Maybe a linden tree? Linden are the European name while Basswood is the North American name. There are about 30 varieties in Tilia
"Tilia is a
genus of about 30 species of trees or bushes, native throughout most of the
temperate Northern Hemisphere. The tree is known as
linden for the European species, and
basswood for North American species.
[1][2] In Britain and Ireland they are commonly called
lime trees, although they are not related to the tree that produces the citrus fruit
lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the
Cronquist classification system, this genus was placed in the family
Tiliaceae, but genetic research summarised by the
Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the
Malvaceae.
Tilia species are mostly large,
deciduous trees, reaching typically 20 to 40 m (65 to 130 ft) tall, with oblique-cordate leaves 6 to 20 cm (2+1⁄4 to 7+3⁄4 in) across. As with elms, the exact number of species is uncertain, as many of the species can
hybridise readily, both in the wild and in cultivation. They are
hermaphroditic, having
perfect flowers with both male and female parts, pollinated by insects."

"Heat Output
Linden Trees do not burn very hot or provide long-lasting coals once the fire dies down. But, the wood does light with great ease when dried right and burns very fast. So if your purpose is for warmth or cooking, choose another kind of wood.
It has fewer than 14 BTUs (British Thermal Units), which makes it a poor-quality wood for fires in general. However, it depends on the purpose of your fire and what time of year it is."
You can burn it if there’s nothing else available, but it doesn’t produce very much heat at all and it burns quite fast. It’ll work in a pinch but if there are other woods around, it’s advisable to use those instead.
