THE ORCHID REVIEW. 215 
I mentioned the frame system of cultivation as a means whereby the 
cooler Orchids may be separated from the warmer during summer, thus 
giving both a better opportunity to have their requirements more strictly 
and better catered for. But where a house exists which is kept solely for 
the benefit of the cool Orchids proper, there is but little doubt that 
it is far and away better than the frame. Such a house must 
now be kept as cool and as moist as possible, giving an abundance 
of air, especially during the night time, and keep it well shaded from the 
hot sun during the day. A few cool growing Lelias do well in this house, 
such as L. harpophylla and monophylla. Many of the Oncidiums also 
enjoy it, such as O. tigrinum, unguiculatum, superbiens, aurosum, concolor, 
cheirophorum (during summer only), Cavendishianum, pretextum, Phalz- 
nopsis (during summer only), ornithorrhynchum, Forbesii, crispum, 
Gardnerianum, Gravesianum, hastatum, dasytyle, curtum, cucullatum, 
incurvum, loxense, macranthum, Marshallianum, zebrinum, varicosum, 
serratum, and spilopterum (Saintlegerianum). Also, as is well known, most 
of the Odontoglossums are best suited in this house. Such genera also as 
Masdevallia, Sophronitis, Pleione, some of the Zygopetalums, including 
Z. Mackayi, Trichosma suavis, Restrepias, Ornithidium Sophronitis, do 
well here. The latter is a pretty little Orchid when flowered well, but to 
do so it requires to be left to grow “ wild” as it were, and ramble over the 
sides of the basket. All the Miltonias also grow well cool during the 
summer, together with Maxillaria grandiflora, M. picta, and M. venusta. 
Many Lycastes also do well here, including L. Skinneri, aromatica, cruenta, 
costata, Deppei, fulvescens and Lawrenceana. Some of the Epidendrums 
do better here, such as E. vitellinum and E. Wallisii, also a few Dendro- 
biums, such as D. speciosum, D. s. Hillii, D. infundibulum, D. Jamesianum, 
D. japonicum, and D. Falconeri, together with many Cypripediums, 
including such well-known species as C. insigne, Boxallii, Spicerianum, 
Charlesworthii, venustum, and villosum, in addition to the great number 
of hybrids resulting from these parents. Then there is Colax jugosus, an 
extremely pretty Orchid when well-grown and flowered; also many 
Cymbidiums, including C. Lowii, eburneum, giganteum, and Mastersii, the 
Auguloas, and Ada aurantiaca. Those plants which require a little more 
heat during the autumn and winter, should be removed to the Intermediate 
house when the cold weather approaches. 
Odontoglossum Schlieperianum, which is of the O. grande section, is just 
now flowering, and will at once commence making growth. It grows fairly 
well cool, but is better in the end for intermediate temperature, especially 
during the cooler half of the year.
