Identity ofFicus macrocarpa Wt.ex King (=F. amplocarpa nom. nov.) andF. guttata (Wt.) King — A reinvestigation with anatomical evidence

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

The two interesting and endemic but hitherto taxonomically indistinguishable and confused south Indian species ofFicus (F. guttata andF. macrocarpa) were reinvestigated both exomorphologically and anatomically. With the help of data thus obtained their original specific status instead of recently reduced ranks has been restored, better and dependable distinguishing characters have been blocked out and the existing confusions, inaccuracies and inconsistencies in literature have all been rectified. Revised descriptions, illustrations and a workable key are presented. Vegetative anatomy and the descriptions and illustrations of male flowers are given for the first time.F. amplocarpa is proposed as a new name forF. macrocarpa in view of its being a later homonym. It is established that these two taxa belong to sectionNeomorphe King and not toRhizocladus Endl. AnatomicallyF. amplocarpa is considered to be less speciallized thanF. guttata.
