SEPTEMBER, 1916.] THE ORCHID REVIEW. 215 
habit combined with solitary flowers of good size and rich purple colour, 
which differences are reflected in the hybrids, which are as follows :— 
L. pumila. Le. Clive. Le. Jessica. 
L. Dayana. Le. Ingramii. Le. auro-Ingramii. 
Now follows a species with very marked habit, and an elongated scape 
of comparatively small flowers, with a narrow three-lobed, and much- 
crisped lip, the colour in the only one from which both the primary and 
secondary hybrids with C. Dowiana have been raised being rich cinnabar- 
orange. The latter colour and the narrow lip are dominant characters, so 
that further crossing with C. Dowiana is desirable. 
CROSSES WITH BRASSAVOLA. 
Of the genus Brassavola the popular B. Digbyana is the only one from 
which both the primary and secondary hybrids have been raised, and in 
both cases the colour of the Cattleya parent is dominant. These hybrid 
Brassocattleyas are very handsome, and further crossing with C. Dowiana 
would probably accentuate the yellow colour, though at the same time 
reducing the depth of the lip’s fringe. The following is the series :— 
_B. Digbyana. Bc. Leemaniz. Bc. Minerva. 
fe | CROSSES WITH SOPHRONITIS. 
Lastly comes the dwarf and brilliantly-coloured Sophronitis grandiflora, 
which, when united with C. Dowiana, has given primary and secondary 
Sophrocattleyas of great brilliancy, in both the colour of the Sophronitis 
being dominant. They are as follows :— 
S. grandiflora. Sc. Doris. Sc. Dorea. 
Here we find a varied series of nineteen secondary hybrids in which the 
beautiful Cattleya Dowiana is twice represented, and which in consequence 
would be expected to show a preponderance of its own essential characters, 
yet in very few cases is the yellow colour of the sepals and petals repro- 
duced, and those for the most part where purple was originally absent. It 
is probably a case of reversion, for C.. Dowiana stands alone in the C. 
labiata section for its yellow colour, and thus was probably derived from a 
purple ancestry, a theory which is confirmed by the presence of a flush of 
purple in the petals of many of its forms. White varieties of purple species 
scarcely forms an exception so far as the yellow colour is concerned, though 
the behaviour of the yellow Lzlia tenebrosa Walton Grange var. suggests 
that the few forms with the latter colour could be utilised in the attempt to 
raise a race of yellow Cattleyas. Of the species having this colour one is 
practically limited to Lzlia xanthina, which is weak in other respects, for 
Leia flava and L. Cowanii are too small, though the primary hybrids with 
C. Dowiana, known as Lc. Andromeda and Le. Ariel respectively, are 
probably being followed up. 
It is an instructive series, and affords interesting evidence on the
