identification for new Jacquemontia found in Taiwan
Recently an unidentified species of Jacquemontia was located in Taiwan by Dr Yang Sheng Zehn, who asked my help to identify it. We co-authored the account of Convolvulaceae in the Flora of Taiwan, edit. 2, and we have never seen this species before. I believe this is an adventive, newly discovered and documented from Taiwan and seek your help to identify it. Some photos of the living plants in habitat are below; the high-resolution image files are attached to this blog post. The locality data for the population are as follows:
nomenclature for Ipomoea flammea & Convolvulus igneus
I am concerned about the correct epithet for the Brazilian plant we are looking into, so did some checking for the protologues for 2 names above. I was able to track down the original publication for Ipomoea flammea Nees [in Flora 4: 301. 1821] and that name was published on 21 May 1821. Then in a subsequent article [Flora 4: 329] dated 7 June 1821, Nees equated "36. Convolvulus igneus Schr. ist Ipomoea stammea m." [this has to be a typo for 'flammea'].
Operculina ? flammea

A friend of Maria Teresa recently found in the field a species that none of us could identify, but George and Dan suggest it might be this little known species they came across when preparing the Flora Neotropica account.

[Operculina flammea (Nees) Meisner in Martius, Fl. Bras. 7: 212. 1869.
