24 MISSOURI BOTANICAL GARDEN BULLETIN 
Insects upon imported orchid plants, according to our ob- 
servations covering a number of years, are extremely rare. In 
fact, during the last fourteen years, only two shipments were 
infected with borers. These are commonly referred to as the 
orchid fly and the dendrobium beetle, and their eradication, 
according to our experiments, was a simple matter. In the 
early stage the presence of the larvae is indicated by an ab- 
normal swelling of the young growth from strap-shaped to 
pear-shaped. (See Missouri Botanical Garden BULLETIN, 
Vol. 4, page 88.) Orchids are generally imported to a perma- 
nent destination, unlike roses, carnations, etc., which are an- 
nually vegetated to be shipped to all parts of the country, and 
it is therefore policy for the florist to keep his plants under 
strict observation for depredating insects. 
Unless the government order is rescinded the florist will 
have to turn from the showy epiphytic types to the terres- 
trial or semi-terrestrial lady’s slippers. Raising even this 
variety from seed would not be profitable. The present stock 
of orchids in this country may be rapidly increased, however, 
by the annual division of the vegetative growths which read- 
ily adapt themselves to this medium of propagation. In the 
western states it is essential to divide the parent plants 
periodically to increase flower production. 
NEW HYBRID LADY’S SLIPPER 
A new hybrid lady’s slipper raised in the Garden orchid 
houses during the last five years has just produced its first 
flower. This is the first slipper orchid raised at the Garden 
to reach the flowering stage and will bear the name of ‘‘D. S. 
Brown”’ in honor of the man who brought the Garden orchid 
collection up to the present standard. The parents of the 
hybrid were Paphiopedilum barbatum Crossti, a native of the 
Malay region, and the hybrid P. Harrisianum superbum. 
Both were dark-flowering types, but the color of the offspring 
is greenish yellow with a prominent white dorsal sepal, the 
upper portion being flushed with bright purple. The mar- 
gins twist back with age, resembling P. villosum, the parent 
of P. Harrisianum. The general shape of the flower suggests 
P. Harrisianum, with the exception of the broad dorsal por- 
tion with its prominent venation, this being plainly indica- 
tive of P. barbatum.
