| Summary: | The extrafloral nectaries (30-50) are found on the upper surface of the lamina in Macaranga peltata. Glandular trichomes are restricted to the lower surface while eglandular trichomes are observed on all vegetative and reproductive organs. Nectaries originate from a group of initials and trichomes from a single epidermal cell. Stalkless extrafloral nectaries comprise a 2 to 3 layer secretory zone and 1 to 2 layer sub-secretory zone. The structure of the glandular and eglandular is described. Small black ants are seen visiting the nectary and sucking nectar. The probable functions of nectaries and trichomes are discussed. |
