Extensions of ranges were noted for four species, but no new species were described. Two new collec-tions of poorly collected and poorly understood Anomospermum matogros sense were of particular interest. The chemical work on neotropical Triclisieae and Anomosper -meae by Prof. Michael P. Cava and his associates continues, as may be seen from the bibliography. Abuta splendida , Sciadotenia toxifera and Abuta grisebachii were studied, and four new ben-zylisoquinoline alkaloids (krukovine, sciadenine, grisabine, and grisabutine) were isolated and characterized. Of the 16 known New World genera of Menispermaceae, chromo-somes were studied of only four genera ( Calycocarpum , Menispermum , Cocculus , and Cissampelos ) . Dr. William L. Theobald, director of Pacific Tropical Botanical Garden in Hawaii, is now receiving seeds, largely from the collectors of MO and NY. It is inter-esting that the first two batches of seeds were sent by Dr. J. -J. de Granville from French Guiana. They were of the recently described remarkable Elephantomene eburnea and Anomospermum sp.; seeds of these germinated four to five months after planting.
