356 THE ORCHID REVIEW. 
purchased as C. Bungerothii. Then one flowered with Messrs. Hugh Low 
and Co., at Clapton, which had been obtained as C. Bungerothii, though on 
flowering it presented two or three anomalous features, which led them to 
suspect that it was a natural hybrid between that species and C. macrocarpum. 
Almost immediately afterwards came the remarkable group exhibited by 
Messrs. Linden, L’Horticulture Internationale, Brussels, at the meeting of 
the Royal Horticultural Society, on November 13th, to which a Silver 
Banksian Medal was awarded. Besides examples to the two species just 
named, it included a series of curiously intermediate forms, which are 
evidently natural hybrids between the two species named, which have long 
been known to grow in the same district. The new material adds an addi- 
tional chapter to the history of this remarkable genus. The plants were 
exhibited under four different names, but I believe all, including those men- 
tioned above, have originated from the same parentage, and thus may be 
considered as varieties of one hybrid, for which the name of C. x splendens, 
Cogn., may be retained, the others being placed as varieties of it. 
C. x splendens has flowers approaching C. Bungerothii, both in form 
and colour, but a little smaller, the spur rather more conical, deep yellow 
inside, and a trace of the thick callus in front of the lip, which is so cha- 
racteristic of C.macrocarpum. C. x s. viride has the flowers slightly 
flushed with pale green, and the callus a little more developed. C. x s. 
regale is near the preceding, but has a trace of purple marbling at the base 
of the petals, while the inside of the lip is marbled and partially suffused 
with red-purple. C. x s. aurantiacum has deep yellow flowers, with a few 
small purple spots on the sepals and petals, the structure being similar to 
that of the typical form. 
C. x s. Luciani (exhibited as C. Luciani) has the lip much like C. 
Bungerothii, but the sepals and petals approaching C. macrocarpum, both 
in shape and colour. 
C. x s. maculatum (exhibited as C. Lindeni) has the sepals and petals 
densely and beautifully spotted with red-purple, arranged somewhat in 
transverse lines, and a lip closely resembling C. Bungerothii. Thus it 
almost combines the lip of one parent with the sepals and petals of the 
other. A succeeding variety explains why the name is changed. 
C. x s. O’Brienianum (exhibited as C. O’Brienianum) has the sepals and 
petals almost identical with C. x s. Luciani, and the lip ivory-white, but 
galeate, with the mouth only an inch across, and with denticulate margin ; 
thus approaching C. macrocarpum in shape. 
- x s, Lindeni(C. macrocarpum var. Lindeni, O’Brien in Gard. Chron., 
1894, li. p. 306 ; Fourn. des Orch., v. pp. 205, 206, fig. 76; Lindenia, x. p24, 
t. 442) has the sepals and petals of C. macrocarpum, but the lip intermediate 
in shape, one and a half inches broad, somewhat three-lobed, and with well 
developed callus, the colour being yellow, with the basal half, and a forward.
