134 MISSOURI BOTANICAL GARDEN BULLETIN 
Syringa.—Varieties of syringa are among the best of the 
lilac-colored flowers. Any florist’s catalogue will give a num- 
ber of varieties from which to choose. 
Vitex Agnus-castus—The popular name for this shrub is 
the chaste-tree. It is a graceful plant 5 to 6 feet high, bear- 
ing in late summer dense spikes of lilac-colored flowers. 
Reference to its use in connection with Kerria japonica fl. pl. 
has already been made. 
Caryopteris Mastacanthus or Blue Spiraca.—This is not a 
very hardy plant but is well worth trying. It requires a 
well-drained and loamy soil, a sunny location, and a little 
rotection in the winter. The lavender-blue flowers are 
orne in great profusion in the summer and continue bloom- 
ing until frost. It grows from 2 to 3 feet high. 
Buddleia Lindleyana.—The Chinese Buddleia or summer 
lilac is a beautiful free-flowering shrub, but requires a light 
porous soil and a sunny exposure for its best development. 
The violet-purple flowers bloom in midsummer and are pro- 
duced in dense, arching racemes from 4 to 8 inches long. 
This is a splendid plant, growing from 5 to 8 feet high and 
holding the foliage until after frost. 
(To be concluded.) 
THE DOVE ORCHID 
The dove orchid (Peristeria elata), an account of which 
was given in the December, 1914, Butuerin, will again be 
in bloom the early part of November. Visitors to the Garden 
should not fail to ask where this plant is, since it is, as may 
be seen from the accompanying plate, one of the most curious 
and interesting orchids grown in the Garden collection. 
CHRYSANTHEMUM SHOW 
The annual display of chrysanthemums will be held in 
the new floral display house, beginning the last Sunday in 
October and continuing throughout the month of November. 
Both because of the number and variety of plants and the ex- 
pei Sega fine house in which they are to be shown, the 
exhibit will surpass any previous display of this kind ever 
held at the Garden. The show will be open every week day 
from 8:00 o’clock until sunset and beginning with Sunday, 
October 31 until December, every Sunday from 2:00 p. m. 
until sunset. From December until Easter the Garden will 
be closed on Sunday, but throughout the winter a continuous 
display of blooming flowers will be maintained in the new
