. Notes on the life history of British flowering plants. Botany; Plant ecology. 336 BRITISH FLOWERING PLANTS Tbucrium Protandrous bee flowers. The upper lip is apparently absent, as in Ajuga. We have four species. T. Scordium and T. Botrys have axillary flowers. In the other two they are in terminal one-sided spikes; T. Scorodonia has pale yellow, T. Chamoedrys red flowers. When the flower opens the anthers stand out at the orifice; afterwards they bend up, and their place is taken by the stigma. T. Scorodonia (Wood Sage).—The corolla-tube is 9-10 mm. long, sometimes nearly half filled with nectar. When the lower flowers of a raceme have reached the second (female) condition (Fig. 220), the upper ones are still male (Fig. 219), so that a bee first visits female flowers, and then dusts itself with pollen, which it probably carries to an- other plant. The plant is pubes- cent. T. Chamsedrys.—According to H. Miiller the pistil is only as long as the shorter stamens, while according to Schulz it exceeds the longer ones. The leaves are pubescent; the stem hairy. It is not a British plant, but found, rarely, as a garden escape on old walls. Lycopus In this genus the stamens are reduced to two. The complete flowers are protandrous ; there are also smaller ones which are female. The corolla - tube is only 3-4 mm. long, and the nectar is therefore accessible even to insects with a very short proboscis. It is represented in our flora by L. europseus, a. Vig. 219. Fig. 220.
