Health better, but paralysis lingers.
Considers some flowers especially adapted for self-fertilisation, and believes all flowers are self-fertilising under some conditions. Gives examples of plants in which he believes all flowers are cleistogamous. Believes self-fertilisation is the primordial condition of flowering plants.
Floral structure. The order of the development of the whorls and its relationship to a protandrous or protogynous condition in flowers.
