J 76 THE ORCHID REVIEW. [December, 192 r. 
known for many years past, and several beautiful results may be seen in 
•hybrids derived from them, although in no previous case did the system 
of spotting change to blotches. O. Armstrongii shows a great advance 
<in this respect, and constitutes the finest example yet seen in this 
section, for large and definite yellow blotches on the petals take the 
place of the irregular spotting that occurs in its predecessors. We are 
indebted to the Editors of the Gardeners' Chronicle for their kindness in 
lending this block. 
CATTLEYA HYBRIDS. 
C HE new edition of Sanders’ List of Orchid Hybrids shows in a marked 
way the great increase-that has taken place in recent years in the 
various hybrids. Taking the Cattleyas only, the List enumerates about 
•700 different crosses, and this does not include any of the Cattleya 
•combinations, such as Laeliocattleya and Brassocattleya, etc. Since the 
previous edition, which, with the Addenda, brought the records up to the 
end of 1916, about no new Cattleya hybrids have been recorded. 
A rough analysis of the parentages of these no hybrids shows that C. 
Dowiana and C. aurea have taken a share in the making of no less than 68 
•of this total. No other species comes anywhere near this high figure. If 
-we seek for the reason, it is found in the numerous splendid hybrids that 
have been produced in previous years by one or the other of these plants. 
The latest results show an even greater proportion, and doubtless there is a 
multitude of C. aurea hybrids fast approachiug the flowering stage that will 
;be recorded within the next few years. 
It is by no means easy to place these hybrids in any particular 
•classification. Two sections, however, stand out prominently: one 
• containing the combination of C. aurea with the large purple species, 
and of which examples may be seen in Fabia, Hardyana, and Empress 
Frederick; the other comprising C. aurea in conjunction with the 
yellow flowering plants, as witnessed in Iris, Sibyl, and Venus. In the 
former section large flowers of bright purple tints are produced, while 
in the latter medium-sized flowers of yellow, bronze-yellow, and golden- 
yellow are mainly seen. 
About twenty of the hybrids recorded since 1916 are the result of 
crossing albino varieties of species and hybrids. Noteworthy examples are 
<C. Annette (chocoensis alba X Warscewiczii F. M. Beyrodt), C. Bronacha 
(Gaskelliana alba X Mrs. M. Peeters), C. Celia (Harrisoniana alba X Lady 
-Veitch), C. May Queen (Astron X intertexta alba), C. Muriel (Mendelii 
alba x Dusseldorfei Undine), and C. Snowdrift (chocoensis alba X 
iDusseldorfei Undine).
