Morphological Description

Diagnosis: Species of Pelexia are very similar to those of Sarcoglottis, bearing mostly green flowers typically with pubescent flowers and inflorescences. In Pelexia a short stubby external spur is visible in contrast to the spur of Sarcoglottis which is wholly internal. The only somewhat similar flower in the flora is Sacoila which has reddish smooth flowers and typically flowers without leaves present.
