Rogers, K. E. 1968. Bull. Torrey Bot. Club. 95 423.
Type Status:
Paratype
Place:
Tonkin,. Province de Thai Nguyen, Vietnam, Asia-Tropical
Collection Date:
Oct 1933
Notes:
Specimen annotated by K.E. Rogers (1968) as "holotype" but protologue designates Balansa 443 as the type collection (holotype: L). This collection is surely a paratype, (mis?) cited in protologue as "1746" but number on label appears to be 4746; locality on label matches locality cited.
"This is neither the holotype nor the paratype of I. tonkinensis."
