 1 - 3-leaved : leaves nearly as in the preceding, but smaller and usually more hirsute : 

 flowers fewer and smaller : petals obtusely 3-lobed, sometimes flesh-colored. — Bot.

 the densely rough glandular-puberulent calyx : petals somewhat cuneate and with

 small grain-like bulblets. 



6. T. parviflora, Hook. Roughish-hirsute or scabrous-pubescent, a span to a
