[NDO-MALAYAN WOODS. 483 



Excoecaria rather numerous and Euphorbia, Sapium and Jatropha very 



few pores. 



(2) Moderately hard woods: Sarcococca, Daphniphyllum, Cycloste- 

 mon, Croton. Of these Daphniphyllum lias numerous and Croton very 

 few pores, while Croton and Cyclostemon show transverse bars. 



(3) Hardwoods: Hemicyclia, Lasiococca and Qelonium. Hemicyclia 

 has conspicuous, Lasiococca and Oelonium faint transverse bars. 



The red-wooded genera are fairly uniform in their structure, so that 

 Phyllanthus, Qlochidion, and Cleistanthus are characterized by pores in 

 short radial strings between regular numerous fine pith-rays. Fluggca 

 has a harder close-grained wood, and Bischofia has rough open-grained 

 wood with rather broad pith-rays. 



In the genera with brown or grayish- or olive-brown wood, Macaranga 

 is verv soft, Mallotus pale-colored and rather soft. Bridelia lias a hard 

 wood of characteristic appearance, and Putranjiva and Baccaurea present 

 transverse bars, the latter wood being lighter and softer. 



The better known genera can be roughly placed in synoptical form as 

 follows : 

 a. White or gray woods. 



b. Soft or very soft: Euphorbia, Jatropha, Givotia. Ostodes, 

 Treicia, Sapium, Excoecaria, Mallotus. 

 bb. Moderately hard: Sarcococca, Daphniphyllum, Cyclostemon, 

 Croton, Baccaurea, Mallotus. 

 bbb. Hard: 11 emicyclia, Lasiococca, Oelonium. 

 aa. Red. 



b. Soft: Macaranga. 

 bb. Moderately hard: Glochidion, Bishchofia, Mischodon, Ghaeto- 



carpus, Aporosa, Macaranga. 

 bbb. Hard: Phyllanthus, Cleistanthus, Fluggea, Antidesma, Mal- 

 lotus. 

 aaa. Brown or grayish-brown. 



b. Soft: Baccaurea, Macaranga, 

 bb. Moderately hard or hard: Mallotus, Bridelia, Putranjiva, Apo- 

 rosa. Daphniphyllum, Cyclostemon. 

 Although no member of the family is of very great importance as a 

 timber tree, it may he worth while to indicate the better known species. 



Aleurites moluccana (L.) Willd. Lumbang (Phil.) ; belgaum; "Indian wal- 

 nut;" "candle-nut." 



Tropical and subtropical regions of the world, the Antilles, Brazil, and 

 widely distributed in cultivation. 



Wood gray and soft. Used for tea-chests.
