. The Book of gardening; a handbook of horticulture. Gardening; Horticulture. ON ORCHIDS. 539 in perfection after expanding its flowers. The lovely D. formosum giganteum (Fig. 370) is one of the most beautiful and useful Orchids in cultivation, and its exquisite large white and yellow flowers being produced in the late summer and autumn months. Fig. 71.—Dendrobium thyrsiflorum. (when flowers of all description are scarce) adds further to its value. It requires highly humid and hot conditions during the period of growth, with the full benefit of the sun's rays. A fig or forcing- house suits it admirably. It should be suspended near the roof-glass. The evergreen section, to which D. thyrsiflorum (Fig. 371) belongs, is a lovely one, and may be grown under similar con- ditions to those suggested for trie deciduous section, with the exception that a little more warmth must be afforded during the resting period, or the foliage is liable to become spotted. There are numerous interesting varieties which flower through the summer months, and these are worthy of every consideration. Renanthera.—Owing to its shy-flowering qualities, this genus is not grown to any great extent. There are only three species which merit attention : R. coccinea, R. Storiei, and the dwarf- growing R. Imschootiana. These should be grown under similar conditions to those advised for Dendrobium, as they require strong light to flower satisfactorily. Peristeria and Phaius.—I have coupled these two genera as they require practically similar treatment. With the exception of Phaius tuberculosus, all are suitable for ordinary stove culture. The potting compost should consist of good fibrous peat and sphagnum, to which may be added a liberal mixture of turfy.
