TuiIs has the genuine habit of Odontoglossum crispum, Lindl. and the infl of Od 1 odoratum, Lindl, but is usually much 
st named. It usually has longer leaves and a richer infl than Od i crispum, Lindl. The sepals and petals generally 
are bright yellow, with dark brownish purple spots or lines (b. lineoligerum). The lip has a channelled nail and is nearly hastate at the base, running in a 
lanceoacuminate lamina. This is also yellow and dotted, having usually a large spot on disc. The callus is the chief point. It never consists simply of the 
two lamella, running parallel, showing a tooth at both ends. I have always found it aberrant, very often too with small lateral teeth. The column is scarcely 
ever found to be exactly the same shape as that of Odontoglossum odoratum. There are adventitious teeth on the border of the fovea under the chief tooth, 
and when that one happens to be developed alone it is abnormal in its breadth.

IT had this from Mr. W. Bull. It has since appeared at various instances, sometimes showing a wonderful design, as in specimens I had from Messrs. 
H.. Low and F, Sander. The plant we represent is remarkable for its very large flowers.

A Lone time elapsed before we acquired a positive knowledge of these curious Odontoglossa. We had to classify what we 
saw, to put down the characters. These plants have innumerable disguises as to colours, which often appear more 
constant than the characters taken from the lip and column. 
Owners of nurseries always liked distinct names for distinct looking plants, and the amateur himself was perhaps 
never so particular as at the present day in expecting to have just the thing as he likes it. If somebody orders an 
Odontoglossum Ruckerianum he may not be satisfied with an Odontoglossum hebraicum. I feel persuaded, therefore, 
that the system of naming the different varieties is really necessary. I have often declared that I do not regard these 
plants as species, and my proposition to put a cross (+) before the name fully proves this. 
Instances have occurred, however, which prove to us that, regular as those marks are, Nature does not admit them 
without exceptions Flowers have been seen of different colours on the same general peduncle, and the typical colours of 
white, yellow, or mauve are not always adhered to as invariable ground colours, but they appear mixed. There are 
yellow flowers with white discs, and yellow or white ones washed with mauve. 
As it is, we may now classify the Odontoglossa + Andersonianum, + Jenningsianum, + baphicanthum, + 
hebraicum, + Brassia, + deltoglossum, + Leeanum, + Ruckerianum, as so many secondary types of one primary type, 
Odontoglossum lanceans. I may avail myself of another opportunity to give full quotations, adding several synonyms. 
At the present I can only give a sketch of the whole so far as I know it. H. G. Rehb. f. 
Ever since Mr. Bull flowered the first plant of this Odontoglossum it has been regarded as one of the 
choicest and loveliest in the genus. It is considered to be a natural hybrid between O. crispum and O. gloriosum, 
the essential characters of these two species being blended in its growth and flowers. In growth it most resembles
