The Oncidium Section BARBATA
The 13 species listed 2 in this Section have conspicuous leaf bearing pseudobulbs. The flowers have spreading sepals and petals, the lateral sepals variably joined, and are larger than the lip. The lip has in most cases sharp pointed teeth on the margins pointing outwards, or a fringed isthmus. The disc has an uneven number of serial or scattered tubercules. The rostellum is short.2
Both One. eurycline and longipes are indicated as being pretty dwarf growing species producing short racemes of flowers in great abundance.(7) This is another Section containing small attractive plants suitable for those with restricted growing space.
These species are indicated to be requiring intermediate conditions. For Onc. barbatum, Williams 7 indicates it succeeds best on a block, but that it must have good attention to the supply of water at its roots. This species is from the monsoonal foothill mountain habitat, and this informaiton can be usefully referred to for broad cultural guidelines. Its requirements for a seasonal dry/moist enfironment should be noted.
Remember, growing orchids is all
about enjoying your plants
Good luck and good growing.
