CYPRIPEDIUM x PETRI AND VAR. BURBIDGEI. 
THE facts respecting Cypripedium Dayanum and C. virens, recorded at 
page 206, have thrown a totally new light on the origin of two curious 
plants described by Reichenbach, some fifteen or sixteen years ago, under 
‘the names of C. Petri and C. Burbidgei, but which have since been 
das synony with C. Dayanum, in spite of their undoubted 
differences. Before going further it will be advisable to reproduce 
* Reichenbach’s original remarks. 
C. Petri, Rchb. f., was thus described in 1880 (Gard. Chron., 1880, xiii., 
p. 680):—* This is very near Mr. Day’s Cypripedium, yet fresh materials 
just to hand confirms the first impression, which I wrote in February last 
to Mr. Harry Veitch, that it must be regarded as distinct. Its leaves have a 
darker ground colour, and just those far darker, squre green paintings 
which are so characteristic in the affinity, The whole flower is smaller, 
shorter. Sepals white with green veins, very distinct in outline, and much 
shorter than in the species I first dedicated to my most assiduous corres- 
pendent. Petals light brownish, green at base, ligulate, acute, straight or 
cuneate, acuminate, covered on the whole border with long hairs, just as in 
Cypripedium Dayanum. Lip greenish-brown, with dark sepia-brown on 
the front part of the disc, or totally of that colour, yet always, it would 
appear, with green angles. Warts on the border of involved base nearly 
purple. Staminode light green with some dark green veins. If there were 
not several other marks of distinction (in addition to the totally different 
colour of the flowers), it would be well distinguishable by the relative 
length of the sepals and petals. This is a discovery of Messrs. Peter Veitch 
and F. W. Burbidge, made in the Malayan Archipelago. It only bears ne 
fame of one of these gentlemen.” It is figured in Wien. Ill. Gart. Zeit., 
1894, p. 213, t. 2. 
C. Burbidgei, Rchb. f., was described in the following aiseat si 
-Chron., 1881, xvi., p. 38), as follows:—‘ Much in the way of Cypripedium 
Javanicum, Reinw., and C. virens, Rchb. f., but very easily distinguishable 
by the staminode, which is quite abrupt in front, and with three exceedingly 
obscure teeth. The lip is more conical than in any species of the papi 
quoted, resembling that of C. Petri and C. Dayanum. Petals light green, 
with a row of most obscure dark warts on each side, and one on the middle 
line, and some mauve on the lip’s margins. The upper sepal is almost 
triangular, as in C. purpuratum, with nine green nerves. Rue Iepen penal 
is very small and short. Leaves nearly those of C. javanicum. My first 
“acquaintance with this was undoubtedly made by alte assistance A 
t. S. Low, who pointed out the affinity with C. javanicum, when T ace 
that with C. virens, though the petals are too much bent down. It was a
