florescence, and seeds, Ollgomeris and Caylusea. 1 The flower of 

 the former has only the two posterior petals, which may be free or 

 connate. The capsule is 4-lobed at the apex. 

 Five species' 2 are known, natives of the Cape, 

 excepting one from the East. 3 



Caylusea* (fig. 330) has pentamerous flowers 

 with the posterior petals more divided than 

 the anterior. But the receptacle after bearing 

 the perianth rises into a long obconical disk 

 on top and inside of which are inserted the 

 stamens, and the six carpels connate at the 

 base ; these form an ovary open above, wherein 

 the alternicarpellary placentas are so approximated to the lower part 

 as to become almost basilar. Hence the ripe open fruit resembles 

 a six-lobed capsule. Of the two known species 5 one is a native of 

 Abyssinia, the other of Northern Africa, extending also into Arabia 

 and Persia. 



Ochradenus? comprising shrubs and undershrubs from the Medi- 

 terranean, has the flowers of Reseda, but without a corolla : while the 

 pericarp does not open and becomes more or less 7 fleshy at maturity. 

 The four known species 8 have simple linear leaves, often ill developed. 

 Hence their aspect is quite peculiar ; this is the case w T ith Randonia 

 africana, 9 a little branching Algerian shrub, with usually octamerous

 Resedella (Haev.). Three or four superior 

 stamens, of which two alternate with the petals. — 

 2. Holopetalum. About ten stamens of peri- 

 pheral insertion.
