(From excanus, blindness, effect of 'sap.) ■_''■■" 



Flowers monoecious or dicEcious, in terminal or axillary racemes or spiVes. 

 Male flower : Perianth of 3 or 2 very small segments.; No petajs or glands. 

 Stamens 3 or 2, forming almost the whole flower, without any rudimentary 

 ovary ; filaments free or shortly united at the base ; anther-cells distinct, placed 

 back to back, opening longitudinally in 2 valves. ; Feirialp, fl:iwer :, Perianth 

 usually more distinctly 3-lobed or 3-partite than the male. Ovary 3 or 2-ceiled, 

 with 1 ovule in each cell. Styles linear, undivided, freq or shortly united at the 

 base. Capsule dividing into 2-valved cocci. Seeds globular' or ovoid, without 

 any carunculus. Albumen copious ; cotyledons flat, much broader than the 

 radicle. — Trees or shrubs, with a very acrid milky juice. Leaves alternate, entire, 

 or crenulate. Flowers very small, the males clustered 2 or 3 together along .the 

 rhachis of the raceme or spike, or sometiines solitary within each bract. Sitapiens 

 exserted. The females in separate shorter racemes. 



The genus, it taken to include Saphtm, is generally spread over the tropical regions' of both 

 the New and the Old World. Of the three Australian species, one is common on the sea-coasts 

 of tropical Asia, the other two are endemic...
