Note 4 — Chapter IV

I owe these names to the kindness of the authorities at the Royal Gardens at Kew, who have been good enough to look through fifty-four dried specimens which I collected and preserved as well as I could while travelling through Mashonaland and Basutoland. Eleven of these fifty-four were pronounced to be species new to science, a fact which shows how much remains to be done in the way of botanical exploration.
