CULTIVATION OF ORCHIDS.

but in more shade, otherwise give them much the same kind of treatment. The following 

 beautiful species deserve a place in every Orchid collection : Bollea ccelestis, 

 B. Schroderiana, B. Patini, Pescatorea Klabochorum, P. Sanderianum, P. Lehmanni, P. Dayana, 

 P. cerina, Batemannia Burti, B. Wallisi, B. Colleyi, B. grandiflora, Huntleya Meleagris, 

 H. Candida, Warscewiczella Lindeni, W. Wendlandi, W. discolor, and W. cochlearis. All 

 should be grown in well-drained pots or pans, using a compost of three parts Sphagnum 

 Moss to one of peat. Raise them as high as possible above the rim of the pot, an essential 

 point in their cultivation. During winter these plants should be placed at the coolest end 

 of the East Indian house, but through the heat of summer the intermediate house is the 

 best position for them. At all times the supply of water must be constant, and give 

 them a position where they may be protected from sun-bine. Zygopetalum Mackayi, 

 Z. Sedeni, Z. crinitum, Z. rostratum, Z. brachypetalun, Z. Burkei, and Z. Clayi 

 should also be grown in pots, using about equal parts of peat and Moss and

a small quantity of rough loam and sand mixed well together for them to root in ; a well- 

 shaded position in the warm house will suit them. Z. maxillare Gautieri succeeds best 

 upon a piece of tree-fern stem ; it is a cool-growing species, and should be placed with 

 the Odontoglossums. Such deciduous epiphytal Orchids as Chysis bractescens, C. aurea, 

 C. Chelsoni, C. Sedeni, C. lsevis, and C. limminghej may be grown in teak-wood 

 baskets or shallow pans suspended close to the roof glass. As regards culture, 

 they require exactly the same kind of treatment as previously recommended for the deciduous 

 Dendrobes. Chysis generally bloom about March, and the flower spikes push up in con- 

 junction with the young growth. When the plants begin to grow, water should be sparingly 

 applied, but as soon as the flower spikes appear increase the quantity considerably. 

 Immediately the flowers fade, the young breaks commence to emit new roots, and this is the 

 best time to give more rooting space to plants that require it. Arundina bambusaefolia and 

 A. chinense (syn. A. Philippi) when properly grown and well flowered are very pretty.
