Stems are 2 angled, margins have low to deep crenations, at times undulating or frilled (slightly to deeply scalloped), bristles are absent. Basal stems are indeterminate (seasonal growth is various lengths), unreported x unreported. Main stems are determinate (seasonal growth is about the same length), 15cm x 4.5cm.

Taxonomic treatment and description were derived from:

The referenced publications below
- published material was examined and consolidated
  - to determine minimum and maximum size ranges
  - to determine color variations and shapes
In rare cases
- if minimum and maximum values were unreported, authors examined their own materials
- if clearly observed colors were unreported, authors expanded the botanical descriptions
