  • Description

    Species Description - Notable in the series for few (2-4) pairs of ample, continuously comeous-marginate leaflets, those at tip of each pinna 3-8 cm long, for relatively large capitula, without filaments 6-8 mm diam., and for glabrous stipitate craspedia; in most other respects resembling and seemingly closely related to M. lactiflua.

    Distribution and Ecology - Openings in woodland 450-1350 m, local in s.-e. Oaxaca (mun. Yuautepec and Tehuantepec) and interior w. Chiapas (mun. Tuxtla Gutiérrez), Mexico.

  • Discussion

    The type has obtuse leaflets, but several collections made by T. MacDougall in the municipio of Yuautepec have acuminate ones.
