RlIIZOPHORACEAE. 



Bruguiera Rheedii, No. 212; Rhizophora mucronata, 



No. 213. 



Bruguiera Rheedii, No. 212. 



A medium tree without buttresses. 



Leaves. — Simple, alternate; petiole 1^ to 2 ; blade 



14 to 1\ by 2 to 3| ; elliptical, glabrous, coria- 

 ceous. 



Flowers.— 



Bark. — h inch thick. 



Venation in green leaves very indistinct. 



Vxillary, solitary. Peduncle 



by 



and 



rugged. 



Grey, very rough, 

 Inner bark red brown, streaked 



ridged 



with yellow. Solution cherry; dark green pre- 

 cipitate. 



Wood. — Sap, 1-1, pale yellow; heart brown. 



Rays. — 110; yellow; very slightly sinuous; show 

 up as a beautiful moire silk grain on quarter. 

 Pores. — 7,500-11,500 in more or less porous 

 zones; single; many filled with ruby coloured 

 deposit. Soft tissue. — Absent. General. — A red- 

 brown dense heavy hard wood; straight grained. 



Solution wood: pink; green precipitate. Cuts 



very hard indeed. 71 lb. per cubic foot. 

 Date. — Flowers in Northern Division in July and 

 August. 



Native names.— 



— Bagoia (Buna), Arara (Motu). 

 Remarks. — The wood is used for house posts and 

 has a durability of three years. Bed mangrove. 



Material collected. — Leaves, wood, bark and 

 flowers. 



Locality. — Mangrove swamps throughout the ter- 

 ritory. 



Rhizophora mucronata, No. 213. 



Medium tree with flying buttresses. 



Leaves. — Simple, alternate; petiole, &c., same as 



212, but apiculate more translucent and vena- 

 tion more distinct. 



Flowers. — More or less waxy in texture. 



Bark. — \ inch thick. Same as 212 but inner 



bark red, faintly streaked with yellow. 

 Wood. — Sap ill-defined, yellow, darkening to red 



brown. 



Bays. — 170. Bed brown; not sinuous but often 

 wavy in sweeping large curves; show up well 

 on quarter in wavy bands and streaks. Bores. 

 — 10,000 very evenly scattered; single, mote 

 rarely radially septate (2). Soft tissue. — Ab- 

 sent. General. — A red-brown heavy wood with 

 a pretty figure on the quarter. Solution wood, 

 colourless; a slight discoloured precipitate. Cuts 

 very hard. 62 lb. per cubic foot. 



Locality. — Mangrove swamps throughout the Ter- 

 ritory. 



Date. — Flowers in July in the Northern Division. 



Native names. — Komo (Buna), Totoa (Motu). 



Remarks. — Same use as 212. Unless flowering 

 213 and 212 are hard to distinguish one from 

 the other. The more distinct venation of the 

 leaves and the possession of flying buttresses 

 by 213 makes it really quite distinct when one 

 has learnt to look out for these characters. Both 

 are hard woods with a pretty quarter grain. 



Material collected. — Leaven, flowers, wood, bark.
