to H. Mürrer, 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 Liypman and Exsram “the 
flower is protogynous-homogamous”). 
The filaments bend inwards and the anthers touch the 
style (Fig. 31 C). In a smaller form with an ovoid corolla 
Lixpmax found the stigma wide spreading.

Fig. 31. Vaccinium uliginosum L, f. mierophyllum 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. Z, Of same date. F, G, Stamens 
of the same. ZA, 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 ©). 
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 (Lixpmax); Bombus consobrinus,
