In Dumfriesshire, 7 hover-flies and several Dolichopodids were recorded (Scott-Elliot, 'Flora of Dumfriesshire,' p. 84). 1244. G. Mollugo L. (Herm. Muller, ' Fertflisation,' pp. 300-1, ' Weit.

Ed. i, II, p. 344.)—The small white flowers of this species are arranged in conspicuous inflorescences. Hermann MUUer describes them as protandrous. Like all our native Rubiaceae, they secrete nectar on a disk above the ovary, and surrounding the base of the style. The quantity is very small, and forms only a thin Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Knuth, Paul, 1854-1899; Knuth, Paul, 1854-1899; Mu?ller, Hermann, 1829-1883; Ainsworth Davis, J.
