Botanical name Dysoxylum rufum
A common name Rusty Mahogany
Seedling
Little Dysoxylum rufum bear little resemblence to slightly larger specimens. The leaves while perhaps slightly hairy are not distincly hairy, they are entire and alternate.
Young plant
Juvenile
I will get some nice photos of juvenile specimens to about 2 metres soon, with furry bits.
Reasonably mature
Sassafras
Now a little older, the alternate leaves have given way to pinnate leaves, in simple terms, a leaf composed of many leaflets. What looks like a row of leaves along a small branchlet is a pinnae, they will eventually fall off in their entirety, not loosing the leaflets seperately.
Dysoxylum rufum are still not particularly hairy or furry at this age.
