Typification.

In designating a lectotype for Ipomoea parviflora Sesse & Mocino , we have chosen MA00603909, to which is pasted Sessé and Moçiño’s draft description, in preference to MA603910 or MA603911. This last is Ipomoea costellata . All three specimens are incorrectly labelled in Madrid.

Notes.

Apparently most common in Colombia and Mexico, this species grows at higher altitudes than its close relative Ipomoea indivisa and is rarely found below 1000 m.

A.L. Gentry 22600 (MO) from 26 km E of Olmos in Lambeyeque (Peru) appears to be Ipomoea cholulensis but the material is very poor and further collections are needed to confirm the presence of I. cholulensis in Peru.
