Epiphytic, sometimes rupiculous herbs, 15.0−56.0 cm tall. Pseudobulbs conical, 5.0−11.0 × 1.0− 1.5 cm. Leaves 2−3, oblanceolate, 12.0−45.0 × 1.0− 2.5 cm, apex obtuse. Inflorescence a densely 7−25-flowered, compound raceme; peduncle 26.0−50.0 cm long; rachis 20.0−40.0 cm long. Floral pedicel 2.4−2.9 × 0.3−0.4 cm, warty; sepals brownish green, dorsal lanceolate, 2.0−2.5 × 0.7 cm, laterals lanceolate, 1.9−2.5 × 0.6−0.8 cm, pendent, margin entire, apex acute; petals brownish green, spatulate, 1.8−2.6 × 0.8−2.0 cm, pendent, margin entire, apex acute; lip with claw 0.15−0.2 × 0.3−0.4 cm, lateral lobes free in relation to the oval midlobe, 0.7−1.2 × 0.5−0.6 cm, yellowish, at a ˂45° angle with the midlobe (in the flattened lip), sometimes overlapping it, margin entire, apex obtuse, midlobe deltoid, 0.9−1.2 × 1.2−1.8 cm, white with few pinkish traces, flat, margin gently undulate, apex emarginate, callus cymbiform, acute; column clavate, 1.0−1.2 × 0.4−0.5 cm, clinandrium apex tridentate, lateral teeth triangular, apex acute, arms of the column quadrate, 0.15−0.20 × 0.20 cm, apex obtuse; stigma rounded, with basal hooks; anther one, yellow.
Distribution and habitat:— Endemic to cerrado in the north, central west and southeast ( Fig. 16 View FIGURE 16 ).
Phenology:— Flowering May–February.
Etymology:— From Latinized Greek “osmos”, perfume, and “anthus”, flower, referring to the fragrant flowers.
Taxonomic notes:— Encyclia osmantha has been commonly confused in herbaria with E. advena and E. alboxanthina . However, E. osmantha differs from these in its deltoid lip midlobe, which is is reniform and rounded in E. advena and E. alboxanthina , respectively. In addition, when flattened, the lateral lip lobes in E. osmantha form a <45° angle with the midlobe, whereas in the other two species this angle is about 90°. Some other nomenclatural questions involving E. osmantha were included in the notes for E. advena .
Although the type of E. cardimii is incomplete, with only a portion of the inflorescence and two flowers, we conclude that E. cardimii corresponds to a variant of E. osmantha , as previously explained in the notes on E. oncidioides . Our only concern in making this decision is the statement that is has a rupicolous habit, whereas E. osmantha is often reported as an epiphyte. There is, however, at least one collection of E. osmantha (Forster & Mazine 818, ESA 86119), also from Minas Gerais, that was collected growing on rocks, so we know that occasionally E. osmantha can be rupicolous.
