Description

310d. Mimosa polycarpa Kunth var. subandina Barneby, var. nov., a var. polycarpa et var. spegazzinii vix nisi calyce asymmetrice paleaceo, contra bracteam suffrulcrantem in lobulos setoso-decompositos 1-3 producto diversa, ulterius dispersione subandina extratropica divergens. —Argentina. Salta: depto. Campo Santo, Güemes, 3.IV.1945 (fl, fr), C. A. O’Donnell 2696. —Holotypus, NY; isotypus, not seen but cited by Burkart, 1948 sub M. polycarpa, LIL.

M. polycarpa sensu Burkart, 1948:147-149, t.17 (right), sens. restr.; non Kunth.

Lfts of larger lvs 22-jug. upward, glabrous on upper face; calyx as described in diagnosis and in key to varieties.

On brushy hillsides and river banks, and weedy along highways, ascending to 600(-?) m, locally plentiful in subandean valleys of n.-w. Argentina, from Jujuy to Tucumán, and adj. Tarija, Bolivia; reported by Burkart (1948 sub M. polycarpa) from Sta. Cruz, Bolivia, this record to be confirmed. — Fl. XI-V(-?). Map 46.

Several leaves of Venturi 8062 (UC) consist of two pairs of pinnae, such as were mentioned for M. stenoptera by Burkart (1948: 153, footnote 2). This abnormality is so rare that I have not thought it worthwhile to provide a lead in the foregoing keys.
