278 BULBS AND TUBEROUS-BOOTED PLAXTS. 



TILE ROOT. 

 See G-eissorhiza, Page 98. 



TRICHOXEMA. 



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. 



TEILLIUM. 



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 Xorthern 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. — Mowers 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 T. 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 Brodiaea (Page 45).
