May, 1923.| THE ORCHID REVIEW. 14t 
favourites of mine, and one of the best was Marshallianum, which I bought 
newly imported some years ago. This is an exquisite Orchid, and with 
tigrinum, Forbesi and varicosum, well worth growing. These plants were 
all successful with me, one particular plant that did well being Oncidium 
flexuosum majus, a better form than the type. 
The Coelogynes including Massangeana, barbata and speciosa, were ait 
happy in my greenhouse, and I often remarked that it would have been 
impossible to have killed the first-named plant, so vigorous was it. In spite 
of its colour it is an interesting plant. Ccelogyne cristata was only a partiab 
success, no doubt due to my interference. Most of the Dendrobiums died 
out from want of heat and moisture during the growing season, but a few 
did fairly well, including Wardianum, nobile, and the hybrid Rolfee. D. 
thyrsiflorum did well for atime. The nobile plants, however, in spite of 
making good growths, failed to bloom, probably from lack of sunshine, and 
failure in ripening their bulbs. One experienced considerable difficulty in 
giving the different Orchids grown together 1 in one house the correct treat- 
ment at all seasons. 
Regarding other plants in the collection I might mention Ada aurantiaca, 
a vigorous grower, Cochlioda Neetzliana, which grew strongly but. refused 
to bloom, Miltonia candida flavescens, another strong grower, but flowering 
never. Then there was the dainty Sophronitis grandiflora, which looked 
better in bloom when my few plants were colonised, and the superb Stan- 
hopea tigrina, which bloomed once with me, but failed to make good ina 
cool intermediate temperature. There were others, but I need not catalogue 
them, 
HyYBRIDISATION.—I started making some crosses in 1918-19 with Cym- 
bidiums, Cypripediums and Odontiodas, and in 1920 made a few sowings 
after giving away some of my seed pods. One plant of Cymbidium insigne, 
which was never too robust, never recovered properly after it had ripened 
its fruit. I have not yet heard of any successful results from the seed given 
away, but not long after Mr. Mundy, the Orchid foreman, removed the 
second portion of my plants to the Royal Botanic Gardens in November, 
1920, he discovered some Cypripedium seedlings on a pot in which Cyp. 
Thalia was growing. These seedlings turned out to be Baron Schroder X 
villosum aureum, and when I saw them this month they had been potted in 
2in. pots and were looking healthy and vigorous. They were certainly a 
Jong time in germinating, and probably other seedlings may have been lost 
in the removal. I am told that Cypripedium Baron Schréder is a shy 
flowering plant. The one in the Gardens has that reputation, and my plant 
was not too keen on flowering. I fully intend taking up this interesting 
branch of Orchidology once I make another start, when probably I shall 
have better facilities for seed raising.
