T. diguetii (subg. Tillandsia) is from the region of Manzanillo in the state of Colima, Mexico, near the central Pacific coast. It is apparently known from the type collection only. The type specimen was collected by the French Naturalist Léon Diguet and cultivated by Roland-Gosselin. The specific epithet honours the collector.
Everything about this taxon is pleasing. Plants are only 7cm tall by about 5cm diam. They don’t have the usual grey-green scales as many other species so the leaves are a light lime green in colour. This is then complimented by the reddish floral bracts followed by the lavender flowers.
