The Korthals collection at L consists of 5 sheets (2 also at B); on one of the smaller fronds the basal pinnae are somewhat reduced and narrowed at their base, but the lowest (of three pairs) on the largest specimen are not, so that there may have been more pairs of pinnae on the latter. Van Alderwerelt's short description of Teysmann's specimen is adequate for identification; the number of pairs of pinnae is not specified.
