| The nectary is supplied by a single vascular bundle comprising xylem and phloem. |
| At the anthesis, a nectary is present at the base of the ovary and trichomes can be observed on the ovary epidermis. |
| Many possess, at the base of the ovary, a disc-like nectary from which nectar is secreted via modified stomata. |
| As is now regarded as typical of bat-pollinated flowers, the corolla is sturdy and the nectary disk is large. |
| 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. |
| Its nectary tube is five inches in length, and as slender as a knitting-needle. |
