Discussion
The taxon longipedicellata was originally separated from C. anomala by long pedicels and winter anthesis, and further from C. grandiflora by Macqueen & Hernández (1997: 16) by details of seedlings.
Note that Macqueen and Hernández (1997: 23) attribute to C. grandiflora the types of Inga sericea Martens & Galeotti and I. elegans Martens & Galeottii (Bull. Acad. Roy. Sci. Bruxelles 10: 318, 321. 1843), collected by Galeotti in Oaxaca (nos. 3418, 3235, both BR, not seen by me).
