Typescript and manuscript drafts of sections, with notes. Most of the material appears to relate to the above article. Many of the section and sub-section titles correspond to those in the published version, though it is possible that there are pages relating to other Oenothera papers, including the one descibed in C.273-C.275. The draft is in a disarranged state, with fragmented pagination. It has been listed in the order in which it was found. Manuscript pages are in Darlington's hand unless otherwise stated.
