The similarity in uses of Xylopia amazonica and X. 
Benthamii— to induce sleep and as a tranquilizer, respectively — 
Suggests the advisability of chemical and pharmacological 
research. 
M YRISTICACEAE 
Osteophloem platyspermum (Poepp.) Warburg in Nova Acta 
Acad. C. L. C. G. Nat. Cur. 68 (1897) 162. 
BRAZIL: Estado do Amazonas, basin of Rio Negro, Rio Uneiuxi Maku Indian

diameter. Flowers green. Sap drunk by Maku as cure for coughs and colds.

The Maku drink the sap as a “cure for coughs and colds.” 
Labourers in the Reserva Ducke near Manaos burn the leaves 
and inhale the smoke to relieve asthmatic conditions. 
Chemical studies of Osteophloem apparently have not been 
effected. 
CHRYSOBALANACEAE

Wien 4 (1889) 54.

Diameter 15 inches, height 75 feet.” March 8, 1951. R. E. Schultes et I. Cabrera 
13276. 
The bark of this tree is burned, and the ashes are mixed with 
clay for making pots. The tree is known locally in Spanish as 
cabio. Its Indian names are: Kabuyari—ka ’-ve; Kuripako — 
ka ‘-be; Taiwano —hna-mwa; Puinave—wan-choo ”.
