Fumeria bulbosa has long nectary on one side & abortive one on other just like in Antirrhinum, as in former case an insect to get into nectary, would almost necessarily push back the hood from its mouth thus leaving exposed & upright the stamen & ; the hood cannot be pushed back from other side with mere abortive nectary which doubtless has no honey.

How are nectaries in double columbines &c &c

There are some fringes on hood i.e two united petals / which fringe must aid insect in pulling back hood, like the wing-petals
