I have been trying to figure out this plant since last year. I can recognize pea
family flowers more easily, so I just had to figure out the genus and species:
- Leaf blades compound.
- Leave palmately compound or with 3 or fewer leaflets.
- Plants herbaceous or sub-woody.
- Leaves pinnately or palmately compound with 3 or fewer leaflets.
- Leaflets untoothed (entire).
- Leaflets even-pinnate (terminal leaflet modified into a tendril).
(Lathyrus genus)
- Leaves with 2 or more well-developed leaflets.
- Leaves with 2 leaflets.
- Inflorescence with 4-10 flowers. Plants perennial with rhizomes.
- Corollas 14-25 mm long, stems conspicuously winged.
- Stipules 3-10 mm wide and lanceolate to ovate. Corollas 13-20 mm long.
