Description
A. myryostigma var. strogylogonum is a very beautiful form with a larger flower and rounded, non-angular ribs, unlike typical myriostigmas the 5 fat ribs in adult specimens are always rounded and noticeably curved, making quite a contrast among the other myriostigmas. With age horizontal furrows will mark the sides of the ribs as well the midline line between the edges of two contiguous ribs becomes characteristically ondulated. The stems is also usually darker green, strong, compact and flat. However juvenile specimens up to 3-5 years old have sharp ribs and are virtually indistinguishable from other myriostigmas.
Flowers
The flowers are larger and purely yellow.
