The posterior lobes of the petals about 1.5 times longer than the anterior, [vs much shorter in H novemfida and much longer in H brownelliana], and the lobes of the lip more or less the same length [vs the laterl lobes much longer in H novemfida and H brownelliana]. The leaves are much broader. H novemfida is found at elevations around 2000 meters, the new specis occurs close to sea level.
