Zamia erosa (also, Marunguay) is a species of cycad native to the Caribbean islands of Jamaica, Cuba, and Puerto Rico, described by Orator Fuller Cook and Guy N. Collins in 1903. The species formerly known as Z. amblyphyllidia (described in 1987) was determined in 2010 to be the same species as Z. erosa. It is listed as vulnerable by the IUCN Red List.[1]
Phylogenetical history
[edit]The name Zamia erosa was first applied to a plant found south of Vega Baja, Puerto Rico at the beginning of the 20th century. It was described as having a large fleshy root growing in crevices on forested limestone hills. It had only one or two leaves with broad leaflets with erose-toothed margins.[2] In 1980 a specimen collected in South Central Purto Rico was designated as the lectotype for Z. erosa, and then placed in synonymy under Z. pumila subsp. pumila, a broadly defined species that included all Zamias in the Caribbean and Florida. It has been pointed out that the lectotype was collected 30 kilometres (19 mi) across the Cordillera Central from the site of the original type, that the leaflets on the lectotype were unlike the original description, being narrow, oblong, and with smooth margins at the tips, and that photographs on which the lectotype was based were labelled as Z. media.[3]
Zamia pumila species complex
[edit]Z. erosa is part of the Zamia pumila species complex.[4]
