• Discussion

  This species agrees in most respects with G. glaberrima R. E. Fr. (known from Ecuador), which, however, even in early stages of development has quite glabrous branchlets and leaves. Tn G. longcdccurrcws the network of veins is very elevated and conspicuous, especially on the under side. It differs from G. glaherrima also in its broader, ovate-lanceolate leaves.
