Floral Formula
Floral symmetry, sepals, petals, stamens, carpels, fruit type
- means:
radial floral symmetry
X means:
bilateral symmetry
$ means:
asymmetric floral symmetry
dashes before and after # of sepals (ie. -5-)
tepals
Line above # of carpels
inferior ovary
Line below # of carpels
superior ovary
dashed lines
feature is typical, but varies between taxons
solid lines
feature is characteristic
”+” means:
differentiated parts
ie. 5 stamen alternating with 5 smaller stamen = 5+5
circled numbers mean:
fused
- if dashed lines: typically fused
circled numbers with connections to other parts
adnate fusion
ie. stamen fused to petals
“K’ means:
Calyx (sepals)
“C” means:
Corolla (petals)
