The style is shorter, the stigma much less hollowed out than in M. hypopitys, appearing more like a flat disc. In Sarcodes sanguinea the ovary is smooth, ten-lobed, each lobe extending between two stamens and continued down into a nectar-secreting portion. It is five-celled at the base, becom- ing one-celled above as in Monotropa. The style is erect, bear- ing a five-lobed stigma. In Pterospora the ovary is ten-lobed, depressed. It is five- celled below and one-celled above as in all the preceding. No nectaries are present. The style is short and broad, the stigma peltate-capitate, slightly Fig. 9. Longitudinal section flower Newberrya spicata at base X 25. F = filament, N = nectary, P = petal, S = sepal. In Pleuricospora the ovary is ovoid, not lobed, the epidermal cells bearing distinct pointed papillae. It is four-celled at the base (Fig. 8, 1) and for about one-sixth the length of the ovary, but further up (Fig. 8, 2) the four placentae fail to meet and do not extend far into the interior of the ovary, so that it appears as a one-celled ovary with parietal placentae. There are no nectaries present. The style is short and broad, the stigma depressed capitate. In Schweinitzia the ovary is five-lobed with no downward directed nectaries at the base; it is five-lobed for about half the distance; the placentae do not extend in quite as far as in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - colo
