Of late years these Trilliums have been becoming more 
and more cultivated on rockeries in our English gardens. 
The finest species is 7. grandiflorum of Salisbury, of which 
there is a good figure at Tab. 855 of the Borantcar 
Macazinz, under the name of J. erythrocarpum. The 
present species is one of the dwarfest of the genus, and is 
distinguished by its distinctly-petioled leaves and white 
petals without purple stripes. It inhabits woods in the 
North-western States from Ohio westward to Wisconsin. 
Our drawing was made from the plants that flowered in the 
herbaceous department at Kew this present summer. 
Desor. Rootstock an oblique oblong tuber, with numerous 
wiry radical fibres. Peduncle without any leaves below the

with red-brown, with a membranous sheath at the base. 
Leaves always three in a whorl, oblong or ovate-oblong,
