I think there’s some confusion around J. sandwicensis vs ovalifolia subsp. |

Taxon is fine. J. ovalifolia subsp. flagged |
It's not really a question of whether they are synonyms. They have to be, since they are both based on the same type: https://www.biodiversitylibrary.org/page/28004277#page/519/mode/1up. It is just a matter of which name to use.
GBIF says that J. ovalifolia sandwicensis is the accepted name, but when I try to save the taxon change I get the whale error. I think this may be because the ssp was synonymized with J. sandwicensis at some point, and shows up in the names. If someone else could sort that out it would be much appreciated.
I think there are still some issues when it comes to this and other species in this genus. I wasn't sure which to flag, sorry I am still fairly new to this.
The main issue I see is that it looks like names J. sandwicensis and J. ovalifolia are being used interchangeably for observations in Hawaii. There are many observations ID'ed as either J. sandwicensis or J. ovalifolia but no real distinction is made. I am not sure if there really are both species in Hawaii, or if all of them should be considered J. sandwicensis. This paper established an endemic species J. sandwicensis in Hawaii where it was formerly considered a subspecies: https://link.springer.com/article/10.1007/s10265-009-0258-0 ;

The other issue is the common names are reversed. J. sandwicensis should be given the common name Pa'uohi'iaka, and J. ovalifolia should perhaps be given the common name "Oval-leaf clustervine".
Hi, all- @j92 asked me if I could chime in, so here goes. I can see where the confusion comes from- in the Manual of the Flowering Plants of Hawaii, the native Jacquemontia is listed as J. ovalifolia, which was described as having a subspecies sandwicensis. As Jay mentioned, the Namoff et al. paper (https://link.springer.com/article/10.1007/s10265-009-0258-0 ) established J. sandwicensis as an endemic Hawaiian species, and since then, all checklists for Hawaiian flora have listed J. sandwicensis as the native Jacquemontia in Hawaii, with Jacquemontia ovalifolia (Choisy) Hallier f. subsp. sandwicensis (A. Gray) K. R. Robertson as a synonym. The reference for accepted names used at Bishop Museum is maintained by Warren Wagner at Smithsonian: https://naturalhistory2.si.edu/botany/hawaiianflora/result2.cfm
Clear as mud? :D
TL;DR: the native Hawaiian species of Jacquemontia is J. sandwicensis. Agreed that J. sandwicensis should be given the common name Pa'uohi'iaka, and J. ovalifolia should be given the common name "Oval-leaf clustervine".
They're not based on the same type, J. ovalifolia s.s. is based on a specimen from Africa (though its source was long the subject of confusion): https://www.jstor.org/stable/2395073?seq=1
I agree with @j92 re: common names... the Hawaiian endemic should have the Hawaiian common name.
I've added synonymy from POWO and flagged Jacquemontia sandwicensis as a likely synonym.
