278 BULBS AND TUBEROUS-ROOTED PLANTS, 
TILE ROOT. 
See Geissorhiza, Page 98. 
TRICHONEMA. 
Romuela. 
A genus of pretty little crocus-like bulbous plants, 
natives of the Cape and of the South of Europe. They 
require the same treatment as the Ixia (Page 166). 
The flowers are red, blue, yellow, purple and rose, and 
are produced in spring. ‘These bulbs are not hardy, and 
not of sufficient interest to warrant greenhouse culture. 
This genus is now included in Romuela. 
TRILLIUM. 
American Wood Lily, or Wake Robin. 
But few of our native early flowering plants are 
more showy than the Trillium. It abounds in moist, 
rocky woods, in the Northern and Eastern States, and 
can be successfully grown among shrubbery, if the situa- 
tion is not too dry. The bulbs, or more properly, 
tubers, are small, roundish, and generally deep in the 
ground; they should be transplanted as soon as the tops 
die down, and planted deep. They are perfectly hardy. 
T. grandiflorum.—A magnificent plant; nothing 
can surpass a mass of this when in bloom in its native 
habitat ; color pure white, changing to rose color. 
T. cernuum.—F lowers white, with green and pur- 
ple center, hidden beneath the leaves. Easy of cultiva- 
tion, but not very handsome. 
T. sessile.—A low-growing species, with dark red- 
dish flowers and variegated foliage. 
There are several other species, but 7. grandiflorum 
is the only truly desirable one. 
TRITELEIA. 
A small genus of bulbs, natives of South America 
and California. Their general appearance bears a great 
resemblance to the flowers of Brodiza (Page 45).
