Wants Oxalis specimen named; is fascinated by cotyledonary movements of the genus.
Before JDH discusses flora of Canary Islands CD suggests he read F. B. White’s paper [see 11707], which explains stocking of Atlantic island fauna as due to changed currents during [last, or Miocene] northern glacial period.
Frank asked to summarise work with CD for use in JDH’s Royal Society address.
Work with A. Gray shows Colorado plants closer to Altai than to E. or W. America.
Work with J. Ball shows Moroccan plants very distinct from nearby Canaries.

Botanical evidence is against F. B. White’s origin of St Helena fauna. JDH holds flora is S. African. Since plants must arrive before insects, if fauna is Palearctic then flora survived glacial period. Flora not Miocene since old and relic orders are absent. Suggests S. African west coastal mountains as insects’ origin.
