been treated in the same way, where they could not conveniently be joined 
by a hyphen, but those consisting of a single word have been adopted. 
For the same reason Brassocattleya X Veitchii is preferred to the earlier 
B.-c. X Digbyano-Mossiz, which consists of seven syllables, and B.-c. X 
Marone to B.-c. X Madame Charles Maron, which consists of three 
distinct words. Names formed by joining the specific appellations of the 
two parents without abbreviation have generally been avoided, as too long, 
though this does not always apply. Further, such names have often been 
used in some particular sense. Thus we have Odontoglossum X _ crispo- 
Hallii and O. x Hallio-crispum, the latter being the reversed cross, but both 
are here included under O. X Cooksoni. Ina similar way O. x spectabile 
includes both O. xX crispo-Harryanum and O. X Harryano-crispum, 
Names formed by combining portions of the names of the parents have 
been adopted. 
2. PARENTS.—The names of the parents are given in their alphabetical 
sequence, and in most cases where the seed parent is definitely recorded 
the sign @ follows the name. But in many cases the record is not clear, 
and where doubt exists the sign has been omitted. Raisers might help to 
fill up some of these blanks, and to correct any that are known to be 
erroneous.

3. REFERENCES.—We have aimed at giving a reference to the original 
record in all cases, though the remark may not always apply to reports of 
the same meeting in different papers. The hybrids exhibited at meetings 
of the Royal Horticultural Society are taken from the Gardeners’ Chronicle, 
the records being continuous from the time of the epoch-making Calanthe 
x Dominyi. Those exhibited at meetings of the Société Nationale 
d’ Horticulture de France are mostly taken from the Society’s Fournal, 
though some of the records appear a little earlier in contemporary 
publications, which are also cited in many cases. The Orchid Review is cited 
regularly, so far as the first reference and any additional information is 
concerned. Owing to the appearance in the first volume of the “ History 
of Orchid Hybridisation,” and the continuous records since, the informa- 
tion is in a very available form. Other works are cited where the informa- 
tion found appears to be of sufficient importance. 
FicuREs.—Except in cases where they are unduly numerous, an attempt 
has been made to give a complete list of published figures, (avoiding, 
however, mere repetitions in the same work), and these are indicated by 
the letters ““t” and ‘“‘f.’ Any varietal names of the plants figured are 
given within brackets, immediately following the figure, as (v. oculata), 
(v. aureo-marginata), and (v. magnifica), which indicate varieties of Cattleya 
x Iris (p. 59). This point is mentioned, because it was found impractic- 
able to include the multitudinous varieties which have appeared within the
