Has sent two Impatiens flowers; curious to know what Darwin makes of the floral whorls and their vascular bundles. Cassia is another genus that has different coloured anthers in same flower. Continues to work on Welwitschia. Feels as Darwin does about his work, which after a time seems flat and stale. He could never have done what Darwin did in his Orchids. Darwin's facts about Verbascum have horrible bearing on Hooker's practice of lumping species together.
