ciali imbricatis. Petala 5 calyce parum longiora, æstivatione 
eonvoluta. Stamina 10, filamentis basi in annulum confluenti- 
bus alternatim brevioribus; antheris parvis bilocularibus. Dis- 
cus —? Ovarium ovatum 5-loculare, loculis 1-ovulatis, ovulis 
anatropis ex apice anguli interni suspensis. Styli 5 fere a basi 
distincti subulati. Fructus —— 
Frutex Austro-Caledonicus glaberrimus, siccitate nigrescens, facies 
Irionanthis. Folia alterna in petiolum attenuata oblonga basi

apices ramulorum 3 v. 4 approximati, vix ultra sesquipollicares 
simplices v. subdivisi ; bracteæ lineares subulatæ pedicellis vix 
+ lin. longis dimidio breviores ; flores inaperti eos Ardisiarum
