Orpo LXXXIII. SANTALACEZE. 
This Natural Order is represented in tropical Polynesia by Santalum and Exocarpus, the latter genus 
including Æ. Gaudichaudii, Alph. de Cand. (E. cupressiformis, Hook. et Arn., non R. Br. ?), from the 
Sandwich Islands, and Æ. phyllanthoides, Endl., from Norfolk Island. There are no specimens or drawing 
of Forster's Xylophylla longifolia (E. longifolius, Endl.) at the British Museum, and no locality is given in 
Forster’s Prodromus for this plant; the uncertainty lingering about his species I have it, therefore, not 
iu my power to clear up. Can it be a species of Pseudopanax from New Zealand ?
