Jan, in earlier ruminations, did you not suggest that the in a possible
_Pinguicula_ raceme as in 4., the bracts may be enlarged and indistinguishable
from "leaves"? Does this mean _Pinguicula_ germinates, produces a stem
with short internodes (and leaves at the nodes), but at some point this stem
transforms into a raceme? The raceme bears bracts indistinguishable from
"cauline leaves", so the initiation of a flowering stalk is never apparent?
How is this supported as opposed to _Pinguicula_ producing solitary terminal
flowers from the axils of cauline leaves? (I would guess it is supported by
a need to correlate with other Lentibulariaceae inflorescence types, but if
Lentibulariaceae displays racemes, cymes, and panicles, is a solitary terminal
flower too far-fetched?).
