148 THE ORCHID REVIEW. [Mav, 1906 
not satisfied that it is not a Pescatorei cross, for it seems as near to. 
ardentissimum as to a spotted crispum, and although the hybrid just 
named was originally exhibited, with three others, without any indication 
of origin, we immediately recognised them as hybrids between O. crispum — 
and O. Pescatorei (See O. R., x., p. 210.). In this case, however, we 
have not seen a living flower. Mr. Crawshay describes the ground 
colour as white, and the blotching rich plum purple, the exterior edges 
of the blotches being a shade darker than the centre, and the markings 
of the lip bright brown. The spike bore five flowers, but we have 
omitted the lower one owing to considerations of size. The photograph 
is by Essenhigh, Corke & Co., Sevenoaks, and Mr. Crawshay remarks 
that the apical bloom is slightly exaggerated. The shape of the flower 
is excellent, and whatever the origin of the plant it is a very hand- 
some acquisition. It may be possible to clear up the doubtful point here- ; 
after, but we cannot help repeating the remark of a correspondent who has 
written to us upon this question, that we are getting too many of these 
hybrid Odontoglossums of doubtful origin. | 7 
CALENDAR OF OPERATIONS FOR MAY. 
By J. M. Brack, STREATHAM. 
Owine to the very great amount of sunshine that we have enjoyed during j 
the past month or six weeks, plants that have been disturbed by repotting 
have had every opportunity to re-establish themselves quickly. The large — 
amount of solar heat in the houses so early in the season has given things 4 
good start off, and everything seems pretty forward. It is not considered 
good practice to hasten things on too much with the advent of spring, for ; 
fear of forcing weak growth, but with plenty of light and the heat being 
natural, there is little fear of that happening this year. In any case, nO” 
reproach can be made for hastening growth this month, for now every 
encouragement should be given to it. I endorse the pretty general pracy 
tice of closing all ventilators, with the exception of the Odontoglossum 
house, about half-past three in the afternoon, admitting again at six o'clock : 
a chink of air by the bottom ventilators. Where, however, the house 5 
full of bloom, the closing of it might not be permissible, and should be post- 
poned until the flowering season is over. ue 
Cattleyas Mossiz, Mendelii, Schreedera:, and many Leelias and hybrids» 
are in bloom this month, and care must be taken not to get the blooms” 
spotted with damp. Ifit is desired to keep the flowers back for any PYF 
pose, it is best to group them at one end of the house, so that the syringe 
can be kept off them, and they can also have special protection given them
