Phaseolus grayanus Wooton & Standley 1913
Authors/Creators
Description
Phaseolus grayanus Wooton & Standley (1913: 139) [clade A; sect. Pedicellati (Bentham) Freytag].
TYPE: EA Mearns 2124 (HOLOTYPE: US-232982; no isotype indicated in the original publication nor seen during this study).
A widely distributed member of the Pedicellati in the oak-pine forest of the Chihuahuan Desert at 1400–2800 m. Once considered as variety of P.pedicellatus, it deserves the specific rank because of stronger trailing and then climbing stems, slightly coriaceous leaflets with squarish lobes, strong peduncles with 6–14 primary bracts. Phaseolus pyramidalis Freytag and P.teulensis Freytag mentioned in the list of “Vascular Plants of the Americas” (Tropicos 2020) seem to be synonyms of P.grayanus.
