ODONTOGLOSSUM (HYBRIDUM) CORADINEI ees. ¢ 
A natural hybrid, evidently derived from Odontoglossum crispum and O. Lindleyanum, between which species it is thoroughly intermediate in 
character. Among the numerous individuals which have from time to time appeared a considerable amount of variation exists, both with regard to shape 
and colour, but in all cases characters of one or both parents may be readily observed. More especially is this the case with O. Lindleyanum ; the narrow 
segments of this species, the narrow, long-stalked lip, with its two characteristic calli, and the elongated column, with its entire wings, have all lent their 
peculiar character to O. Coradinei. On the other hand, nearly all the parts of the flower of this hybrid are modified in the direction of O. crispum, the other 
parent. Some of the forms have a nearly white ground, as in this species, though the majority have more of the yellow of O. Lindleyanum. Some forms are 
conspicuously blotched with cinnamon-brown, while in others the spots are very small, and occasionally nearly absent.

Odontoglossum Coradinei originally appeared in a batch of O. crispum imported by Messrs. James Veitch & Sons, of Chelsea. It was described by 
Prof. Reichenbach in 1872, that author supposing it to be a natural hybrid between O, triumphans and some species of the group of O, odoratum—a supposi- 
tion, however, which is hardly in accordance with the characters of the hybrid. Several other specimens soon afterwards came to light, differing more or less 
from the original type, and several years later it was suggested that O. Lindleyanum and O. crispum were the parents ; of which there now appears to be 
not the slightest doubt. I am a little suspicious as to whether all the plants which have been called Coradinei really have the same parentage as the original 
specimen, though at present there is no direct proof to the contrary. If all are correct the hybrid is an extremely variable one. The Orchid Album figure 
has the column and stalk of the lip shorter than usual, if it really belongs here ; while the variety Kinlesideanum, which is said to have been imported with 
O. Pescatorei, might well be a hybrid between that species and O. triumphans, according to the description, and thus a variety of O. excellens. Examination 
of a specimen alone can decide the point. The.variety hemileurum has the sepals and petals white, blotched with cinnamon, and the lip wholly yellow. Var. 
Kinlesideanum is said to have the sepals and petals white, bordered with yellow ; while var. albidulum is also described as having yellowish-white flowers, 
with some light sulphur at the base of the lip. Var. grandiflorum recalls O. excellens in its colouring. If the original specimens from which these varieties 
were described are still in existence a few flowers would be most acceptable for preservation at Kew, where already over a dozen different specimens are 
preserved, no two of them being exactly alike, and some so diverse that at first sight they would be taken for quite distinct plants. R. A. Rolfe.

To Messrs. Chesterton and Coradine, great friends and fellow collectors, we are indebted for many valuable intro- 
ductions in the orchid world, and amongst the best must be ranked the handsome Odontoglossum which bears the name 
of the latter of the two collectors. It isa New Granadan form, and was described by Prof. Reichenbach in 1872 under 
the name here given, that author considering it to be a natural hybrid between O. triumphans and O. odoratum, or a 
near ally. Its characters, however, point rather to O. Lindleyanum and O. crispum as the parents. It grows with 
these two species in the neighbourhood of Bogota, and the many forms we have flowered have all been intermediate 
between them in the colouring of their sepals and petals and other characters. It is very variable in character, and for 
this reason it is sometimes difficult to discern the parentage, but there can be little doubt that the above supposition 
is the correct one. 
The plant is compact in habit, and produces vigorous, well-developed racemes of from eight to twelve light, 
graceful flowers. The sepals and petals are tapering, of a pale primrose-yellow tint, with broad spots of rich reddish- 
brown—most effective; and the lip is of a singularly delicate hue, with a long, rich, brown blotch in the centre. It 
flowers freely, and is especially useful in the winter for associating with other Odontoglossums in the cool house. If the 
same treatment is pursued in the culture of the above as in O. luteo-purpureum, O. crispum, etc., good results will 
follow, and the cultivator will be rewarded at the proper season by a display of beautiful blossoms, which last for a 
long time in perfection. 
One of the most graceful forms of O. Coradinei is the variety known as “albicans;” its sepals and petals are 
much lighter coloured than the type, and the handsome flowers are much larger and more heavily spotted.
