Acineta (immovable, referring to the jointless lip). Orchidaceae. Epiphytic hothouse orchids.
Pseudobulbs conic or ovate, with the large plicate-veined lvs. articulated to the summit: fls. fleshy, borne in pendulous racemes on lateral leafless scapes; sepals broad, equal, finally somewhat spreading; petals similar to the sepals but smaller; lip fleshy, continuous with the base of the column, the middle lobe continuous or articulated, entire or 3-lobed; pollinia 2.—About 10 species, distributed from Mex. to northern S. Amer.
These plants require a warm house and plenty of moisture during the growing season, with a decided rest, to make them flower. They need to be cultivated in wooden baskets and suspended from the roof of the house, as the flower-spikes are always produced from the base of the bulbs and there should be no hindrance in the way of crocks to prevent their egress. The rooting material may be peat fiber only, and not a great quantity under the plants, but plenty around them. With basket culture of orchids, it is very necessary, once a week in the growing season, to take the plants down and give a soaking by immersion, in addition to the ordinary spraying overhead from day to day; in this way alone can one be sure of the proper growing conditions. In winter, much less water is required. Propagation is by division of the plants in spring. (Orpet.)
