normal for any particular plant group, is a basic prerequisite for a rational 
and scientific development of superior strains in new crosses. Work in the 
leading Cattleya family has so far lagged behind because of specific technical 
difficulties. We have been pioneering in this field since World War I. Our 
purpose is to develop vastly improved and consistently uniform crosses in 
terms of plant vigor and productivity as well as size, color, texture and 
keeping qualities of the blossom. 
FOREWORD 
It is sincerely believed that all basic information needed to 
evaluate the main characteristics of the parents listed herein can be supplied 
precisely and to-the-point without undue redundance. For purposes of 
clearness and brevity, where feasible, each main class of the following 
crosses is subtitled with a comprehensive, though conservative, set of care- 
fully checked characters found to hold true for all parents in that class. 
Concurrently, and advisedly, the wording of individual descriptions has 
been kept within very few essential terms. So it is with reference to the 
flowering season, a complement endowed with a considerable degree of 
pliability. Of course, should further clarification on any of these points be 
desired, please ask for it in writing. 
Please note that the majority of parent. plants herein listed are 
the recipients of one or more Awards of Honor. Others, equally worthy 
in every respect, have not as yet been exhibited or entered into competition. 
Also, please notice the complete listing here, for the first time anywhere, 
of the chromosomal assessment for each parent. The identity of color, when 
specified, is in accordance with Ridgway’s Color Standards and Color No- 
menclature.
