130 THE ORCHID REVIEW. [May, 1911. 
is something that is added to a specific name to indicate a departure from 
type, as Cattleya intermedia alba, the white variety of Cattleya intermedia, 
C. Dowiana Mrs. F. Hardy, Mrs. F. Hardy’s variety of C. Dowiana. The 
name of a hybrid is something quite different. It is not a varietal, but a 
specific name, to which varietal names must almost inevitably be added, for 
hybrids are notoriously variable. If the binomial rule is followed for the 
specific name all is perfectly clear, as Cattleya Hardyana, which has 
innumerable varieties—for example, C. H. alba and C. H. Countess of 
Derby. But if the binomial rule is not followed for the specific name, we 
get a complication, for example C. William Murray and C. William 
Murray fulgens; C. Miss Harris .and C. Miss Harris var. E. Ashworth, 
which latter the Gardeners’ Magazine once termed ‘‘a somewhat lengthy and 
incongruous name.” 
Article 4 should be limited to varieties and to plants named as florists’ 
flowers. Primary hybrids should certainly be excluded, and indeed all names 
that are used in a specific sense. In these cases the name should be limited to 
asingle word, so that any necessary varietal names can afterwards be added. 
We shall strongly contend for this interpretation of the rules, and here we 
will leave the matter for the present. 
HORTICULTURAL NOMENCLATURE. 
Ru es of Horticultural Nomenclature adopted by the Nomenclature Sub- 
section of the International Congress of Horticulture, held at Brussels in 
Iglo :— 
Article 1.—Horticultural Nomenclature is based on the Rules of 
Botanical Nomenclature adopted by the International Botanical Congress 
held at Vienna in 1905. It adopts all its principles and rules as regards 
names of species and groups of higher rank, with the modifications and 
additions contained in the following articles for horticultural varieties and 
hybrids of cultivated plants. : 
Among the principles which serve as the basis of theSe rules it is 
particularly important not to lose sight of the following :— 
1. The essential points in nomenclature are: a, to aim at fixity of 
names ; ), to avoid or to reject the use of forms or names which may cause 
error or ambiguity, or which throw science into confusion. Next in 
importance is the avoidance of all useless creation of names. Other 
considerations, such as absolute grammatical correctness, regularity oF 
euphony of names, prevailing custom, respect for persons, &c., notwith- 
standing their undeniable importance, are relatively accessory, 
2. No custom contrary to rule can be upheld if it leads to confusion or 
error. When acustom offers no serious inconvenience of this kind it may
