[Taxacom] smallest angiosperm

[Peter Stevens]

I am not sure if this question was asked before, but what is the 
smallest angiosperm?  By smallest, I mean specifically which has the 
fewest mitotic cycles between germination and flower.  I presume 
there are numerous candidates; any little Mimulus/Lepuropetalum-like 
thing that produces a pair of leaves and then a flower.  But is there 
anything that flowers from a cotyledon (I don't count Streptocarpus 
or Monophyllaea)?  I thought also something like Wolfiella might 
count, but I presume there are many "budding" cycles after 
germination and before any one of the little "thalli" flower.
