[March, 
soil), and they were placed in small, well-drained pots, filled up in the usual 
manner with good fibrous sandy peat. To prevent them from flagging, they 
were placed under hand-glasses in a warm house on a bed of gravel, under 
which a hot-water pipe passes, and where by sprinkling the gravel inside the glasses 
an abundance of humidity was ensured. At first the glasses were kept very 
close, a little air being left on during the night only. They were frequently 
sprinkled overhead, and the stems thoroughly saturated with water either by 
dipping them in a tank or by means of a sponge, inclining them to one side, and 
repeatedly pressing the contents of the filled sponge over the stems. Under 
this treatment they soon made an abundance of new roots, when they were 
gradually inured to the air of the house, but the stems were still saturated 
several times daily; meanwhile the roots fast permeated the peat, moss, and 
twigs, many coming to the outside, when they received another coating of moss, 
and this was continued until they reached the soil in the pot; after a suffi¬ 
cient quantity had done this, the watering of the stems was gradually discon¬ 
tinued, and the plants made to depend entirely on the soil in the pot for their 
nourishment. As by the continual wetting the soil had become somewhat soddened, 
all that could be conveniently removed was replaced by fresh earth, and after the 
lapse of a few weeks the plants were shifted into pots a size larger. They now 
occupy 4-in. and 6-in. pots, and the stems measure from 6 in. to 9 in. in 
circumference. 
I may add that we put a few plants of the hardy Lcistrea Filix-mas cristata 
on short stems in the same way, but giving them less heat during the rooting 
process. They have a handsome appearance, but I have no doubt would require 
some slight protection about the stems during very sharp weather, especially if 
planted in exposed situations.— Thomas Winkworth, Holkham Gardens. 
CYPRIPEDIUM HARRISIANUM. 
^NE of the beautiful hybrid orchids for which the lovers of choice flowers 
have to thank Mr. Dominy, and which is named after Dr. Harris, of Exeter, 
to whom Mr. Dominy thus acknowledges his obligations for some of his 
earliest teachings on the subject of hybridizing orchidaceous plants. For 
the figure we are indebted to the Messrs. Veitch and Sons, of Chelsea, by whom 
the plant is now being distributed. 
This hybrid Lady’s Slipper, which is a cross between Cypripedium barbatum 
and C. villosum , the latter having been the mother plant, is fully described by 
Professor Reiclienbach in the Gardeners' Chronicle. The leaves are ligulate, 
narrower than those of barbatum, broader than those of villosum, tridentate 
at the apex, glossy, the surface tesselated with dark green. The peduncle is 
hairy, bearing flowers as large as in the largest forms of C. barbatum. The 
upper sepal is broad, very glossy, with confluent atroviolaceous streaks, so that it 
appears of a blackish-purple, whitish only near the top ; the petals spread at
