The Economic Herbarium is catalogued under the Dalla 

 Torre and Harms' genus number. It is closely integrated with an 

 extensive collection of economic and ethnobotanical plant parts, 

 including seeds, fruits, flowers, roots, woods, barks, oils, resins, 

 rubbers and other vegetal products. This teaching collection of 

 useful plant products numbers well over 14,000 entries and has

300 related charts and graphics and a clipping file assembled 

 over the past fifty years. All of these facilities are reinforced for 

 teaching and research by the topically indexed interdisciplinary 

 Economic Library of Oakes Ames with well over 35,000 titles. 



A recent addition from the New York Botanical Garden is the 

 collection of economic plants of Dr. Henry Rusby, dating from 

 the early 1900's. Representing only a portion of Rusby's col- 

 lected material, the 4000 specimens, stored in antique apothe- 

 cary jars, is a unique part of a massive accumulation of 

 medicinal and general economic flora from Arizona, New Mex- 

 ico, Colombia, Brazil and the Lower Orinoco area. A prelimi- 

 nary examination of this outstanding collection by Miss Susan 

 Rossi has already produced a long-lost type specimen of Ery- 



throxylon truxillense and promises to yield other critical speci- 

 mens.
