I may add, as an instance of this, and of a striking case of correlation, that I have recently observed in some garden pelargoniums, that the central flower of the truss often loses the patches of darker colour in the two upper petals; and that when this occurs, the adherent nectary
is quite aborted; when the colour is absent from only one of the two upper petals, the nectary
is only much shortened.
The monophyly of Eurybiini is supported by the presence of tentacle nectary
organs (TNO) on the larva, dorsal confinement of the intersegmental membrane between the eighth and the ninth segments of the pupa, presence of bristle-like scales on the medial surface of the palpi, metallic bluish-green compound eyes, and further 3 characters from the male genitalia (Harvey 1987; Hall 2003).
3c, d and 4d-f), sometimes slightly lobed and interpreted as a nectary
ring that measures between 1.
azora in Riodinini is reinforced by the position of spiracles, presence of echinoid setae, and absence of tentacle nectary
organs, which are all typical features of this tribe (Harvey, 1987; Kaminski, 2008).
The plants produce small flowers that have a small nectary
in the center which secretes nectar that attracts a variety of insects that are potential pollinators (Stevens and Hawksworth, 1970; Hawksworth and Wiens, 1996).
regarding its fundamental origin as a possible nectary
or aerophore" (Mickel and Beitel, 1988; Mickel and Smith, 2004; Lehnert, 2006).
is of the cuniculus type and produces an insufficient amount of nectar for quantification of total sugar content.
He expected that the production will increase in 2010 due to the heavy rainfalls and the wide availability of nectary
and wild plants.
0,7 mm wide, flattened, not thickened towards the apex, yellowish; anthers linear, subdorsifixed, slightly sagittate, with a thick green connective and dark brown to blackish thecae, pollen yellow; ovary conical, the lower 1/3 (= nectary
tissue) sunk into the receptacle, yellowish, nectary
tissue orange, the superior part 7 mm long; ovules white, the flat chalazal appendage about half as long as the ovule proper; style ca.
lt;p>In England, in Tudor times, they called the plant 'larkspur', for they saw that the nectary
(found in the foot of the nectar sepal) represented a lark's claw.
A young nectary
has a plug in an orifice, and as the nectary
matures, the plug is expelled and an additional new orifice, with a plug, is added.
The compounds could simply be leaking out of the plant into the nectary
