Question: Are Cycas and Heuchera both genus of plants ?

Context paragraphs:
Typhonium mirabile: Typhonium mirabile is a species of flowering plant in the Araceae family.  It is found growing in Australia in eucalypts woodlands at the base of "Cycas" plants.  It was first described in 1992 by Alistair Hay, as "Lazarum mirabile" and was the only species in the genus "Lazarum".  In 1997, Hay published a paper transferring it to the genus "Typhonium".

Heuchera: Heuchera is a genus of evergreen, herbaceous perennial plants in the family Saxifragaceae, all native to North America.  Common names include alumroot and coral bells.

Cycas: Cycas is the type genus and the only genus recognised in the family Cycadaceae.  About 113 species are accepted.  "Cycas circinalis", a species endemic to India was the first cycad species to be described and was the type of the generic name, "Cycas".  The best-known "Cycas" species is "Cycas revoluta".  "Cycas" is a very ancient genus of trees.  The group achieved its maximum diversity in the Jurassic and Cretaceous periods, when it was distributed almost worldwide.  At the end of the Cretaceous, when the non-avian dinosaurs became extinct, so did most of the cycas in the Northern Hemisphere.

Micranthes: Micranthes is a genus of flowering plants in the saxifrage family.  It was formerly included within the genus "Saxifraga" until recent DNA evidence showed the members of what is now "Micranthes" are more closely related to "Boykinia" and "Heuchera" than to other members of the genus "Saxifraga".
