This species departs from the rest of the genus in so many points, that it 
may safely be ranked with those which, like Iris tuberosa and Stsyrinchium, 
appear to constitute the types of so many distinct sections. The rhizoma is 
exactly that of Hemerocallis, being furnished with thickened fusiform fleshy 
fibres, and the leaves are likewise remarkable for the diversity of colour of 
both surfaces, the inner one being of a bright green, and the outer one glau- 
cous. The sepals are uniform, bilobed, and recurved, the outer three being 
furnished along their centre with a peculiar membranous crest or fold. The 
stigmas are remarkably broad and connivent. The seeds are furnished at 
their apex with a thick, compressed, fungous appendage, resulting from an 
unusual development of the testa at that point. 
This species has been introduced to our collections by Dr. Wallich, and is 
remarkable for the elegance of its habit and the beauty of its flowers. 
I have referred under this species Thunberg’s Iris orientalis ; but an exami- 
nation of authentic specimens is necessary to solve our doubts on this point.
