? Perianthium ut in mare ? Squamulce plurae ovatae, per cliscum floris 

 spars*. Pistilla numerosa, villosa. Pericardium corticatum, e peri- 

 anthia tubo efformatum intus pilosum, stigmatibus proniinulis cerona- 

 tum, in quatuor partes patentes dehiscens. Caryopses plures, subulatae, 

 pilosae. Arbores {Chilenses et Nova Z elan dice) glaberrimce, semper- 

 virentes (odore Lauri sassafras valde redolenles), 5 — 20 orgyales et 

 ultra. Folia opposita ovalia, peiiolafa, serrafa. Flores axillares, ra~ 

 cemosi vel subcymosi.

 racemis multifloris incano-villosis. 



New Zealand (Northern Island). A tree thirty feet high, on the margins of 

 the streams falling into the Keri-Keri river. — 1826, A. Cunningham. 



Of this very remarkable plant the tree bearing the female fructifi- 

 cation has not been discovered in its native country. I have, never- 

 theless, not' only placed it in Mr. Brown's family Atherospermea , to 

 which it most assuredly belongs, as indicated by its opposite serrated 

 leaves and by the structure and mode of dehiscence of its anthers, 

 which, however, accord with those of the Laurinaz, but I have re- 

 ferred it to Pavonia of Ruiz and Pavon, of which it appears a second 

 species, although it is dioecious, and the female flower and fruit re- 

 main yet to be examined.
