larium, which takes after the latter in constitution 
while retaining much of the beauty of the former. 
Or again, Cypripedium Sanderianum, from the 
Malay Archipelago, needs such swampy heat as 
few even of its fellows appreciate; it has been 
crossed with Cy. znszgne, which will flourish any- 
where, and though the seedlings have not yet 
bloomed, there is no reasonable doubt that they 
will prove as useful and beautiful as in the other 
case. Cypripedium insigne, of the fine varieties, 
has been employed in a multitude of such in- 
stances. There is the striking Cy. hirsutissimum, 
with sepals of a nameless green, shaded yeilow, 
studded with spicule, exquisitely frilled, and 
tipped, by a contrast almost startling, with pale 
purple. Itis very “hot” in the first place, and, 
in the second, its appearance would be still more 
effective if some white could be introduced ; 
present it to Cyp. uzveum and confidently expect 
that the progeny will bear cooler treatment, 
whilst their “ dorsal sepal” will be blanched. So 
the charming Masdevalia Tovarensits, warm, 
white and lowly, will take to itself the qualities, 
in combination, of J7Zas, bella, tall, cool, and 
highly coloured red and yellow, as Mr. Cookson 
has proved; so Phalenopsis Wightiz, delicate of 
growth and small of flower, will become strong
