THE ORCHID WORLD. 



batch of Sobralia macrantha alba seedlings 

 grow with vig'our ; those which have flowered 

 are all pure white. The small seedling pots 

 are buried in a bed of moss ; this method 

 prevents a too rapid evaporation of the 

 moisture in the compost. 



A similar house is entirely filled with 

 larger seedlings, many of them strong 

 enough to flower this season. The growth 

 and habit of the primary hybrids allows one 

 to detect in man}- of them the parents which 

 have been used, but m the case of the 



and C. Leeanum are grown on account of 

 their flowers proving of great utility for 

 decorative purposes. 



The collection of Cypnpedium hybrids 

 embraces most of the noted plants, those 

 finding special favour being : Thalia Mrs. 

 Francis Wellesley, Gaston Bulteel and 

 Germain Opoix. There is an interesting 

 batch of albinos, and several of the best 

 bellatulum crosses. 



The Miltonias are a special favourite with 

 M. Dietrich, so much so that a whole house

secondary hybrids this detection is almost 

 impossible. 



The Cypripedium hybrids occupy the 

 greater part of another spacious house. The 

 majority of these plants are unflowered, and 

 considerable interest is taken in watching 

 the development of the flower buds. The 

 exhibition standard of these hybrids is very 

 high, and a large number have to be flowered 

 before a really good one is secured. 

 M. Dietrich has, so far, obtained more than 

 the average amount of success. A number of 

 large plants of Cypripedium Lawrenceanum 



IS devoted to their culture ; and it should be 

 also said that the method of culture is suitable 

 to this genus, for there are hardly any spots 

 to be seen on the leaves. There are more 

 than 500 large plants, and the varieties are 

 so numerous that only the following very 

 special ones can be mentioned : Val 

 Duchesse, Empress Augusta Victoria, of an 

 uncommon deep rosy-purple tint. Queen 

 Alexandra, the handsome Leopoldii, and 

 Vuylstekeana. An interesting seed-pod is 

 Miltonia Bluntii x Miltonia vexillaria. The 

 scarlet flowering Miltonioda Harwoodii, a
