with Roman characters, the use of Latin being only authorised when it 
expresses the character or quality of the plant, as nanus, albus, maculatus, 
or when it harmonises with a descriptive specific name, as Cypripedium 
nitens var. Wrigleyi. In all other cases classical or vernacular names 
should be used. They should be expressed as far as possible in a single 
word, but the employment of not more than three words is permitted as a 
maximum. Such names should not be translated when transferred to 
another language. 
(k) HyBRIDS DESCRIBED as SPECIES.—Hypbrids that were originally 
described as species should be transferred as soon as their real status is 
discovered, and the sign x should be placed before the specific name, or 
of the oldest name when more than one name has been used. 
(i) TRANSFERS.—When the parents of a hybrid are transferred to 
another genus the name of the hybrid follows, and is subject to the rules of 
priority or others applicable to species under similar conditions. 
(k) PusticaTion.—A new hybrid is considered published when a name 
is given in accordance with the rules, together with the formula of parentage 
and a short description or figure, and is recorded in some work or periodical 
that is sold or circulated in the usual way. Descriptions may be drawn up 
either in English, French, German, Italian, or Latin. Publication in a 
dated horticultural catalogue is valid, but it is desirable that it should also 
be published in periodical horticultural journals. The exhibition of a 
hybrid at a horticultural meeting does not secure publication unless also 
properly recorded. R. A. ROLFE. 
There are three serious discrepancies between the Vienna and Brussels 
tules which it-is desirable should be eliminated :— 
(1) The Vienna Rules provide that the specific name of a hybrid shall 
be subject to the same rules as names of species, and the modification made 
at Brussels that they should come under the rule for varieties—which 
‘permits the use of three words as a maximum—destroys the simplicity 
of the Linnean binomial system amd gives rise to all manner of in- 
consistencies. 
(2) The provision that in the formula the names of the parents shall be 
given alphabetically eliminates the element of uncertainty, for the seed 
parent is unknown in the case of natural hybrids, and in many of those 
raised artificially, while many others have been raised both ways. 
(3) The provision in the Vienna Rules that generic hybrids shall be 
referred to the parent genus that comes first in the alphabetical series 
would refer certain hybrids to a genus to which structurally they do not 
belong, as Epicattleya and Chondropetalum, while the limits of many 
natural genera would be completely obscured. It is quite unworkable.
