Alfaroa Roxburghiana
''Alfaroa'' is a genus of evergreen trees in the Juglandaceae family of the Fagales, growing in montane and submontane tropical rain forests in Central America. The wood is characterized by solid pith, pink heartwood, and vessels with scalariform perforations, as well as simple perforations. Description The (usually pinnately compound) leaves are evergreen and lack stipules. They are alternate, rarely opposite. The plants are monoecious, the male flowers being in lateral panicles (several pairs of catkins on an inflorescence) and the female flowers born terminally either in a single spike or in a hermaphroditic panicle including several paired male catkins. Each flower has a wide bract, two bracteoles, and four sepals. The flowers are sessile. The male flowers have a round or oblong receptacle and six to ten stamens. The pollen grains are approximately 24 micrometers in diameter and are slightly triangular in polar view. The small fruits are nuts, one-chambered at the apex ...

Engelhardia
''Engelhardia'' is a genus of seven species of trees in the family Juglandaceae, native to southeast Asia from northern India east to Taiwan, Indonesia and the Philippines. The genus name is commonly misspelled "''Engelhardtia''", a "correction" made by the original author Carl Ludwig Blume in 1829 and persistent until today, as it was thus entered in the ''Index Kewensis''; the original spelling is ''Engelhardia''. Fossil record ''Engelhardia'' pollen has been found in deposits of Miocene Age in Denmark. †''Engelhardia orsbergensis'' leaf fossils have been uncovered from rhyodacite tuff of Lower Miocene age in Southern Slovakia near the town of Lučenec. †''Engelhardia orsbergensis'' and †''Engelhardia macroptera'' fossils have been uncovered from late Miocene strata in Iceland.
