Callitropsls araucarioides was met \\\t\\ in a single liniitotl locality, M'lu^ro 

 it was flrfst noticed by my companion, the late Paul Denys Monfagno. It 

 was growing freely on the serpentine rocks by the side oE the I{. du Caronage, 

 bordering on the Plaino des Lacs, at an altitude of about 800 £t. It 

 apparently belongs to the serpentine scrub formation, in the same way 

 as does Dan\fj(Uum araucarioideSy to wliitdi it hears some resemblance. 



LiBOCEDRUS AUSTROCALEDONICA Brongn. t Gris, Nekando ; in coniferous 

 forest above 3500 ft, ; serpentine. 1072, 2020- This is the oidy species of 

 Libocedrns recorded for New Caledonia, and has only been collected so far 

 from the Nekando-Mont Humboldt massif, where it grows in mixed coni- 

 ferous forest at altitudes above 3500 ft., though never in luxuriance. It 

 IS a small symmetrical tree, never growing to more than 20 ft- in lieiolit, 

 and of a spare habit. The male cones are now described for the first 

 time :
