Accession Data:
- Accession # 198500199
- Source: Unknown
- Provenance:
- March 2017 - This accession is undocumented, its long-standing presence (pre-1985) in the living collection and the presence of (3) greenhouse herbarium specimens dating to May, 1968 are likely one and the same. The herbarium also contains one specimen collected in June 1967 as Aristolochia ringens, but subsequently determined as Aristolochia hians. The possibility exists that the original 1967 specimen was also brought into the greenhouse collection at that time, but has retained the Aristolochia ringens ID.
