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

 tropous and recurved ovules. The other, Osbornia, bas 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. CHAMiELAUCIITM SEEIES. 



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

 dite 2 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 andrcecium is formed of 

 two verticils of stamens, 3 superposed, five to the sepals and five to 

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

3 They have been described in this genus, 

 as in most of those in this group, as inserted on 



the margin of the disk, in a single series ; but 

 in reality they belong to two verticils, and the 

 oppositipetalous are primarily the more ele- 

 vated. With the stamens alternate an equal 

 number of tongues, often equal to the staminal 

 filaments, and ordinarily, for this reason, de- 

 scribed as staminodes ; they are only perhaps 

 the lobes of the disk.
