COMMENTS

The remarkable character of Groutiella tumidula is the lingulate leaf with acute apex and percurrent costa. G. tumidula is similar to G. apiculata and G. obtusa in having lingulate and rounded-obtuse leaves. The differences between G. tumidula and G. apiculata are discussed in comments of G. apiculata . G. obtusa differs from it in having rugose leaves.
