COMMENTS
The leaves of
G. chimborazensis
are lanceolate, and the costa are excurrent, end below or in the apex. There is a variation in the apex and lamina. The apex could be acute to sharply acuminate, which can be found in
one specimen
.The lamina is usually plane, but also can be undulate.
G. macrorrhyncha
is very similar to
G. chimborazensis
in having lanceolate leaves. It differs from
G. chimborazensis
in having a stoutly excurrent costa.
