O. crispum, but the profuse spotting and fragrance of its flowers partake more of the character of O. gloriosum; the 
spikes are invariably branched and carry many more flowers than ever O. crispum does. The forms of O. lanceans 
vary considerably as regards the size and markings of the flowers. In some the ground colour is decidedly yellow, 
whilst others have pure white sepals and petals. The colour of the markings ranges from a purplish red to a cinnamon 
or coffee brown, indeed, some forms exhibit such great differences from the typical O. lanceans that varietal names 
have been given to the most distinct. Some of these varieties show a greater resemblance to O. crispum than to 
O. gloriosum. Those resembling the latter have flowers with yellow grounds and are strongly scented, the spikes also are 
more branched. It would be difficult to find two forms exactly alike, but all are extremely pretty, it is, however, the 
sepaled forms with large flowers which generally fetch the highest prices. It can never be imported in numbers and must 
therefore always remain comparatively rare. 
The numberless forms of Odontoglossum that are presumably natural hybrids between O. crispum, O. gloriosum 
and O. odoratum, are a study in themselves, and if an orchidist were to make a point of collecting all the forms that have 
been distributed in European gardens during the last few years he would possess not only a splendid collection but one of 
immense value and interest. Such a collection would of course include all the Odontoglossa of a kindred character, such 
as O. Ruckerianum, which is supposed to be a hybrid between O. crispum and Andersonianum, O. baphicanthum between 
O. crispum and odoratum. The hybrid Odontoglossa that would fall into this class would form a very large collection, 
for not a season passes without some addition being made to it. It is a remarkable fact that though natural hybrid 
Odontoglossa are so numerous not one has yet been raised, or at least flowered, from artificial hybridisation. On the 
other hand, garden hybrids among Cypripedia are very plentiful whilst natural hybrids are exceedingly rare, if, indeed, 
any exist. 
As to the culture of O. hebraicum we must refer our readers to the treatment we have already recommended 
for O. crispum (Plate I.). It flowers during early spring and continues in perfection for several weeks. Flower spikes 
carry from ten to as many as thirty blooms on luxuriant and well grown plants. The mountains north of Bogota, near 
Pasca, is the chief locality from whence O. hebraicum and other hybrids between O. crispum and gloriosum mostly 
come, but they have reached us from other districts.
