Sepal, petal, and staminal nectaries in a hypothetical flower. Sepal nectaries:
at left
= adaxial and abaxial individual glands on a sepal, respectively;
at right
= a whole sepal
modified as nectary. Petal nectaries:
at left
= in the basal part of a petal;
at right
= a whole
petal modified as nectary. Staminal nectaries: at left = a whole stamen modified as nectary;
at
right
= the basal ventral part of the filament nectariferous, two nectaries at the base of the
filament, and an antheral nectariferous appendix, from the base to the top of the stamen, re-
spectively.
Schmid (1988) distinguished the following locations (with a few modify-
cations proposed here) for what he identifies as reproductive nectaries, i.e.,
nectaries located on the flowers, inflorescences, and accessory parts. In each
case, Schmid (1988) proposed several additional appropriate terminologies;
the terms I recommended for their simplicity are highlighted in bold below.
•
Inflorescences (
inflorescence
nectaries)
•
Peduncles or pedicels (
peduncular
or
pedicellar
nectaries)
•
Bracts, bracteoles, or involucra (
bracteal
,
bracteolar
, or
involucral
nec-
taries)
•
Flowers (
floral
nectaries)
•
Ovules in gymnosperms (
ovular
nectaries)
•
Fruits (
post-floral
or
fruit
nectaries)
