Phaseolus pedicellatus Bentham (1837: 73) View in CoL [clade A; sect. Pedicellati (Benth.) Freytag]. TYPE: WF von Karwinski s.n. (LECTOTYPE: M; ISOLECTOTYPE: US-1326445 ) .

In the original description, George Bentham did not indicate any specimen. There is however a specimen kept in Munich that along the written indications on the sheet has been object of correspondence between Charles Vancouver Piper (at US) and Herman Ross (at M) in November 1924; it can be considered as the nomenclatural type, the specimen at US being a fragment obtained on loan. In spite of lack of data, it might be that the type material (a unicate) was collected in September 1827 near Mexico City during the first trip of Wilhelm Friedrich von Karwinski ( McVaugh 1980). While it is abundant in Sierra Madre Oriental from Pico de Orizaba northwards and the Mexican Trans-Volcanic Belt, it is also known by a couple of collections from Sierra Madre Occidental ( Nabhan 1990; Lépiz-Ildefonso & RamÍrez-Delgadillo 2010). It thrives in pine-oak, oak, mixed (oak, laurel, alder), cedar and fir forest at 1500–2800 m.
