STERN BERGIA—STRUMARIA—TIGRIDIA, 275 
pensate for the greenhouse treatment they require. All 
require a very strong, rich soil, and the Coburgias do 
well in the open border, but flower better if grown in 
pots, as in the border they are more disposed to make 
offsets than flowers. If grown in pots, which is the best 
way of treating them, they should be plunged in the 
open borde1 until the leaves are fully grown, when they 
may be brought into the greenhouse to develop their 
flowers. 
S. coccineum.—Scarlet. Native of Peruvian Andes. 
S. incarnatum (Coburgia).—A very large bulb, and 
requires planting from five to six inches deep. Flowers 
cup-shaped, of a bright crimson color, with green spots 
on each petal. Keep perfectly dry during winter. 
S. i. fulvum.—A more delicate variety, with light 
orange flowers. It succeeds best in the open border, 
and the bulbs are stored like the Gladiolus during win- 
ter (Page 115).

STRUMARIA. 
A small genus of Cape bulbs allied to Nerine (Page 
21), and requiring to be grown in the same manner. The 
flowers are red, white or pink. They are of dwarf habit, 
and thrive with ordinary greenhouse treatment. 
TIGRIDIA. 
Tiger Flower or Tiger Iris. 
These singular Mexican bulbs have no equal for gar- 
den display, when we consider their ease of culture, the 
length of time they are in flower, their magnificent col- 
ors and singular forms. Their remarkable flowers are 
of but short duration, never lasting more than a day, 
but are produced i such successive abundance as to 
compensate for this defect; one plant will continue
