 mucronate : peduncles numerous, 4-12-flowered : sepals very long, lan- 

 ceolate-acuminate, 2 // -3 // long, strongly hairy, often exceeding the

Var. prairea Mackenzie & Bush, n. var. Leaflets 6 /x or less long : 

 flower-spikes hardly paniculate : flowers 3 /x long, on pedicels \" long. 

 The common form on dry banks throughout. Possibly a distinct species.
