combination are easily recognisable. It is followed by the sign x, and a 
specific name (f). The name is written as a single word, and without a 
hyphen. Abbreviation is necessary except in the case of short words. 
Examples: Leliocattleya (Cattleya x Lelia), Sophrocattleya (Cattleya x 
Sophronitis), Odontioda (Cochlioda x Odontoglossum). . 
(c) MULTIGENERIC HYBRIDS receive a conventional generic i 
preferably that of a distinguished man, to which is added the termination 
ara. A distinct name is required for each different combination of genera, 
and all combinations between them, in whatever way _ intercrossed, 
will bear the same name. Examples: Vuylstekeara (Miltonioda x 
Cochlioda), Lowiara (Brassolzlia x Sophronitis). As an exception, the 
names of the trigeneric hybrids, Brassocatlelia and Sophrocatleelia, already 
in use, are retained. The generic name is followed by the sign X, and @ 3 
specific name (/). : 
(d) SECONDARY AND MORE COMPLEX HYBRIDS.— Hybrids (when fertile) 
recrossed with their parents or with other species or hybrids give rise to 
secondary or more complex hybrids, and are dealt with under the he 
rule as primary hybrids (a), forms derived from the same combination 
receiving the same specific name (f), and variations being indicated by 
varietal names (g). 
N.B.—This rule may have to be subsequently modified. Secondaty 
hybrids of identical specific composition may be obtained in different ways 
For example, a hybrid containing Cypripedium barbatum (1), insigne (2); 
Spicerianum (3), and villosum (4), can be obtained by crossing either C. Xx 
Ashburtoniz (1 X 2) with C. x Lathamianum (3 x 4), ©. X By ermanianum 
(I X 3) with C. x nitens (2 x 4), or C. X Harrisianum (1 X 4) with C. 
xX Leeanum (2 X 3). It is this fact and the increased amount al 
segregation seen among secondary hybrids that proclaims their wee 
distinctness as a class from primary hybrids. It is probable that natur 
hybrids which show a large preponderance of one of the specific ai 
are in many cases recrosses with that parent, as the phenomenon 1s Wé 
know among artificial hybrids). 
(e) FORMULA OF PARENTAGE.—The formula consists of the names of the 
two parents in alphabetical order, connected with the sign x and placed 
between brackets. When the hybrid is of known experimental origin a 
formula should be made more precise by the addition of the sign ? after as 
name of the seed-bearing parent. ' : 
(f) SPECIFIC NAMES OF HYBRIDS.—The specific name of a hybrid may 
be expressed in Latin or in any language that is written in mae 
characters. It should consist of a single word or of two short words tha 
can be connected by a hyphen. eH 3 
(g) VARIETAL NAMES OF HYBRIDS must be written in some languas®
