Lets's talk about plants, shall we?

Hello, and I have a ? about 2 plants:
1. What is the origin of the Mallorn?
2. What is the name and origin of the white, leafless tress atop of Cerin Amroth?

No need to answer # 1 I found it out by reading Unfinished Tales. the malinore came from Eressea to Numenor then to Lindon (not planted there) but given to Galadriel. I still wonder about #2.
