| of amateurs to the wonderful series of new forms of Odontoglossum 
# which have been recently introduced by the Brussels Horricutture 
INTERNATIONALE, and by Messrs. Lucren LinpEN et C2, Moortebeek, several of. 
which have obtained the highest awards at the different Exhibitions. held last 
Spring. It has been decided by the Editor of the Lindenia to devote an extra 
number to some of the most remarkable amongst them. 
O. x rubiginosum, which must be placed foremost on the list, is well worthy 
of its place, as may be seen by our plate. In form the flowers are almost like 
those of a very broad form of O. x Wilckeanuwm, but much deeper in colour. The 
sepals are broadly-lanceolate, acuminate, the edges are rather wavy, of a light 
yellow, which changes to white towards the base, ornamented with very large 
irregular chocolate-brown blotches. The petals are of the same colour as the 
sepals, but notably broader, acute or shortly acuminate, margins irregularly 
denticulate-lobate, with a very large irregular blotch above the centre and four 
or five smaller ones towards the base. The lip is narrowly obovate, shortly 
acuminate, edges wavy and rather ragged, with a large irregular blotch and others 
smaller of a lighter brown than those on the sepals; towards the base there are 
numberless short, diverging lines of the same colour. The column is yellowish- 
white, somewhat blotched with reddish-brown. 
According to M. Lucien Linpen, this fine plant is most probably a natural 
hybrid between O. crispum and O. sceptrum and we believe this opinion to be 
well founded. We may here remark that O. sceptrum, which is considered by 
M. Linven as being a distinct specific type (Les Orchid. exot., p. 866), is classed 
by other authors as being simply a variety of O. luteo-burpureum. Whereas the 
latter, crossed with O. crispum, has produced O. Wilckeanum, which bears great 
analogy to our plant, but is however clearly distinct. 
On the other hand, the cross of the two species O. crispum and O. sceptrum, 
_ has already produced O. Harvengtense L. Linp., figured in the preceding volume 
of the Lindenia (X, pl. 478). It suffices to compare the plates 478 and 517 to see
