Crested and monstrose forms

Description and meaning of the name

Cristata describes crested growth, in which the growth zone elongates to produce a fan-shaped stem. Monstrosa covers irregular disturbances of stem structure. These features appear with various species and cultivars in the gallery. A record should state the species or line and specific growth type. Irregular growth forms do not all belong to the same cultivar. [Szychowski b.d.a] [Anonim b.d.e] [11-WWW] [11-WWW]
