    Why did you put the family name, Sapindaceae, as a key word above the Acer grandidentatum picture?

    Thanks, I needed this. We have a sugar maple in our front yard. I have been tempted to tap it. The Mathias report is most appreciated. I was concerned that tapping could cause irreversible damage to the tree. I now wonder how one prevents the infestation of insects to the puncture site. There is probably a preferred method. Also, should one ‘dress’ the wound site after puncture? These questions are yet to be addressed. I appreciate the link, thanks, again.

    Bob,

    Recent molecular analysis of plants such as Acer (maple), Aesculus (horsechestnut) and Koelreuteria (golden rain tree) confirms what most 19th Century botanists saw clearly: that there is little real evidence supporting the separation of these genera into separate families.

    What are the respective publication dates of Aceraceae, Hippocastanaceae and Sapindaceae?
    I’m rather surprised – given that most 19th century botanists were from the temperate northern hemisphere where Acer is by far the most familiar genus in the group – that the families were merged under the name Sapindaceae, rather than under the name Aceraceae, as I’d have thought that Aceraceae would have been named earlier due to the familiarity of the type genus

    Sapindaceae and Aceraceae were both described in 1789 by Antoine-Laurent de Jussieu. Hippocastanaceae was separated later, by DC. in 1824.

    What is interesting is that both Aceraceae and Sapindaceae were published by Jussieu in Genera Plantarum on August 4, 1789, so I’m not sure why Sapindaceae has priority. Perhaps the date that the descriptions were written? I don’t have access to the book to try and find an answer.

    Thanks; if they are the same date, it should be following the usage adopted by the first botanist to combine the two families into one. Presumably it was someone who was more familiar with Sapindaceae than Acer (odd as that possibility may seem to our temperate point of view!).
