Olantanthera florentii is a perennial orchid that typically grows in forest understories. The stems are somewhat thin, ranging from 20 to 40 cm in height, and feature green, vertical ridges. This orchid has two glossy, oblong leaves that are opposite at the base, each measuring 5 to 12 cm in length, with wavy margins. Along the stems, small scale-like leaves are arranged alternately. The flowers are green and bloom in racemose clusters at the top of the stem, usually numbering between five and ten. The sepals and petals are approximately 5 cm long, while the lip measures about 1 cm, and the spurs, which curve downwards, are 1.5 to 2 cm long. The blooming period occurs from August to September.
