342 IHE ORCHID REVIEW. 
from natural species on the one hand, and from simple varieties on the other, 
to which end the sign of hybridity, x, should always be placed between the 
generic and specific names. 
2. Hybrids between species should receive a Latin specific name, one 
formed by combining the names of the two parent species being used by 
preference. Hybrids raised from the same two species, whether of inverted 
parentage or otherwise, should be considered as forms of one, and if necessary 
may be distinguished by the addition of a varietal name. 
3. Hybrids between genera should receive a generic name, formed by 
combining the names of the parent genera, reasonable abbreviation being 
permissible in certain cases. 
4. Secondary hybrids, 7.c., those in which one or both parents are them- 
selves of hybrid origin, should receive suitable vernacular or informal names, 
like florists’ flowers. 
_ A few explanatory remarks appear necessary on some of the points 
Taised :— 
ce Fhe sign of hybridity is of primary importance, and should never be 
omitted. The word hybridus,—a,—um, is objectionable for two reasons. It 
necessitates the use of three words instead of two, while a variety can only 
be distinguished by the addition of a fourth (e.g., Cypripedium hybridum 
Youngianum superbum, instead of C. x Youngianum superbum) ; besides 
which it is liable to be mistaken for a specific name. 
2. This rule is purposely drawn so that a simple or compound name may 
be used. The latter, though it expresses a great deal, is frequently too long 
for ordinary use, especially when a varietal name is added. A Latin word 
Should also be chosen, or at least one to which a varietal name can 
conveniently be attached, if necessary. Such a name, for example, is 
Cypripedium x Alice Should only be used for a secondary hybrid, or i 
florist’s sense, as a varietal name could not well be added. No distinction 
Should be made between natural and artificial hybrids, as a few take rank 
under both heads. And the attempt to distinguish those with reversed 
Parentage is impracticable, as the difference is also inappreciable, and 
Sometimes absolutely mil, as in Selenipedium x Sedeni, for instance. It is 
equally clear that in forming a compound name there is no need that either 
seed or pollen Parent shall uniformly have priority of place. In the case of 
natural hybrids it is impracticable, as well as in some artificial ones. And if 
insisted on it would often lead to two names for the same thing, as in the 
Selenipedium just mentioned. It is sufficient to know that Cypripedium 
* venusto-Spicerianum is derived from the two species whose name it bears. 
Hybridists should, however, carefully note the seed and pollen parents 2 
their hybrids, for which the sign and 7, respectively, will be found very 
convenient. Any important variation should be distinguished by the addition 
of a varietal name,
