the two ovarian cells, an indefinite number of pendent or campylo- 

 tropous and recurved ovules. The other, Osbornia, has a perianth 

 still more exceptional, since, the corolla being entirely absent, the 

 sepals, eight in number, are imbricate in two series. The cells of

the inferior ovary are also two in number, and often incomplete. 

 In the lower part of their internal angle is seen a placentary mass 

 covered with anatropous ovules. In both genera the leaves are 

 opposite and penninerved. 



III. CHAM^LAUCIUM SEEIES. 



Chamcelaucium ' (fig. 304, 305) has flowers ordinarily hermaphro- 

 dite '^ and pentamerous, with a hollow receptacle, very variable in 

 form, obconical, tubular or urceolate, at the bottom of which is im- 

 bedded the ovary, whilst its upper opening bears a calyx of five 

 small sepals, entire or ciliate, often petaloid. The five petals, longer 

 and inserted in the intervals, are rounded, concave, imbricate in the 

 bud and ordinarily very caducous. The androeeium is formed of 

 two verticils of stamens,^ superposed, five to the sepals and five to 

 the petals and formed each of a short filament, inflexed in the bud
