Arctic Plants: Morphology and Synonymy

butions to the knowledge of the flowering and fecundation of Scandinavian 

 mountain plants. This author observed on Dovre mountain two types of flowers 

 of this species, the one being larger but less conspicuous and with the stamens 

 shorter; the other with the petals more developed and with longer stamens. 

 _ Lychnis apetala L. has a very long (about 40 cm.), persisting primary root 

 which remains very slender, however; similar very long lateral roots proceed 

 from near the crown of the primary one. While in small specimens the crown 

 of the root bears a more or less compact rosette of leaves, such leafy rosettes are 

 in larger specimens borne on a distinct complex of subterranean stem-bases at 

 a distance from the crown, thus representing a pseudo-rhizome; in large specimens 

 the diameter of the rosette measured about 12 cm. 



L.affinis J. Vahl shows the same structure of the vegetative organs as the 

 preceding but the plant is smaller. A very tall species is L. Taylorae Robinson, 

 measuring in height about 28 cm. but of the same habit as the species described 

 above; it was collected along Mackenzie bay by Rev. Isaac 0. Stringer (1893).
