EPIPHYLLUM CRUENTUM ACKERMANNI. 
The fine variety now figured was exhibited at the meeting of the Royal Botanic 
Society on May 19, and awarded a First-class Certificate of Merit. 
In regard to its origin Messrs. F. and A. Smith, of the Nurseries, West Dulwich (by 
whom it was exhibited), state that “ about fifteen years since we endeavoured by seeding 
to produce the colour of E. speciosissimum on E. Ackermanni major, which is of a red 
colour, and at the same time reduce the height at which the former grows before it flowers, 
and also with a view to getting rid of its spiny character. We were successful in getting 
several seedlings, more or less coloured with violet, but they were not free from spines, 
though having less in quantity. A further cross was made by using the white-flowered 
cruentum, which is entirely spineless, crossing it with one or two of the seedlings first 
raised ; the result was two with the colour of Speciosissimum, and spineless : ” one of these 
is the subject of our illustration. 
It is a distinct variety, fixed in character, and a decided advance ; the flowers large 
and of a brilliant scarlet colour, flushed with violet-purple. It will be distributed by 
Messrs. F. and A. Smith in due course.

CYPIIIPEDIUM STONE I PL AT YTiEN I U M . 
) 
The species C. Stonei is a native of Borneo, and flowered for the first time in the 
collection of J. Day, Esq., of Tottenham. It is to Mr. Day that we are indebted for the 
opportunity of figuring the handsome and superb variety which forms the subject of our 
illustration, with whom, also, it first flowered. The species produces dark green obtuse 
leaves, ten or twelve inches long, from the midst of which the scape ascends, bearing 
three flowers ; sepals large, white, streaked with dark purple, and tinged with yellow ; 
petals five inches long, yellow, streaked and blotched with purple ; lip large, purplish, 
with red veins. 
There are several varieties, and all worth growing, but the finest is Platytrenium, 
which is similar to C. Stonei, but has long straight broad petals, very handsomely spotted, 
as can be seen by a reference to the plate. 
Cypripediums succeed best in the East Indian House, and are generally free-growing 
plants, requiring plenty of pot-room, as they send out their thick fleshy roots very freely.
