54 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Occurs sporadically and occasionally throughout the range 
of the species. 
In addition to the white variety, various intermediate 
shades of color occur. Т. obovatum Pursh probably repre- 
sents one of these, or it may belong with Т. grandiflorum. It 
appears probable that these are original variations, and not 
the result of crosses between the extremes, though the pure 
white form probably appears directly as a mutation. Speci- 
mens from Oswego, Ithaca, and Utica, N. Y., Mt. Carmel, 
Ш., southern Pennsylvania, Cincinnati, O., and Hennepin Co., 
Minn., show various intermediate shades, and some from Port 
Huron, Mich. and other localities are pale purple.

Willdenow's figure differs from that in the ‘Botanical 
Magazine’ in having the leaves acuminate instead of obtuse. 
The flowers are also probably smaller. 
Rare. Near Annapolis, Nova Seotia, Macoun (Cat. Can- 
adian Pl. 1: 48. 1888.). Macoun also mentions a rare form 
with green petals from Peterboro Co., Ontario.

This plant may be distinguished from T. erectum by its 
‘Jong, slender filaments, smaller stigmas and peduncle, which 
is deflexed beneath the leaves before anthesis." The flowers 
are larger and are said by Small often to have a rose-like 
fragranee, the sepals to be more or less involute above the 
middle, and the petals ovate or orbicular-ovate, 4-6 ст. in 
length. Judging from specimens, the plant is also usually 
larger than T. erectum, from which it was probably derived. 
Moist woods in high mountains, North Carolina, Tennessee, 
Georgia, and in Connecticut.
