Andromonoecism occurs on Dovre. In a dense in- 

 florescence the lowermost flowers were purely c?, while the 

 uppermost ones were more or less distinctly ^. cJ > ? (see 

 Fig. К and J). In S the petals were 9^/3 mm and in ? 8 mm 

 in length. In ^ the pistil is smaller, the ovules are smaller 

 and compressed, but appear otherwise to be fairly normal, 

 only the stigmas are undeveloped (Fig. k^, k^, ä;^, compared 

 with i'^, i^, 1^).

According to LiNDMAN dimorphous 5, protogynous- 

 homogamous. He has described more closely the variations 

 which occur in the structure of the flowers: (a) some flowers 

 are larger than the others, but are more inconspicuous and 

 have shorter stamens, the petals do not reach to the throat 

 of the calyx; they are dull dark-red (Fig. 39, A, A^^ a^). The 

 flowers are protogynous, and the styles twisted; (b) others 

 are smaller, have protruding petals and longer stamens 

 (see Fig. D, C); he regards them as approaching to c^. The 

 calyx is thinner and lighter coloured. The anthers stand at 

 a higher level than the stigmas. 



^ The cliaracters on which the genus Wahlbergella is founded are 

 very insignificant, and the genus ought not to be retained; also 

 the characters are not correct; as for instance the record in Hart- 

 mann's Flora that the claws of the petals of Wahlbergella are 

 wingless, but those af Melandrium are winged, or that the seeds 

 have a membranous edging; for M. triflorum, which evidently 

 stands very near to the two Wahlbergella's, has wingless seeds 

 (see Fig. 41, Я).
