linear, with longer claws : filaments longer. — T. lanceolatum, Boykin 

 in herb. Torr. Georgia and Alabama. 



3. T. petiolatum, Pursh. Stem very short, scarcely exserted 

 from the basal sheaths : leaves ovate-elliptic to reniform, 3 to 5 inches 

 long, with petioles as long or longer: sepals erect; petals purple, 

 narrowly oblanceolate, an inch or two long : stamens with short 

 filaments, exceeding the slender stigmas. — Hook. Fl. Bor.-Am. 2. 

 180, t. 192. Idaho, Oregon and Washington Territory. 



-•- -t- Flowers pedicellate : connective not produced. 



++ Pedicel longer than the flower : filament shorter than the anther : leaves 

 sessile or nearly so. 



4. T. erectum, Linn. Leaves very broadly rhombic, 2\ to 6 

 inches wide, shortly acuminate : pedicel usually more or less inclined 

 or declinate: petals ovate to lanceolate, 9 to 18 lines long, brown- 

 purple or often white or greenish or pinkish: stamens equalling or 

 exceeding the stout distinct spreading or recurved stigmas. — Curt. 

 Bot. Mag. t. 470, 1027, 3250; Lodd. Bot. Cab. t. 1838, 1850. T. 

 rhomboideum, Michx., excl. var. grandiflorum. T. foetidum, Salisb. 

 Parad. t. 35. T. pendulum, Willd. Hort. Berol. t. 35 ; Regel, Gar- 

 tenfl. t. 656. T. purpureum, Kinn. From Canada (Nova Scotia to 

 Winnipeg Valley) to N. Carolina, Tennessee and Missouri. It is 

 probably T. obovatum, Pursh, as respects his Canadian plant, and it 

 is apparently also the plant of E. Siberia. The Japanese form is 

 distinguished by a somewhat produced connective and very short 

 stigmas. 



5. T. grandiflorum, Salisb. Leaves less broadly rhombic-ovate, 

 1 \ to 3 or 4 inches wide : pedicel erect or ascending : petals oblanceo- 

 late, often broadly so, H to 2\ inches long, white turning rose-color or 

 marked more or less with green : stamens with slender filaments and 

 anthers, exceeding the very slender erect or suberect and somewhat 

 coherent stigmas. — Parad. t. 1; Lodd. Bot. Cab. t. 1349; Regel, 

 Gartenfl. t. 575. T. rhomboideum, var. grandiflorum, Michx. T. 

 erythrocarpum, Curt. Bot. Mag. t. 855. Vermont to N. Carolina, 

 west to Wisconsin and Kentucky. Sports occur with petiolate leaves 

 or naked stems. 



6. T. ovatum, Pursh. Closely resembling the last ; petals lanceo- 

 late or more narrowly oblanceolate ; stigmas somewhat stouter and 

 more recurved. — T. obovatum, Hook. Fl. Bor.-Am. 2. 180. T. Cali- 

 fornicum, Kellogg, Proc. Calif. Acad. 2. 50, f. 2. From British
