Original publication in ICONES ORCHIDACEARUM PERUVIARUM," fourth installment.
A newly published species, based on collections made in Perú; named in honor of Dr. Alex Hirtz, of Quito, Ecuador.
This species is similar to Sobralia fimbriata, which also has fimbriate petals. However, S. hirta has more finely divided petal margins, smaller petals, and is only seen in Peru.
Erica Moron de Abad ( firstname.lastname@example.org ) provided the photo at left. She found the plants in Perú at 2100 m elevation, growing 1.6 m tall, usually bearing two fragrant flowers, lasting only a day. However, her plants bloomed for 4 weeks.
