 L. alternate, elliptic or elliptic-lanceolate, blade 3-S, pet. J-^ in. long. Fl. minute, 

 bisexual, in axillary panicles 2—1 in. long, peduncles and pedicels slender. Perianth

Oedbb XCVIII. EUPHORBIACE^;. Gen. PL iii. 239. 



Herbs, shrubs or trees, milky sap in some genera. L. alternate (exceptions : 

 Jluius, Mischodnn, 7V< n-ia, Cirlml ixctis, species of Mal/otu* and E.ixacaria , 

 undivided (exceptions: Bischqfia, Dalechampia), usually stipulate. Fl. 

 mostly small, nearly always unisexual. Perianth usually simple and calycine, 

 petals present in several genera, connective often thick and large. Ovary 

 superior, as a rule of 8 carpels, more or less united, styles as many as cells or 

 carpels, free or united, ovules 1—2 in each cell, pendulous from the inner angle. 

 In manj r genera the micropyle is covered by an excrescence of the placenta 

 (caruncle). Fruit either a capsule of 2-valved l-'2-seeded cocci, usually 

 separating from a persistent axis, or a drupe. Embryo straight, radicle 

 generally superior, cotyledons in nest cases broad, flat in a fleshy oily albu- 

 men, in a few genera cotyledons fleshy without or with scanty albumen. 



Baillon and others separate Buxus and Sarcococca (raphe dorsal, micropyle towards 

 the axis) from Euphorbiacece. In Engler u. Prantl iii. 5. 130, they and a few other 

 genera form a separate order : Buxacece. All genera here described belong to the 

 Division of Platylobece, the genera with narrow cotj ledons I Stenolobeat) are limited to 



Australia and South America. 



In species of Oroton, Ilymenocardia, Macaranga, Mallolim, Coccoccras, and Homonoia 

 the underside ol I, is densely clothed with minute orbicular often shining scales, 

 consisting of radially arranged cells or rows of cells. In these cases as well as in 

 BZceagnuit, I/, ,ilirru and ot her 1 1 s. the close covering of these minute scales doubt less 



affects the t ranspiral ion of the leaves as well as the interchange of air. Their action 

 probably is analogous to thai of a dens.' felt of stellate or other hairs. No sharp limit 

 exists bet ween i lii-se sea les and t he tlat stellate hairs which clothe the underside of I. in 

 some of the genera mentioned ami in ot her genera of this Order.

 ing several fl. without perianth, viz., one central l + fl. (a pedicellate pistil) and 

 several $ h\, each a single pedicellate stamen.

II. Flowers not united in heads, each fl. with a perianth, 2 ovules in each cell, as 

 a rule collateral, iu a few cases superposed, one pendulous from the apex the other from
