to H.Müller, Befr., p. 355); the anthers are open and the pollen 

 lies loose in them before the corolla has expanded (Fig. 30 D) 

 and before the stigma is quite ripe. Homogamy ensues and 

 lasts for a longer time (according to Lindman and Ekstam "the 

 flower is protogynous-homogamous"). 



The filaments bend inwards and Ihe anthers touch the 

 style (Fig. 31 C). In a smaller form with an ovoid corolla 

 Lindman found the stigma wide spreading. 



Fig. 31. Vaccinium uliginosum L. f. microphyllum Lange. 



A, Open, 5-merous flower from West Greenland (June 29, 1884^ B, Same seen from above. 



C, A 4-merous flower of the same date; there is pollen in the anthers, and-the stigma is 



able to retain the pollen. D, The same seen from above. E, Of same date. F, G, Stamens 



of the same. H, Apex of the style. (E. W., 1885.) 



The stigma is placed just within or at the throat of the corolla, 

 but it scarcely projects beyond it. The anthers stand at a slightly 

 lower level with their appendages spreading straight outwards or 

 directed upwards (in the inverted flower downwards; Fig. 31 C). 

 Consequently the flowers are distinctly adapted for cross-pollina- 

 tion. An insect in search of honey (Fig. 30 L) cannot avoid 

 touching the appendages with its proboscis and thereby shedding 

 the pollen. The following insect-visitors have been observed: 

 Bombus nivalis on the Dovre (Lindman); Bombus consobrinus,
