 sepals whitish, greenish, or dull purplish, early deciduous : stigmato.se style slender-sub- 

 ulate and more or less persistent : akenes either sessile or short-stipitate, moderately or 

 sometimes not at all gibbous.

 walled (except in T. rfjiM/osum) I filaments all capillary and weak: .anthers linear, mucro- 

 nate or apiculate : leaves 2-3- or lowest 4-ternately compound, or last divisions quinate, at 

 least the lower cauline petioled : leaflets (as in all our species) obovate or rounded, or 

 cuneate at base, or subcordate.
