nectariferous การใช้

• Each consists of a nectariferous pad with filamentous rays arising from its edge.
• These carry pollen loads comparable to those of nectariferous birds, making them effective pollinators.
• The highly fragrant, nectariferous flowers vary from white ( rarely ) through pinkish and purplish and occur in umbellate cymes.
• The genus is characterized by the lack of a nectariferous disk and is associated with the multiple-bang flowering syndrome.
• Visits to " Banksia " inflorescences by western honeybees and nectariferous birds are often observed and are obviously important to pollination.
• The smooth nectariferous disc are traits found only in the new world " Hymenaea " section " Hymenaea ".
• Pollinators have not been recorded for the species, but extensive data from other " Banksia " species suggests that insects, birds and nectariferous mammals would all play a role.
• In his " Anatome plantarum " is a longitudinal section of a flower of " Nigella " ( his Melanthi, literally honey-flower ) with details of the nectariferous organs.
• In this regard they are similar to the Proteaceae, with which they share, for example, a nectariferous hypogynous disc, although they differ in the number of floral parts and the radial pentameric symmetry is completely original.
• Also important are visits by nectariferous mammals, although such visits are rarely observed because these mammals are usually possums and yellow-footed antechinus, " Antechinus flavipes " ), and rodents ( such as the pale field rat, " Rattus tunneyi " ).
• The staminate ( male ) flowers are without either corolla; they consist simply of stamens, varying in number from two to 10, accompanied by a nectariferous gland and inserted on the base of a scale which is itself borne on the rachis of a drooping raceme called a catkin, or ament.
• The very similar " E . howellii " is more restricted in its range and can be distinguished by its lacking of nectariferous appendages on the bases of the inner petals . " E . hendersonii ", which has a distribution that ends just at the northern boundary of the cream fawn lily, is fairly similar, but is easily distinguished by its purple flowers . " E . oregonum ", which is wide ranging and fairly abundant in southwest Oregon can be distinguished by its deeply divided three-lobed stigma ( whereas " E . citrinum " is narrowly divided ).
