Chamaesyce skottsbergii var. vaccinioides is endemic to the Hawaiian Islands. It has been recorded from the islands of Molokai, Maui, and Kahoolawe. On Maui, it is only known from a single specimen collected in 1920 on the south slope of Haleakala (East Maui). There are only two Kahoolawe specimens. One was collected in 1913 on the east coast. The second specimen was collected on the south coast in 1980, when a single plant was found. On Molokai, the taxon is still locally abundant, although the numbers most likely have dropped significantly as a result of large brushfires burning through much of the taxon's range in recent years. Prior to the fires it was thought that the number of mature plants might be be in the range of 3,000-5,000 (Lau 2000). Historic reasons for the decline of this taxon on Molokai include the conversion of much of West Molokai to agricultural land in the early 1900's, and cattle grazing, which continues today. Other contempory threat factors are deer, feral pigs and goats, and the spread of alien plant species.
Questionable number of populations with individuals numbering anywhere from 1000 to 5000. Found on Moloka`i only (USFWS 2001).
