are wind-pollinated. But they may be insect-polli- 

 nated, by flies. A little honey is secreted. The 

 male flowers are rose-colour, the females purple. 

 The stamens protrude from the perianth. The pistil 

 is short, with six to nine spreading, black, and shining 

 stigmas. There are some plants which have com- 

 plete flowers, in which the anthers ripen in advance 

 of the stigmas. The flowers are borne on short 

 shoots, arising laterally from the main axis. 



The drupe is edible, and dispersed by birds. The 

 drupe contains many small one-seeded stones. 



The name Empetrum means growing in stony 

 places (Greek en, petron). 



The Crowberry goes by the following names : 

 Crake-berries, Craw-berry, Crawcrooks, Croupans, 

 Crow-berry, Crow-peas, Goose-berries, Heath, Black- 

 berried Heath, Wire Ling, Monox Heather, Moonog, 

 Crow Pea. 



Empetrum nigrum. — The heath-like habit of the 

 Cvowherry is admirably shown in Fig. 34. The stamens 

 are seen to project a long way from the flower.
