been given to the timber in question from the resemblance of 

 the fruit {o{ Laurus) to that of the acorn. The species I should 

 designate as 



Laurus (Oreodaphne ?) 7?02f/ei ; glabra hermaphrodita, 

 ramis teretibus Isevibus, foliis coriaceo-ellipticis tripliner- 

 viis brevi-petiolatis basi apiceque acutis, racemis axillari- 

 bus folio brevioribus, pedicellis bracteatis, bracteis folia- 

 Ceis, staminibus 9 biserialibus quorum 3 ext. glandulis 

 geminis munitis, filamentis brevibus, antheris bilocularibiis. 



Our plant is from 3 — 4 feet high, branched, with nearly 

 erect branches, rounded, smooth, clotbetT with dark-brown 

 bark. Leaves alternate, 2 — 2|- inches long, on very short 

 thick petioles, almost sessile above, dark-green, obscurely 

 nerved; below pale, the costae prominent, and branching 

 near the base into 3, the lateral branches running pa- 

 rallel to the margin, and disappearing below the apex. 

 Racemes solitary in the axils of the leaves, and shorter 

 than they. Pedicels bracteated, the bracteas leafy, triple- 

 nerved. Perianth turbinate, six-cleft, jointed on the top of 

 the pedicel. Fertile stamens 9:. of the 6 outer, 3 have 

 large fleshy glands, one on each side. Germen ovate; style 

 shorter than the jjermen. Stiirma acute.
