Taxonomic notes: - Geonoma hugonis is a member of a group of four Central American species, part of the G. cuneata clade, also including G. brenesii, G. monospatha, and G. epetiolata. They all have unbranched or few-branched inflorescences and share the character state of the staminodial tubes being lobed at the apex, but the lobes are not spreading at anthesis and are not acuminate. Geonoma hugonis differs from these species in its internodes covered with reddish or brownish scales.

Taxonomic notes: - Geonoma hugonis is a member of a group of four Central American species, part of the G. cuneata clade, also including G. brenesii, G. monospatha, and G. epetiolata. They all have unbranched or few-branched inflorescences and share the character state of the staminodial tubes being lobed at the apex, but the lobes are not spreading at anthesis and are not acuminate. Geonoma hugonis differs from these species in its internodes covered with reddish or brownish scales. (Henderson, A.J. 2011)/Palmweb. Subspecific variation: - Only one trait (stem branching) varies in this species. There is geographic disjunction but this is likely to be an artifact of insufficient collecting. (Henderson, A.J. 2011)/Palmweb. CultureIt would be best suited for a protected spot in the tropical garden, but may indeed not yet be in cultivation. |
