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".

 "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 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".

Question: Are Cycas and Heuchera both genus of plants ?
Answer: yes
