286 The Romance of Wild Flowers 
anthers all turn down to get in the way of the bees. 
Afterwards, the lower stamens part sufficiently to 
allow the stigma to pass between them and come in 
the way of visitors. Should there be a scarcity of 
such visits, then the pollen, of course, remains on the 
anthers, and in all probability some of it will get 
upon the stigmas from the shorter stamens. 
The Ground Pine (A. chamcpitys) is a plant of 
local occurrence in the chalk districts. It has solitary 
yellow flowers, the lower lip spotted with red, and 
the leaves are split up into three slender lobes, which 
have suggested the plant’s name from their resem- 
blance to pine leaves. This great departure from the 
shape of the leaf in the other species is remarkable, 
but may be explained by an observation of Sir John 
Lubbock’s: he found it growing in the Riviera among 
Cypress Spurge (Huphorbia cyparissias), a plant 
with leaves similar to the leaf-segments of Ground 
Pine, and with yellow flowers. Cypress Spurge, like all 
its family, is rich in a poisonous milky juice, and if it 
should prove that Ground Pine commonly grows in 
such company it is easy to understand its departure 
from the characters of its nearest relations: as in 
the case of the Dead Nettle, the resemblance to a 
poisonous plant would have a distinct protective 
value.
