the pores of the anthers are open and the pollen-tetrads fall 

 out easily (Fig. 36 B). The four petals of the deep-rose-red 

 corolla are quite free, and in the expanded flower they are 

 bent back (Fig. 36 Л). The length of the petals is from 6 to 

 7 mm.; and that of the stamens from 4 to 6 mm. The filaments 

 have fine hairs at their edges; the anthers are covered with 

 small warts (Fig. 36 E,F); they dehisce even in the bud, and 

 before the stigma is ripe, by means of two pores, one at the

In the expanded flower the stamens are erect and stand 

 close to the pistil (Fig. 36 Л ; Fig. 37 J.), which is at first only 

 slightly longer, but gradually increases. The pollen tetrads 

 (Fig. 36 C) are easily shed. 



At the base of the style there is a disk which secretes 

 honey (Fig. 37 B).
