Aim: The present investigation is a survey of ethnopharmacology of medicinal plants and preparations used to manage common ailments within the people of Lekki, Lagos, Nigeria. Method: Respondents from two rural communities (Lekki Oke and Isale Lekki) were used for this study. Results: The survey results returned 43 plants as been commonly used medicinal plants. About 28 (44%) of these had scientific data backing their medicinal usage. Nutraceuticals account for about 37 (58%) of the plants surveyed. About three quarters (74%) of the surveyed plants have multiple uses with verified data corroborating these. The leaves and roots (20%) are the most commonly employed parts of the plant for medicinal treatment, while the stem and whole plant are the least used (2%). Decoction (35%), concoctions (20%) and macerations (17%) are the most common preparation modes of the plant extract...

These pollen zones are equivalent to ten palaeoclimatic zones with alternating dry and wet conditions. The palynomorphs were classified into phytoecological groups and changes in their relative abundances were employed to interpret the palaeoclimatic conditions of their source areas. Contrasting fluctuations in the proportions of the Spore (Pteridophytes) phytoecological group and those of the Poaceae were the main basis for palaeoclimatic inferences. Trends of the occurrence of other phytoecological groups were used to substantiate our palaeoclimatic inferences. In the latest Miocene (5.8–5.5 Ma), climatic conditions were mainly wet until between 5.5 and 5.0 Ma, when extreme dry conditions prevailed. The early Pliocene part (5.0–>3.4 Ma) was generally wet, while the late Plio...

This mangrove underwent many physiognomic changes from the middle to the late Holocene.

There is a wide size range, the equatorial diameter ranging from 20 μ to 75 μ. The shape of the grains, as seen in polar view, is frequently elliptical, but is sometimes rounded-triangular, or circular. The predominant aperture type is a colpus, but five possible trends in aperture development—as well as probable transitional forms—are being postulated, viz. trends towards trichotomocolpate, monoporate, diporate, annulocolpate, and dicolpate grains. The probable derivations of these aperture forms are described and discussed. There is a great variety of exine pattern—punctate, reticulate, negatively reticulate, vermiculate, verrucose, pilate, clavate, spinose, verrucose-reticulate, and clavate-punctate—the most predominant pattern being the reticulate type (terminology according to G. Erdtman).

The identified honey pollen are those of important climatic and environmental indicator species, and clearly reflect the botanical and geographical origins of the honey samples. The implications of this in the study of past environments and archaeology are discussed.
