extrernely minute, rather acute, basifixed; pedicels slightly thicker thau 

 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 somewbat truncate, tbe 

 two outer considerably sborter 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. Holtze. 



Height l 1 /» — 2 inches. Corolla '/ 4 — V» i ncn long. Fruit as yet 

 unknonn. Koot very short, fasciculate-capillular; but some specimeus 

 placed with this plant show a tender flexuous rhizome elongated to several 

 inches, ininutely ramified, which really seems to belong as a nutritive 

 organ to this species. The aspect of the plant is very much that of 

 Polypornpholyx tenella, particularly on account of the fissurated lower 

 expansion of the corolla and leaves will doubtless yet occasionally 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 Benthara for Sir Joseph Banks's plant, except that the 



lower expansion of the corolla is produced into five almost semi-lanceolar 



divergent lobes ; therefore the Holtzean plant might be distinguished as 



a variety or possibly as a species by the designation quinquedentata . Its 



extreme tenuify 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.
