TKEATMENT OF EPIPHYTAL OKCIIIDS. 27 



30. Dendrohium chrysanthum. — A fine Indian species, which 

 flowers in February, March, and April ; the colour deep yellow, 

 with a dark red lip. It may either be grown in a basket sus- 

 pended from the roof, or in a w^ell-drained pot filled with fibry 

 peat and half-decayed leaves, with plenty of heat and moisture 

 during the growing season ; afterwards it should be kept nearly 

 dry and very cool. Its flowers only remain a short time in 

 perfection. 



31. Dendrohium Dalhousieanum. — This charming species 

 comes from India, and flowers in March and April ; the blos- 

 soms are very large, seven or eight together in a bunch, pale 

 lemon, with a pink margin, and two dark, blood-coloured spots 

 in the centre. It succeeds best in a well-drained pot, filled 

 with fibry peat and half-decayed leaves ; it likes plenty of heat 

 and moisture when in a growing state. Its flowers only remain 

 a short time in perfection ; it resembles D. cupreum, 



32. Dendrohium cuciillatum. — A pretty plant, which, like the 

 preceding, comes from India ; it flowers profusely in IMarch and 

 April on the leafless stems of the preceding season ; the blos- 

 soms are light rose and pale lemon. It does best in fibry peat in 

 a basket suspended from the roof, and, when in a growing state, 

 requires less heat and moisture than any of the preceding kinds ; 

 but afterwards it should be kept rather dry and cool. Its 

 flowers, which are scentless, remain long in perfection. 



33. Coryanthes macrantha. — This extraordinary plant comes 

 from the Caraccas ; it flowers in June, the blossoms being 

 extremely large, two or three together, on a pendulous scape ; 

 tlie lip is blood-red, the rest orange yellow, spotted irregularly 

 with dull purple. It succeeds best on a block, surrounded by 

 fibry peat, and suspended from the roof; it likes plenty of light, 

 and little moisture, and should be kept rather w^arm, except 

 in the growing season, when a pretty liberal supply of moisture 

 and strong heat should be given ; overmuch moisture at any 

 other time is fatal to the plant. Its enormous flowers only 

 remain in perfection two or three days ; tliey emit a rather 

 strong odour ; this is the most singular of all Orchids. 



34. Sohralia macrantha comes from Guatemala, and flowers 

 in July and August ; the flowers, rosy purple and crimson, are 

 very large, and are produced one after another in succession from 

 the tops of the long reed-like stems. It does best in a large pot 

 in fibry peat, leaf-mould, and a small portion of well-decomposed 

 cow-dung ; it likes bright light, and but a moderate amount of
