314 Prof. Don's Descriptions of the Indian Species o/^Iris. 



hinc convexa, inde biangulata, raphe pallidiori elevata aiicta, apice ap- 

 pendice obtusa fungosa carunculata, basi hilo parvo instructa : testa 

 coriacea, rugosa, brunnea, epidermide laxa, pallid^ fusca: albumen co- 

 piosiiin, cartilagineo-carnosuin, album. Embryo teres, medio paululiim 

 constrictus, clavatus, albus, extremitate radiculari (cauliculari) crassiori. 



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 Sisyrinchium, 

 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.
