dens, a few years ago, as Vittadinia triloba, and which Dr. Sender, mis- 

 taking it for the genuine Australian plant of that name, has described 

 as Erigeron trilobwn, is manifestly De CandoUe's Erigeron mucrona- 

 tum, of Mexico and Venezuela. 



V. CUNEATA, DC. {Euryhiopsis gracilis, Hook. f. and probably V. 

 dentata, DC.) is not well named. The perennial root, undivided leaves, 

 and less rough pubescence distinguish it from the preceding species. 



V. SCABRA, DC. (Eifi-gbiopsis scabrida, Hook. f. E. Hookeri, Son- 

 der). Miiller's plant, or at least the var. angustifolia, accords pretty 

 well with the character of De CandoUe's V. scabra. It appears to be 

 distinguishable , by the less copious and shorter pappus, and by the less 

 attenuated achenia, which are evidently margined by ribs considerably 

 stronger than the facial nerves. 



§ 2. EURYBIOPSIS. — Achenia minus elongata, marginato-biner- 

 via, faciebus baud striatis. Pappus uni-pluriserialis. Cajt. sect, pras- 

 cedentis. 



V. HiSPiDULA (F. Miill. ined.) : undique scabro-hispida sen hispi- 

 dula ; caule erecto e radice annua stricto oligocephalo ; foliis caulinis 

 linearibus sessilibus imisve spathulatis paucidentatis ; ligulis e pappo 

 leviter exsertis ; acheniis appresse-hirtellis obovatis apice breviter acuta- 

 tis faciebus enerviis pappo fere uniseriali brevioribus. — Eastern and 

 Tropical Australia. 



V. MACRORHiZA (Eurgbiopsis macrorhiza, DC.) if rightly identified 

 with Dr. Miiller's specimens from " Providence Hill," considerably re- 

 sembles dwarf and narrow-leaved forms of V. scabra, but the faces of 

 the achenia are nerveless, as in V. kispidida. The' pappus is more 

 copious than in the latter, and about the length of the (immature) linear 

 achenia. 



V. HUMiLis (sp. nov.) : suffruticosa, e basi crassa multicaulis ; cauli- 

 bus foliosissimis ; foliis anguste spathulatis integerrimis undique hispidis 

 sen hirtellis aveniis, costa subtus incrassata ; pedunculis brevibus soli- 

 tariis vel subumbellatis ; ligulis uniseriatis flores disci (6 - 12) vix super- 

 antibus stylis duplo longioribus ; acheniis lineari-oblongis marginato- 

 binervatis hirtellis estriatis pappo subtriseriali ina'quali dimidio brevi- 

 oribus. — Variat foliis hirsutioribus vel subglabratis, nunc fere linearibus 

 basi longe attenuatis. — Sandwich Islands, on the mountains of Hawaii 

 and Maui. — This species manifestly connects the original Tetramolo- 

 pium with Eurybiopsis. A depressed and glabrate variety, from the 

 district of Waimea, Hawaii, makes the nearest approach to the Tetra-
