Large-Leafed Tree (Need ID help)

« Back to Name that Plant

Date Photo Taken: October 5, 2010
Location: Decatur, GA
Posted By: Kerimbaev

Notes:

Moderate-sized trees growing along stream bank in the Parkwood Park of Decatur, GA. We thought this might be one of the two mulberry species, just with very large leaves, but weren’t sure. Leaves are as large as 11″ long and 8″ wide, some larger, some smaller, but much larger than your average mulberry leaf. Leaves all ovate and not lobed like mulberries, but serrated like mulberries with a very rough, sandpapery feel. Leaves simple and alternate. The bark had characteristic patches of striated, bulging roughness at regular, wide intervals along the trunk and branches, as seen in the photo. Did not see any flowers or berries.

    Looks like red mulberry, Morus rubra http://campus.murraystate.edu/academic/faculty/howard.whiteman/field/plants/rmulberry.html

    After studying Dirr’s Manual of Woody Landscape Plants 5th edition for a while I believe this is a Bass Wood (Tilia of some sort). The references I have indicate exact id is very difficult and requires being able to spend time with the specimen.
    Will be interested to know for sure.

    Thanks, that’s what I’d decided on. It’s the biggest leafed mulberry i’ve ever seen though — 11 inch leaves not counting the leaf stalk!

    I agree on the basswood. The final check would be to go and knock on the trunk. Many basswoods sound somewhat hollow when you knock. Also, if you break a twig it will not have the milky sap that mulberries do.

    Morus and Tilia can be hard to differentiate.
    There are red mulberries that are absent of lobed leaves…also mulberry leaves have a sandpapery feel and basswood does not.
    Swimdawg is correct, check the sap; mulberry is milky, basswood clear.
    Also, if the tree is immature and/or in shade, the leaves will typically be larger than normal.

    Thanks all of you. The only book I have is Peterson’s guide to eastern trees. The leaves are sandpapery above and below, and the bases of leaves are even and squared off. Book says basswood does not feel sandpapery and leaves have uneven bases. I’m going to try to grab a twig with leaves today and check the sap, try to find evidence of basswood fruits on tree or ground, knock on trunk, see if there are hairs on leaves and twigs, etc. Peterson’s has never failed me in the past although I’ve seen better books with more keys and more detail… Trying to inventory all the trees in Parkwood Park since they are old and huge and we’re trying to clean up the Park of invasives and exotics, but these trees will definitely stay, they are beautiful! The investigation continues….more later!

    Well I can’t reach the leaves anymore — they’re too high up. I was able to reach a large, dying leaf from an off-shoot tree at the base of the big tree, but no sap came out! But the leaf was VERY sandpapery and rough, not like a basswood leaf at all, right? The trunk sounded hollow in some places and some places it didn’t. I didn’t see any evidence of basswood fruits around it. Isn’t it true that male mulberry plants never have fruit? Basically I didn’t learn anything new yesterday, so this tree remains a mystery, but I feel like it’s a mulberry with ginormous leaves. I saw a leaf on it yesterday that was easily over 12 inches long, probably 14 inches no counting the stalk, but I couldn’t reach it. Wouldn’t it be great to have a trained monkey to climb tall trees and bring you things to ID it? :)
