leaves, waved, entire, acute, or Somewhat acuminate at the 
extremity, with three principal nerves and several lesser 
proceeding from these larger ones. From the centre of 
these leaves arises a curved flower-stalk, an inch to an inch 
and a half high, solitary, and producing a single flower, 
which is slightly drooping. Calyx of three lanceolate 
leaves, about half as long as the corolla, entire, green, often 
slightly margined with red. Petals three, spreading, oval, 
acute, waved, pure white, nerved, each having a large 
purple spot near the base. Stamens six, three opposite, 
and attached to the base of the petals, and three alter- 
nate with them. Filament dilated upwards, where, on the 
posterior side, are two linear, longitudinally-opening cells, 
abounding in white pollen. Pistil: Germen oblongo-oval, 
obsoletely three-angled, crowned with three sessile, recurv- 
ed, white stigmas, which are minutely glandular above. 
All the species of the Genus T'ritxium are well deserving 
of cultivation in every collection of hardy plants: this is 
eminently the case with the present individual, which is 
rendered the more conspicuous, from its otherwise pure 
white petals being marked with a bright purple stain. It 
is probably not unfrequent in the more northern of the 
United States of North America, and in Canada. Our 
plants were sent to the Glasgow Botanic Garden by Mr. 
Crrcuorn from Canada, and they flowered in the month of 
April, having been slightly sheltered during winter.
