structure and nectar chemical composition of some species from Robinson Crusoe Island (Chile).
However, the staminodial nature of the nectary
was put in doubt by Al-Nowaihi & Khalifa (1971) because of the absence of any vascularization.
Ant visitation of extrafloral nectaries in Passiflora: the effects of nectary
attributes and ant behavior on patterns in facultative ant plant mutualisms Oecologia 2001: 409-416.
The interactions conformed to the common behavioral pattern of the larvae everting their tentacular organs and secreting from the dorsal nectary
organs, followed by the ants antennating the larvae and consuming the nectar.
Short-tongued bees bite a hole into the corolla tube close to the nectary
, but, since they also collect pollen, they still have a role in pollination.
Calyx [2 (Obolaria)-] 4-5(-12)-merous; imbricate; usually with a short but well-developed tube; sometimes with basal nectary
gland; lobes rarely reduced or suppressed to appear 2-cleft; rarely winged (Canscora) or inflated and elongated to enclose corolla (Prepusa).
As a first step in determining whether the addition of nectary
plants might increase the abundance and diversity of biocontrol agents of D.
The MhyCRC expression was detected only in flower tissue, confirming its potentially conserved roles in carpel fusion, style/stigma and nectary
development, and in the floral meristem termination as it was shown for A.
Leaves with 2-20 pairs of leaflets; nectary
located on the rachis; flowers asymmetric.
The size and color of the flowers and the presence of a massive nectary
disk suggests insect, likely bee or wasp, pollination.
morphology in South West Asia Fritillaria (Liliaceae).
Occasionally, however, long-tongued bees and ants have been observed visiting them, possibly attracted to a nectary
found near the ovary of the chasmogamous flower.
