'''''Ungnadia''''' is a [[genus]] of [[flowering plants]] in the family [[Sapindaceae]], containing one [[species]], '''''Ungnadia speciosa''''', commonly known as the '''Mexican buckeye'''. It is native to northern Mexico, as well as [[Texas]] and southern [[New Mexico]] in the United States.<ref name = GRIN1 /><ref name = GRIN2 /> The name honors Austrian ambassador Baron [[David Ungnad von Sonnegg]], son of Andreas Ungnad von Sonnegg, who brought the [[Aesculus hippocastanum|horse chestnut]] (''Aesculus hippocastanum'') to [[Vienna]] in 1576, introducing the plant into western Europe.<ref name = CRC1 /><ref name = SE1841 /><ref name = Audubon1 /><ref name = SE1839 />{{Failed verification|date=October 2024|reason=Citations do not prove the name actually honours David Ungnad von Sonnegg, son of Andreas Ungnad von Sonnegg|talk=Failed verification of name honouring David Ungnad von Sonnegg}}
It differs from the buckeyes in the related genus ''[[Aesculus]]''  but the seeds and [[nut (fruit)|nuts]] are similar.<ref name=Seeds1 /><ref name=Audubon1 /><ref name = USDA1 /><ref name = USDA2 /> Another similar related genus is the soapberry (genus ''[[Sapindus]]''). ''Ungnadia'' seeds are poisonous despite their sweetness, and sometimes used as marbles.<ref name=Stahl1 /> The foliage is toxic and rarely browsed by livestock, but bees produce honey from the floral nectar.<ref name=Audubon1 />
==Description==
''Ungnadia speciosa'' is a [[deciduous]] [[shrub]] or small [[tree]] (< 25&nbsp;ft) that is often multi-[[Trunk (botany)|trunked]]. The [[leaf|leaves]] ({{convert|5|–|12|in|cm|disp=or}}) are alternate and [[pinnate]]ly compound with 5 to 9 leaflets.  The leaflets are long ({{convert|3|–|5|in|cm|disp=or}}), narrow, and pointed with slight serrations.<ref name = Nokes1 /><ref name=Audubon1 />
