358 THE ORCHID REVIEW. [DrcEMBER, 1906. 
of persons, or from old generic names. Rules are also given for Latinising 
personal names. 
Hybrids are to be designated by a formula, and whenever it seems 
useful or necessary by a name, the formula to consist of the specific names 
of the two parents in alphabetical order, connected by the sign X. Whena 
name is given it is subject to the same rules as names of species, but is dis- 
tinguished by the addition of the sign “ X ” before the name. Forms and 
half-breeds among cultivated plants should receive fancy names in common 
language. 
Article 36 provides that on and after January 1, 1908, the publication of 
new names will be valid only when they are accompanied by a Latin 
diagnosis. 
Articles 48 and 49, refer to transfers of names, and it is provided (inter 
alia) that if a species is moved from one genus to another the original 
specific epithet should be retained, unless in the new position there remains 
some obstacle, as provided for in another section. Article 53, for example, 
provides that the specific name must be changed if it is already borne by a 
valid species in the new genus. We find this example given :—‘* Satyrium 
nigrum, L. Sp. Pl. ed. 1, 944 (1753), when placed in the genus Nigritella 
must be called Nigritella nigra, Reichb. f. Ic. Fl. Germ, et Helv. xiv. 102 
(1851), not Nigritella angustifolia, Rich. in Mem. Mus. Par. iv. 56 (1818).”” If, 
however, the transfer involves a change of rank (asa variety raised to the 
rank of a species, or the reverse) the earliest name in accordance with its 
new position must be retained. It is, however, recommended that the 
original epithet should be retained or re-established whenever possible. 
Article 51 remarks that ‘‘ Everyone should refuse to admit a name .. - 
when it is based on a monstrosity, or when it becomes a permanent source 
of confusion or error,”’ and the example is given :—‘‘ The genus Uropedium, 
Lindl., was based ona monstrosity which is now referred to Phragmopedilum 
caudatum, Rolfe.” 
Article 55 provides that ‘‘Specific names must be rejected . . . when 
they merely repeat the generic name,” and this gets rid of such absurdities 
as Corallorhiza Corallorhiza to designate the well-known Corallorhiza 
innata. 
Article 57 permits. the correction of any typographic or orthographic 
error, and thus Paphiopedilum Fairrieanum, not P. Fairieanum, is the 
correct name of'a now familiar species. 
Lastly, Article 58 states :—‘‘ The rules of botanical nomenclature can 
only be modified by competent persons at an international Congress con- 
vened for the express purpose. 
In an appendix we find recom mendations for the use of Latin or Latinised 
scientific names in preference to others, and for the use of the metric system.
