They. ene earthwards, The corolla is 20 mm. in diameter, pale 
blue, with claret-brown patches round the throat, alternating 
with the corolla-lobes. The tube is 8 mm. deep, circular in 
section near the mouth, but pentagonal towards its insertion by 
reason of the way in which the filaments are attached. The 
anthers make a funnel-shaped inverted cone with the stigma 
and shed pollen held in it. They shed their pollen first at the 
downwardly directed yo later from the opposite ends: and it all 
slides down into the funnel. There are five ways to the honey, 
and Anthophora ae te insect which apparently especially 
visits this flower ) ee under the cone as it turns round to 
explore each in turn e pollen is liberated on to fe lower 
surface of its thorax in this act, if the flower be young and the 
stigma immature: when the fawer is older, the now ripe stigmas 
project 4 mm. from the empty cone and are rubbed by the insect’s 
thorax and pollinated if pollen is there. The ways to the teers
