THE CONSTANCY OF THE BEE. 



87 



Among many other changes which I have noted, where wild 

 flowers were concerned, I may mention Broom to Hyacinth, Hyacinth 

 to Dog's Mercury, Hyacinth to Stitchwort, Stitch wort to Orchis 

 mascula, Linn., Dandelion to Orchis maculafa, Linn., Trifolium 

 repens, Linn., to Tri/olimn jy^'cttense, Linn. (3 changes in 5 visits), 

 Centaurea nigra, Linn., to Scahiosa Succisa, Linn. (2 changes in 7 

 visits), Campanula rotundi/olia, Linn., to Thymus Serpyllum, Fr., 

 and thence to Teucrium Scorodonia, Linn., Anthyllis Vulneraria, 

 Linn., to Lotus corniculatus, Linn., Senecio Jacobcea, Linn., to 

 Carduus arvensis, Hoffm., and from that to Garduus lanceolatus, 

 Willd. 



My most remarkable results were got in gardens, and I will 

 give two cases in detail. The first records the visits of a Hive-bee 

 in the Kibble Palace — 



Cytisus 7'acemosus, Hort., 



Primula obconica, Hance, 



Tremandra ericetata, ... 



Eupatorium (sp. % — pink coloured), 

 „ (sp. ? — white coloured),

 I did not think it necessary to follow this bee any further. It 

 took everything that came in its way, Leguminosae, Primulacese, 

 Compositse — yellow flowers, pink flowers, white flowers, purple 

 flowers — nothing came amiss. The second case is that of a Humble- 

 bee in a garden at Fintry, Stirlingshire, August, 1893. — 



Tropseolum (red flowered),

 I may say that the seed from this bed of Tropseolum was gathered, 

 and a quantity planted behind Kelvingrove Museum. The 

 plants so grown gave a good many pure yellow flowers but hardly 

 a single red one ; and many of them were almost equally blotched 

 red and yellow.
