    This journal article (you do know that some journals are available online, right?) should be of interest to you http://www.bgbm.org/willdenowia/w-pdf/w34-1Businsk... In it, Pinus orthophylla is described as a new species as discovered (or rediscovered) in 1993. This wan't validly published until 2004, however.

    I specified that it was a "rediscovery", as the trees had been known since 1920, but were misidentified as Pinus morrisonicola Hayata, P. kwangtungensis (P. wangii subsp. kwangtungensis Chen ex Tsiang), or P. fenzeliana Hand.-Mazz.. It wasn't until the present author visited the population that this was described and published as a separate species.

    Anyway, the number of needles per fasicle isn't specifically stated, however, in the diagram of leaves and cones it is shown as having five needles per fasicle. This would make sense, as the species it has been mistaken for either have five, or a variable number (2-5) of needles.

    The citation for the journal in which the article appeared is given as the first line of the Abstract. Willdenowia, by the way, is published by the Botanic Garden and Botanical Museum Berlin-Dahlem http://www.bgbm.org/bgbmpress/willdenowia.htm I understand the preference for using a non-Wikipedia site, but there are legitimate sources of info online. And I expect to see more sources going online, and perhaps some moving to online formats exclusively to offset the costs of publishing and the efficiency with which they can send the information to their readers/subscribers.
