A revision of Alectryon (Sapindaceae) in Malesia

The genus Alectryon occurs with some 30 species in E. Malesia, Australia, New Zealand, New Caledonia, the New Hebrides, the Solomon Islands, Fiji, Samoa, and the Sandwich Islands. Radlkofer (in Engl., Pflanzenr. 98, 1933: 983-1002) divided the genus into six sections. As a whole these sections are mostly well recognisable, but a clear demarcation between at least some of them appears impossible. Preference is given here to a division into three or four subgenera, which seems more justified. As Mr. George K. Linney, Honolulu, is working on the Pacific representatives of this genus and as Ms. S.T. Reynolds, Brisbane, recently completed a revision of the Australian species, I restricted myself in the present paper to the Malesian taxa.
