(Schulz, ' Beitrage,' II, p. 73.)—Schulz says that the flowers of this species usually display well-marked protandry, for the four stigmas only spread out when the anthers have lost all their pollen. Sometimes, however, they begin to do so before the pollen is entirely shed, and automatic self-pollination is then possible. Visitors.—Schulz observed nect-skg. and po-cltg. bees, skg. Lepidoptera, and po-dvg. Diptera. Herm. Miiller noticed 4 bees and 2 Lepidoptera in the Alps (' Alpenblumen,' p. 211). Loew saw Apis, skg., in the Berlin Botanic Garden. 1042. E. Fleischeri Hochst. (= E. denticulatum Ulend.). (Herm. Miiller, ' Fertihsation,' p. 262, 'Alpenblumen,' pp. 209-11.)—The flowers of this species agree in many respects as regard mechanism with those of E. angustifolium, but may be protandrous, homogamous, or protogynous. In all three cases, however, crossing is favoured by the fact that either the diverging stigmatic branches or the stamens serve as the most convenient alighting-place. Automatic self-pollination always takes place should insect-visits fail. Visitors.—Herm. Miiller observed a Syr- phid, 13 bees, 2 fossorial wasps, and 4 Lepi- doptera. Loew noticed a Syrphid (Syrphus balteatus Deg.) and a bee (Halictus minutis- simus K. 5) in
