seems 

 to belong as a nutritive organ to this species. The aspect of the 

 plant is very much that of Polypompholyx tenella, particularly 

 on account of the fissurated lower expansion of the corolla, and 

 leaves will doubtless yet occasionally be found to.be formed as 

 well by this delicate plantlet. 



Messrs. Holtze further detected on the Adelaide-River also U. 

 albiflora or a closely allied species ; it agrees with the brief 

 definitions given by R. Brown and by Bentham for Sir Joseph 

 Banks's plant, except that the lower expansion of the corolla is 

 produced into five almost semi-lanceolar divergent lobes ; there- 

 fore the Holtzean plant might be distinguished as a variety or 

 possibly as a species by the designation quinquedentata. Its 

 extreme tenuity is that of U. capilliflora ; the corolla in drying 

 assumes a slightly yellow hue ; the minute fruit is nearly globular; 

 the seeds are extraordinary small, ellipsoid, and when ripe outside 

 dark-brown.
