Type Information

Ab Indis dicitur Mala erikaliga ... H(eyne) in Osyre Indiae Orientalis
Distribution Of Types
Orissa (India, Indian Subcontinent, Asia-Tropical)
Type Remarks
collection: B. Heyne sub Convolvulo


Heyne made the collection in Orissa and coined the manuscript name Convolvulus orixensis (as seen from his hand-written annotation on a syntype specimen); Roth misread Heyne's epithet as osyrensis and published the same. The publishing authors Romer and Schultes ascribed the name and the description together to: Roth ... MSS. Therefore, Roth is the author of the species name (see the ICN Art. 46 Ex. 22)
