Ehododendeon indicum album and Coelogyne cristata alba. 



The kindness of two of our Fellows enables us to reproduce illus- 

 trations of two examples of excellent cultivation, one in the open, 

 the other under glass. 



The former represents Rhododendron indicum album (= Azalea 

 indica alba) in the garden of Austin Mackenzie, Esq., of Canadale, 

 Argyllshire. It is a bush 5 feet 6 inches in height, and with a diameter 

 of 15 feet 6 inches. It flowers profusely every year (fig. 107). 



The latter, illustrating Coelogyne cristala alba, was sent by Lieut.- 

 Col. H. Powys Greenwood, of Whitsbury House, Salisbury, who also 

 contributes the following notes: — 



" This plant of Coelogyne cristata alba was bought from Mr. Bull 

 of Chelsea in 1891, a small plant with two leads in a six-inch basket. 

 It now occupies more than a square yard of space, and was this year 

 (1911) covered with spikes, many of them having six flowers, evenly 

 distributed over the surface. 



" The Albino variety of C. cristata must be one of the purest 



i white flowers known, and this whiteness is greatly enhanced" by con- 



1 trast with the intensely deep green of the leaves. 



' ' The culture of this Orchid is so well known that it calls for little 

 remark; it should be kept in the cool house, and, although some 

 growers advocate taking it into the intermediate house for a few weeks 

 before the flowers open, I have never found it necessary. It delights 

 in plenty of water during growth, to which the occasional addition of 



j a little weak liquid manure is a great benefit, causing the pseudo-bulbs 

 to swell well, and giving to the leaves that dark, rich colour which 

 contrasts so delightfully with the purity of the flowers. When in 

 bloom the plant may be brought into the drawing-room or hall, and will 

 last from a fortnight to three weeks in perfection, the rest thus 



i obtained being a benefit rather than the reverse " (fig. 108).
