Flower devel­op­ment in Balsaminaceae

Balsaminaceae con­sist of two gen­era, the mono­spe­cific Hydrocera and its species-rich sis­ter Impatiens; how­ever, mor­pho­lo­gical sup­port for the cur­rent molecu­lar phylo­geny of Balsaminaceae is low. Janssens et al. invest­ig­ate the floral devel­op­ment of H. tri­flora and I. omei­ana, two early-diverged lin­eages in the fam­ily, and find that in Hydrocera the peri­anth devel­ops into a less-zygomorphic peri­anth com­pared to its sis­ter genus. The devel­op­ment of the androe­cial cap and the gyn­oecium fol­lows sev­eral dis­tinct onto­gen­etic sequences within the family.
