Singapore Botanical Gardens honors visiting world leaders with a registered orchid in their name. This one is for Mike and Karen Pence from their visit in 2018 hen he was Vice President of the USA. (See
this post for more details about the SBG.)
Unfortunately this one wasn't in flower, but at the risk of being accused of only posting orchids named after democrats I thought I would include this anyway. For those wondering, while President Trump did visit Singapore it was only long enough for his (very brief) summit with North Korean Chairman Kim Jong-Un, and he did not visit the gardens so they did not name a plant after him as far as I can tell.
