Brenan, J.P.M.: The value of Floras to underdeveloped countries (Impact 13, 1963, 122-246). An excellent justification of the composition of tropical Floras with special stress on their usefulness for mankind. This essay should be in the hands of all administrators in these countries, for the matter and its presentation is easily understandable to educated non-botanists. It appears to me that the use for scientific botany, taxonomy and plant geography should have had more attention; in these more pure branches of botany, underdeveloped countries should also have their share. -- v.
