The petiole
grows from a unique structure beneath the soil known as tuberous rhizome
roots. Tuberous roots are true root tissue that is swollen
possessing tuberous portions that radiate from a central point known as a
crown. The crown serves as the growth point for the
petiole and is effectively the stem. The petiole changes to become
the rachis (RAY-kis) at the point where the leaflets begin to grow
creating a single compound leaf so Marek, you had it

this comes close to the Clivia, except for the strap leaf, which is of
course a giant of a difference. those fat juicy roots are often called
"A bulb" which they are not, and then some sort of chaotic
thing happens and you get strap leaves. Well, as I said it is not an
Aroid but the similarity in root business struck my interest.
