|Iris × corygei Lynch, Book of the Iris: 146 (1904). Lynch provided the following description: </brI. Corygei. This plant was received at Kew some years ago from Dr Lange, but I have no further information of its origin. It is remarkable among all its allies on account of its green leaves. They are about 20 in. long and if in. broad, very falcate and so weak that many of a clump bend over. The surface is very uneven on account of prominent ribs. Mr Baker considers it a close ally of I. neglecta, and says that it has orbicular spathe-valves an inch long ; falls pale lilac towards the tip, veined on the haft with drab yellow on a white ground. As I have no flowers at all this season, it cannot be described as free flowering.
|Dykes in The Genus Iris, 1913. I am indebted for plants of this Iris to Mr Lynch, of the Cambridge Botanic Garden. It is, in my experience, neither robust nor free-flowering. However, the warm weather in the summer of 19II and in the spring of 1912 caused the plants to throw up several flower stems, which showed that this Iris is almost certainly of hybrid origin and that one of its ancestors was I. variegata.The leaves are falcate, strongly ribbed and not very glaucous. The spathe valves are short, somewhat inflated, green at the base and scarious in the upper third. The short ovary is six-grooved and the tube about 1 in. long.The falls extend almost horizontally,-a characteristic feature of I. variegata-and are of a pale blue lilac colour on the blade and veined with yellow-brown on the greenish-white haft. The beard is yellow. The almost orbicular standards are of a still paler shade of light lilac than the falls and they show distinct traces of a suffusion of yellow.
