Very variable, and composed o f four geographically isolated populations. Each of these has a generally distinctive facies, but variation is sufficient to bring about overlap of all characters, and they are therefore given subspecific rather than specific rank. 1 Lamina cuneate; segments forwardly directed, usually not more than twice as long as wide; petiole usually broad
