My dear Dyer

I sh^d. be greatly obliged if you could tell me the name of genus & nearest species of enclosed leaf. It was given to my gardener by another gardener as a Caladium.² It has never flowered with me: all the leaves are like the enclosed, but somewhat larger & they rise from a great conical stock or corm or tuber.— I enclose addressed card & you need only write name (if leaf can be recognised) at back.—

I want to know name, because the leaf moves so much at night from horizontal to 69° below horizon, that it deserves to be said to sleep, & monocot. sleepers are rare.—³

yours very sincerely | Ch. Darwin
