petals with short claw contorted in prfefloration. The androceum is 

 formed of two verticils of five hypogyuous fi-ee stamens. Those super- 

 posed to the sepals have a longer filament furnished outside its base 



with a short glandidar scale. 



The anthers are two-celled, introrse,

dehiscing by two longitudinal clefts, reflexed and definitely extrorse 

 after anthesis. The gynseceum is formed of five alternipetalous car- 

 pels, with fi-ee unilocular ovary containing close to the base an 

 ascendent anatropous ovule with micropyle turned downwards and 

 outwards.^ From the base of the internal 

 angle of each ovary springs a gynobasic 

 style, which unites with the fom- others 

 in an erect tube, only becoming free a little 

 below the apex which is swollen to a 

 stigmatiferous head. The fruit, accompanied 

 by the persistent calyx, is formed of five 

 achenes,- with rugose exterior surface 

 (fig. 53) each containing an ascendent seed 

 whose coats cover a fleshy exalbuminous 

 embryo, with short inferior radicle, hidden by the base of the cotyle- 

 dons (fig. -W). 



The FkvrJcca jDroper only differ, as we have seen, fi'om those of the 

 section Limnanthes by the smaller number of their flower parts. "We 

 cannot on this account alone make of them more than one genus, which,
