136 FLOWERS OF THE ROADSIDES AND HEDGES 
menced to produce fruit, the aspect is rather like that of a candelabra, 
and by this time the basal rosette of leaves has usually disappeared. 
The plant is frequently covered with dust, more so than most wayside 
plants. 
It may be distinguished by its small yellow terminal racemes of 
flowers borne on leafless branches. The pods are closely united to the 
stem throughout their length, long, acute above, with sharp style, and 
; borne on short flower-stalks, 
being usually downy. The 
leaves have a_ terminal 
pointed lobe, and lateral ones 
with the points turned back. 
The Hedge Mustard is often 
2 ft. high. It flowers from 
May to July. It is annual, 
and reproduced by seed. 
The flowers are similar 
to those of Alliaria. On each 
side of the 2 shorter stamens 
are honey-glands, and each 
of the 4 honey drops lies 
between the stamens and 
the pistil. The anthers and 
stigma ripen together, and 
the former face the latter. 
The longer anthers are

and project when the flower 
opens and bend inwards; the shorter ones, at first within the flower, 
being ultimately on the same level, but not quite so long as the stigma, 
curve outwards slightly. They all six grow, and the longer ones 
exceed the stigma. Cross-pollination is arranged for, but may not 
occur. In the absence of insects pollen from the four long stamens 
falls on the stigma. The flowers are inconspicuous and visits are in- 
frequent, but honey is sought by /er7s nape, P. rape, which thrust 
the proboscis between the stigma and anthers. Pollen is sought by 
Andrena dorsata. The insects visiting it are Hymenoptera (Apide, 
Andrena dorsata), Lepidoptera, as above. 
Hedge Mustard is dispersed by its own agency. The pods open 
and allow the seeds to fall out around the plant, or disperse them to 
some distance.
