The Herbarium contains material of value to monographers 

 and general taxonomists, including a few types, numerous 

 duplicate types, and drawings of types. There are extensive 

 unique or rare collections which may be of critical or historical 

 importance to students of taxonomy and floristics. Iter Warburg- 

 ianum, the Faurie, the Kunstler, the Species Blacoanae and 

 other rare collections are among those of special interest. A 

 complete herbarium of Maiden's Useful Plants of Australia, 

 only a few sets of which are known, is preserved in the Economic 

 Herbarium. Ruiz and Pavon's collection of Cinchona barks, a 

 gift from the British Museum (Natural History), and other spe- 

 cial generic collections have very significant historical value to 

 students of economic botanv. 



The Herbarium was initially very rich in Asiatic material. 

 During the past forty years, however, research programs and 

 field work in tropical America have added ample collections 

 from this new world region. The extensive collections of Schultes 

 in Southern Mexico and South America, especially in the 

 Amazon; and the ethnobotanical specimens basic to the studies 

 among the Kamsa and Kofan Indians of South America by Dr. 

 Melvin Bristol and Dr. Homer Pinkley respectively, have en- 

 riched the Economic Herbarium. Dr. Tommie Lockwood's col- 

 lection of Brugmansia primarily from the Andes, and Dr. 

 Timothy Plowman's extensive collections of Erythroxylon and 

 Brunfelsia as well as many other general ethnobotanical species 

 from Colombia and Peru have been added as valuable resource 

 material to the Herbarium. The Theobroma specimens basic to 

 the thesis of Dr. Wertit Soegang are available, and the material 

 on oil palms, especially of the Jessenia-Oenocarpus complex, by 

 Dr. Michael Balick, are included as well. Representative mate- 

 rial of Dr. Doel Soejarto's extensive collection of South Amer- 

 ica Saurauia have been deposited in the Economic Herbarium; 

 and among additional noteworthy collections from other areas 

 are Vestal's ethnobotanical specimens from the Navajo Indians; 

 Schultes' useful plants of the Kiowa of Oklahoma; and Miss 

 Marjorie Whiting's plants of the Kung Bushmen of Botswana, 

 Africa.
