SUMMARY

This paper deals with anatomical descriptions of some types of nectaries in 27 species of honey plants of Piracicaba, S. P.

The material studied was divides in two groups: a) Extra-floral nectaries; b) Floral nectaries.

Euphorbia pulcherrima, Willd; showed to belonging to the first group: its nectaries tissue consist of an epidermal layer of cell without stomata and with true gland, with subepidermal cells diferentiated by the thickness of the wall.

Among the plants with floral nectaries, the following types has been listed, according the location of the nectary in the flower: 1 - with true glands: a) in sepals, Hibiscus rosa sinensis, L.; Dombeya Wallichii, Bth. e Hk; b) in the stamens tube, Antigonum leptopus, Hook e Arn.; 2 - on the receptacle with nectariferous tissue in the epidermal cell with: a) thickness wall with stomata, Prunus persical, L.; b) thin wall without stomata, Crotalaria paulinia, Shranck; Caesal-pinia sepiaria, Roxb; Aberia caffra; 3 - with a disc located in the receptacle with: epidermal: a) with stomata, Coffea arábica, L. var. semper florens; Citrus aurantifolia, Swing; Cinchona sp.; Pryrostegia ignea, Presl.; b) without stomata and with thin wall, Leojurus sibiricus, L.; Bactocydia unguis, Mart., Ipomoea purpurea, L.; Greviüea Thelemanniana, Hueg.; Dolichos lablab, L.; Vernonia polyanthes, Less., Montanoa bipinatifida, C. Koch., Eruca sativa, L. Brassica Juncea, Co; Eucalyptus tereticomis, Smith.; Eucalyptus rostrata, Schleche; Salvia splendens, Selow.; 4 - in the basal tissues of the ovary, Budleia brasiliensis, Jacq F.; Petrea subserrata, Cham.; 5 - in the base of stamens, Per sea americana, Mill.

On the anatomical point of view, most of the types of nectary studied has external nectariferous tissues, located on the epidermal cells with thin periclinal wall and without stomata. The sub-epidermal layer were rich in sugar.

Short correlation was found between the structure of the nectary and the amount of nectar secretion. So, in the nectary with true glands, in those with thin wall and without stomata on epidermal cells and in those with stomata, the secretion was higher than in the other types listed.
