ODONTOGLOSSUM SCHRODERIANUM. 
[PLaTE 382 ] 
Native of Ocana, U.S. of Colombia. 
Epiphytal. Pseudobulbs oblong-ovate, somewhat compressed, becoming wrinkled 
with age, deep green and leafy at the base, the radical leaves broadly oblong: -acute, 
the apical ones more lancoolate: channelled in front, keeled behind, and deep green. 
Scape erect, many-flowered, the blooms yielding a delightful fragrance resembling 
Vanilla. Dorsal sepal and the petals about equal, erect, lateral sepa s longer and 
spreading, all oblong-acute, wavy, white, with numerous blotches .of purplish mauve ; 
ip adnate to the base of the column, pandurate, the basal portion broad, the 
anterior part obcordate, flat and apiculate, white in front, the dise bearing two 
purplish mauve blotches, the calli yellow, dotted with red, and on the much- 
developed callus at either side in front of the column is a plate of radiating 
spines. Column white, passing into yellowish towards the base, the wings white 
and dentate, sparingly dotted with purplish mauve. It is a supposed natural 
hybrid between Odontoglossum tripudians and O. Pescatorei.

The genus Odontoglossum has now become very numerous, and especially so in 
kinds which are supposed to be natural hybrids; indeed, these forms appear to be 
endless, many of them being exceptionally beautiful. New importations are always 
anxiously searched with a view of detecting them, and in nearly every instance some 
very valuable form is met with. At present we have done very little in cross- 
breeding this genus, but as these plants grow freely from seed, even at home under 
cultivation, there is little doubt but those amongst us who are devoting their energies 
to this work may be rewarded with some startling novelties. It would appear that 
Odontoglossums intercross in a remarkable manner in a state of nature, then how much 
the more likely are growers at home to be successful, when the number of fine kinds 
growing together in close proximity is taken into consideration? But yet, anyone 
interested in these plants, and living in their native country, should endeavour to 
collect as many different species together in one spot as possible; these would soon 
become established, and when in flower cross-breeding should be effected; in which 
operation insects would also take an active part. Here the seeds would distribute 
themselves and quickly vegetate, for being in a natural state they should grow faster 
and flower more quickly than with us under our artificial conditions, whilst nothing 
can be effected without patience and perseverance, we have made this suggestion with
