108 THE ORCHID REVIEW. [APRIL, 1909. 
prettily blotched with dark purple. This cross might be repeated, to see 
whether the Pescatorei influence would not come out better another time. 
O. crispum X Vuylstekei has a white ground colour, with very large reddish 
claret blotches on all the segments, while the white margin and tips, and a 
pure white area at the base of each segment, gives the flower a very bright 
and attractive appearance. A seedling O. X amabile, has broad, very 
acuminate cream-white segments, with many small chestnut red spots on the 
petals, larger blotches on the sepals, and a crescent-shaped blotch in front 
of the yellow crest of the lip. A seedling of O. X waltonense has a light 
yellow ground colour, with several chestnut brown spots on the sepals, and 
a large blotch on the lip. A seedling of O. crispum has good broad rosy 
sepals and petals, with a red-purple blotch in the centre of each, those on 
the petals being crescent-shaped. The remaining one is an inflorescence of 
O. odoratum, having bright yellow, very acuminate segments, much spotted | 
with red brown. It isa Venezuelan species, and is quite distinct from O. 
gloriosum, which has sometimes been confused with it, under the same 
name. 
CALENDAR OF OPERATIONS FOR APRIL.

CATTLEYAS AND LaLias.—Many of the early-flowering varieties will need 
repotting or top-dressing this month, and this should be seen to as soon as 
they commence to root, for, if left too long, many of the young roots will be 
broken, and growth will be checked. Great care should be taken in turning 
the plants out of the pots, and in most cases the pots will have to be 
smashed, and the pieces carefully removed from the roots. The old material 
must be carefully picked out, and if at all sour the roots will be better 
washed in tepid water. In repotting good sound fern or Osmunda 
fibre should be used, and this should be carefully worked in between the 
roots, and not just crushed down in the pots. If the plants are well rooted 
there should be enough roots to fill the pots when spread out. _ Pot firmly, 
and keep the material about half an inch below the rim of the pots. Plants 
that have not been disturbed for some time will have several old bulbs — 
which are of no use to the plants, and these should be removed, and can be 
used for propagating. The plants must be firmly staked or made fast in 
some way, as if allowed to move about the young roots soon get broken, and 
then they will be more of an eyesore than a success. Back bulbs which are 
required for propagating must, of course, have a good, sound eye, and thus 
should be removed with a piece of the rhizome attached. They should be 
placed in pots filled with crocks and topped with a little moss, and 
placed in a frame where a good heat can be kept. 
In making up specimen plants the back bulbs should also be removed,
