Alien Species in Hawaii

Ardisia elliptica (Myrsinaceae)
shoebutton ardisia


[Ardisia elliptica on Main 8 Haw. Islands]

Status of Ardisia elliptica (Myrsinaceae) on the main Hawaiian Islands as of 08/96

[Map legend]

PRESENT:  at least one knowledgeable person has indicated with confidence that this species is present on this island

MAY BE PRESENT:  at least one knowledgeable person has indicated that this species is not known from this island (and no one has indicated that it is known from this island), but suitable habitat exists on this island, therefore searching for this species on this island may be warranted (ongoing, to monitor whether the species arrives on the island; and/or now, to confirm presence/absence)

ABSENT:  at least one knowledgeable person has indicated that this species is not known from this island, and that this species is not likely to become established on this island due to lack of suitable habitat islandwide

NO INFO:  no one has indicated with confidence any specific presence/absence information for this species on this island

* an asterisk on any island indicates that although the species' presence on that island was reported by a reliable source, we do not cite a specimen-based reference for its presence


This map is based on information collected during a series of meetings of the Alien Plants Working Group of the Hawaii Ecosystems at Risk project, University of Hawaii, Department of Botany, CPSU.  For further details, contact the Hawaii Ecosystems at Risk project.

This map illustrates the estimated distribution of Ardisia elliptica (Myrsinaceae) in the main Hawaiian Islands (U.S.A.).

NOTE: This map is based on the best information available to us as of the publication date. We realize that it may not be complete; we rely on YOU to send us updated information! If you have additional information regarding the distribution of this taxon (including islands on which the species is PRESENT *or* KNOWN TO BE ABSENT), please  obtain a blank all-islands map , indicate the additional info on the map, and send it to: Hawaii Ecosystems at Risk, University of Hawaii, Dept. of Botany/CPSU, 3190 Maile Way, Honolulu, Hawaii 96822 (remember to label the map with the SPECIES you're providing information about, AND your name and contact information). Alternatively, you may fax information to (808) 973­2936, or send e­mail to webmaster@hear.org.

ArcView shapefiles and metadata--including information source and data collection methods--are available from the Hawaii Ecosystems at Risk Project (contact information above). (It is planned that this information will eventually be posted to this site.)

Also, digital photos of this species (or slides, which we can convert and return to you) are solicited for publication on this site.

Again, please remember: this map is a part of a set of WORKING MAPS which will be UPDATED as we receive better information. They are NOT intended to represent "the definitive distribution maps" for any species or island. Rather, we hope that they will stimulate your input based on your own field observations!

NOTE: A goal of this website is to be a reliable source of the most current available information about selected island-by-island distribution of alien species in Hawaii. To maintain reliability of our information, we attempt--whenever possible--to base our information on curated voucher specimens (or sources which cite such specimens). However, in the "real world," the collection and curation of specimens may not occur until after the species is reliably known to be present on an island (sometimes years later). In order to fulfill our goal of timeliness-without sacrificing reliability--we may include data based on information from a source which we believe to be accurate, even if a voucher specimen cannot be cited. In cases where we CANNOT directly or indirectly cite a voucher specimen, the island on the statewide map is marked with an asterisk (*). For further details about the data validation process behind the information presented in this map, refer to the island-by-island mapping section of HEAR's Methods, Standards, and Conventions document.
