Tn i - i c shrubs, very rarely herbaceous plants. Leaves without stipuli . 

 alternate, ample or pinnate, covered with pellucid resinous •!..;-. ri.,w,r- axi] 

 terminal ', regular or irregular. Calyx 

 in 4 or 5 ah iaiona. Petals either ae many 

 as the divisioua uf the calyx, distin 

 c omb ined into a monopetalous corolla, or 

 occasionally wanting ; eestivation for the 

 most part twisted, verj rarely somewhat 

 valvular. Stamens equal in number to 

 the petals, or twice or thrice as many, or 



even fewer in consequei of abortion, 



li\ pogj nou8,verv ranK juTi^viious, placed 

 on the outside of a disk or cup surround- 

 ing the ovary, and either free or combined 

 with the base of the corolla, or in part 

 abortive, < (varj - saile or Btalked, its 

 lobes equal to the number of petals 

 fewer : ovules twin and collateral, or one 

 above the other, rarelj I. seldom more ; 

 style single, occasionally divided towards 

 the base into as many parts as then 



- of the ovary ; stigma simple or 

 dilated ; ovules usually 2, sometimes I, 

 partly ascending, partly suspended. Fruit 

 n ral capsuli -. either coher- 

 ing firmly or more or leas distim 

 twin or -Miliary, with a testaceous integu- 

 ment; embryo with a superior radicle, 

 which is either Btraight or oblique, and 

 cotyledons of variable form; albumen pre- 

 sent or absent 



There are two principal divisions in this 

 Order ; the one Rotes proper, which 

 have seeds containing albumen, and a 

 fruit, the aarcocarp of which is said not to 

 separate from the endocarp ; the other 

 Diosmese, whose seeds have no albumen, 

 and whose aarcocarp and endocarp divide 

 into distinct bodies when 1 1 1 . - fruit i> ripe.
