| The three-lobed labellum is attached to the column by a column foot, where the nectary is located. |
|
| Ipomoea alba with longer flower tubes correspondingly had the highest mean total nectar volume per flower and nectary volume. |
|
| Finally, nectar collects in the saccate nectary spur formed by the fusion of the margins of the labellum and the base of the column-foot. |
|
| Many possess, at the base of the ovary, a disc-like nectary from which nectar is secreted via modified stomata. |
|
| The nectary is supplied by a single vascular bundle comprising xylem and phloem. |
|
| Saccate nectary at base of floral tube formed by partial fusion of labellum and column. |
|
| At the anthesis, a nectary is present at the base of the ovary and trichomes can be observed on the ovary epidermis. |
|
| As is now regarded as typical of bat-pollinated flowers, the corolla is sturdy and the nectary disk is large. |
|
| A large vascular bundle comprising xylem and phloem elements supplies the nectary. |
|
| The family is characterized by various kinds of sclereids, hypophyllous glands and specific nectary bracts. |
|
| Major morphological differences in the family are found in the type of inflorescences, and the shape and position of the nectary bracts. |
|
| When the nectary is on the inside of the calyx, it probably ensures that the corolla is fused at most only basally. |
|
| The bee enters the tunnel to get at the nectary, and as the bee backs out some of the stigmatic fluid may be rubbed on its back. |
|
| At the base of each petal is usually one nectary gland that is naked or may be covered by a scale. |
|
| The nectary is of the cuniculus type and produces an insufficient amount of nectar for quantification of total sugar content. |
|
| One group includes the families Rutaceae, Meliaceae, and Simaroubaceae, which share a nectary disk between the anthers and carpels and similar secondary compounds. |
|
| These have a nearly continuous spiral of bracts, sepals, and petals, then numerous stamens, a nectary disc, and separate carpels with expanded stigmas. |
|
| The hairs guide the pollinating insect to the base of the petal, where there is a purplish nectary covered by a flap of tissue. |
|
| The depression is formed by the midvein on one side of the nectary and a secondary vein on the opposite side. |
|
| Nectar secreted in alternistaminal troughs on staminal tube or staminal feet or from disclike nectary around base of ovary, more rarely from sides of ovary or absent. |
