    I wonder if anyone can offer any information about or sources relevant to the following oak species:
    Quercus seibertii
    Quercus davidsoniae
    Quercus oocarpa
    Quercus panamandinaea
    Quercus corrugata
    Quercus copeyensis (AKA bumelioides)
    Quercus seemannii
    Quercus gulielmi-treleasei
    Quercus baruensis

    These species are listed & described in Flora of Panama & occupy a niche environment near the Costa Rican border above 1200m.
    I'm especially interested to know if any of these have been re-named, re-categorized, or are no longer considered extant species.
    I am aware that Maarten Kappelle has written about some of these species, but have been unable thus far to access any of the articles written by him online.

    Hi Michael,
    I appreciate you taking the time to check these out, as I consider you the nomenclature guru here at the UBC forum. I don't know anything about its reliability, but I found the following site that does list most (all?) of them as valid names, although I did read in "Tropical Plants Of Costa Rica" (Zuchowski, 2005) that at least one, Q. copeyensis, has had a name change:

    Go by the dates of the notations. Apparently that last one was collected and identified as the Q. insignis in 1935, then subsequently determined to be Q. siebertii, only to be returned to Q. insignis in 1994. It may reflect a naming sequence the entire species Q. insignis has gone through, or it could show that there has been some differences of opinion about the placement of that particular specimen.

    FWIW note also that specimen at last link above is designated as an isotype of Q. siebertii.

    Thanks, Ron
    It does look like the current designation (by some, at least) is Q. insignis.
    http://mobot.mobot.org/cgi-bin/search_vast?ssdp=01001087

    It also appears from Seibert & Woodson's writings (Flora Of Panama I) after that plant collecting expedition that he identified it as such, but with some reservations:
    "QUERCUS INSIGNIS Mart. & Gal. Chiriqui: valley of the upper
    Rio Chiriqui Viejo, vicinity of Monte Lirio (Seibert 225).
    According to Trelease's recent monograph of the American
    Oaks, this species has previously been known only from southern
    Mexico. Our specimens, taken from trees not infrequent
    in the valley of the upper Chiriqui Viejo, certainly accord well
    with the Mexican representation although the margin of the
    leaves is apparently quite entire in most cases, and the acorns
    average somewhat smaller, but not consistently so."
