dance with the best practice for coining such names. Here is where
the Code will help him. In it he will find (under Section F) a series of
rules for his guidance, based on the accumulated experience of
horticulturists of many nations. I will not repeat these rules
here--they can be read in the Code--but perhaps the most important,
apart from the rule already quoted that the name must not be in Latin,
is that it should be short (not more than two words), should avoid forms
of address liable to be confused (_e.g._ Mr., Mrs. and Miss) and, as far
as possible, should be easily pronounceable by all nationalities. As the
Code says, 'Centenaire de Rozain-Bourcharlat,'
'Diplomagartenbauinspektor,' and 'Eldwyth Cholmondeley' are not looked
upon with favour as cultivar-names! Having chosen a name, it is
essential to ensure that it is published, together with an adequate
description, since the Code does not recognize names that are not
published, or are published with no description. The Code lays down what
is meant by publication, and by adequate description. The names of
plants which receive an Award at Vincent Square are automatically
published, with a description, in this JOURNAL, but for other methods of
publication the Code should be consulted.

_Hybrids_

The naming of cultivars derived from crosses between two or more
different species, belonging to the same or different genera, involves
rather special problems. By "derived from" I mean not only the _first_
generation from a species cross, but all subsequent generations and
back-crosses with the original parents or with members of the first or
later generations. Any cultivar which is the progeny of a species cross,
however remote, comes, for the purpose of the Code, under the heading of
a hybrid and its naming is subject to definite rules. The full name of a
"hybrid cultivar" must be regarded as consisting of three distinct
parts: (1) the name of the genus (or "hybrid genus" if a hybrid between
two or more genera is concerned); (2) a "collective" name or phrase
covering _all_ the progeny resulting from the particular species-cross
concerned; and (3) a cultivar-name for the particular form (cultivar)
under consideration. In the name _Viburnum_ x _bodnantense_ 'Dawn,'
_Viburnum_ is the generic name, x _bodnantense_ is the collective name
for all progeny of the cross _V. fragans_ x _V. grandiflorum_, and
'Dawn' is the cultivar-name for a particular seedling of this
