The Oncidium Section Cimicifera
Plants of this Section are distinguished by the very fleshy nature of all segments (sepals, petals, and lip). The flowers are always small to minute in size, inconspicuous on the plant. The column also lacks adornments to the side of the stigma.2
20 species are listed 2, these being ballii, brachystachys, cimiciferum, cocciferum, diodon, exasperatum, macropus, meirax, mentigerum, murinum, porrigens, rotundatum, rusbyi, rusticum, saltabundum, saxicola, tricostatum, trulla, turpe, and umbonatum.
Moir8 notes there are two divisions in this Section - some with very plain flowers and those that have extra frills to the base of the triangular shaped, very convex lip. He believes these later ones have been placed incorrectly in the Rostrata Section, which they do not resemble at all except that they have somewhat similar bases to the lip, while the true Rostrata species have lower lobes in addition. Those able to secure and grow these plants could have an interesting time trying to sort out this Section in view of Moir's comments.
These plants are in the main natives of Ecuador, Colombia and Venezuela, 6 requiring cool moist airy conditions, although a number will appreciate come winter heat. They will also appreciate some shade from direct sun, although still require bright conditions.
Because of the small flower size these plants would not appear to be of interest in a collection, other than for those interested in the 'botanical' type of orchids.
Remember, growing orchids is all
about enjoying your plants
Good luck and good growing.
