OcTOBER, 1923.] THE ORCHID REVIEW. 291 
ORCHID CULTURE IN THE UNITED STATES OF 
AMERICA. 
HE collection of Louis Burk, Esq., in Philadelphia is of more than 
passing interest, as among the five thousand plants here brought 
together from various sources, many have been personally collected by this 
amateur when on his annual trips to Florida. I noted here some remark- 
able pieces of Oncidium Cavendishianum, also some very fine clumps of 
Cyrtopodium punctatum, many of the smaller growing Oncidiums and quite 
a number of Epidendrum species from the same locality. 
As a true lover of plants, Mr. Burk’s enthusiasm is keen, in so much 
that if he robs Florida of some of her wild beauty, he somewhat compen- 
sates the loss by taking out with him each year other Orchids into the 
jungle, where they are established in suitable places. He assured me that 
Phalzenopsis Schilleriana, P. amabilis, P. Esmeralda and P. Rimestadiana 
that were attached to trees a few years ago are now growing vigorously. 
Other Orchids that have been so treated include Vandas and Brazilian 
Oncidiums. 
Mr. Burk is purely an amateur and grows Orchids simply for the 
pleasure it affords him and his friends. His houses are always open to 
visitors, and his kindness is greatly appreciated by the many callers, some 
of whom he hopes will eventuaily become amateurs in this fascinating 
recreation. 
- This collection is quite a varied one, and includes about 2,000 Cattleyas 
and Leliocattleyas, of which 800, or more, are hybrids of well-known 
varieties. The Cattleya house is of the three-quarter span roofed style, 
with a south aspect. The plants are. clean, vigorous, and show great 
Promise for future flowering. The Phalenopses are a splendid lot, and I 
Was indéed fortunate to see the rare P. Harriete in flower, for it had 
recently been described in the Orchid Review. Phalanopses here are not 
§town so warm as in England, consequently they make thicker and shorter 
leaves, but flower freely. Of the 500 plants many were in flower at the 
time of my visit, and I was informed that throughout the whole year 
there are always a few flowering. 
Mr. Burk is fond of Cypripediums and grows about a thousand, 
Principally hybrids of the winter-flowering type. I also noted quite a 
number of Vandas, including specimens of tricolor, suavis and well-grown 
plants of coerulea, but the most envious plants were a dozen nice pieces ot 
x. Sanderiana, which flower well under treatment similar to that given the 
Phalzenopses. 
Mr. H. E. Moase is in charge of this interesting collection. He has 
had a varied experience in the United States, and was formerly in the
