134 WILD FLOWER FAMILIES 
To find the pure white blossoms of the Par- 
tridge Vine or Twin-berry you must seek the 
shade of the pine woods early in June, where the 
brown carpet of fallen needles is variegated with 
4 the dark green, oval 
leaves of this plant. 
The flowers are always 
borne in pairs, each 
terminating a short 
branch. Later they 
give place to the curious 
| double fruits which, 
when red and _ ripe, 
give the plant its com- 
mon name. The flow- 
ers are tubular, with 
four flaring petal lobes. 
On the front of these, 
as well as inside the 
tube, are numerous fine 
white hairs, making a 
thicket that effectually 
prevents any wandering 
ant from crawling 
down the tube and stealing the nectar, which 
is thus reserved for the bees that bring about 
cross-pollination. This is insured by the fact 
that in some flowers the stigma projects in the 
mouth of the corolla and the stamens are low, 
while in others this condition is reversed,
