E. HENDERSONI (Henderson’s). Flower-scape 6 to 8 inches high. 
Leaves oblong, spotted with purplish brown. Flowers slightly fragrant, 
2 inches across, the perianth-segments turned back, pale lilac, the base 
spotted with dark purple; April. Introduced from Oregon. 
Erythroniums succeed best in a mixture of loam and 
peat, or light loam. The most suitable situation for them 
is in the rock-garden or the shrubbery borders. If planted in clumps, 
with the bulb about 3 inches below the surface, they may be left for 
several years, provided they are given an annual top-dressing of fresh 
soil, They are propagated by offsets.

SOME MINOR GENERA 
Natural Order LILIACE 
CaLocuortus (Greek kalos, beautiful, and chortos, grass: grass-like 
leaves). Butterfly Tulips, or Mariposa Lilies. A genus of about thirty- 
two species of bulbous plants (natives of North-Western America), with 
sword-shaped leaves, and showy flowers on scapes. The outer segments 
ot the perianth are sepal-like and much smaller and narrower than the 
inner three, which are bearded on the inner surface and delicately and 
brightly tinted. The principal species are: Calochortus Bentham, rich 
yellow, flowering July and August; C. cwruleus, lilac, with dark blue 
lines and dots, July; C. lilacinus, pale pink, July; C. luteus, yellow, 
fringed with purple hairs, September; C. Nuttallii, pure white, with 
purple spot at base, June; C. pulchellus, bright yellow, July; C. pur- 
pureus, purple without, yellow within, August; C. splendens, purple- 
lilac, August; C. venustus, white, crimson-blotched, with yellow base, 
July. All these are from California, and the colours named have 
reference to the ample inner segments only. They should only be 
grown outside, in sheltered, well-drained, sunny positions, where they 
can be protected from wet from October to March. The most suitable 
soil is a compost of fibrous loam, leaf-mould, and sand in equal pro- 
portions. They are grown in pots by many cultivators, who do not 
care for the trouble entailed in growing them outside. They should be 
potted in autumn and placed in a sunny frame, giving plenty of air in 
dry weather at all temperatures, but keeping the lights closed during 
wet weather, as excessive moisture is the chief cause of failure. Pro- 
pagated by seeds and offsets.
