Numerous ethnobotanically important plants of the north- 

 west Amazon, especially of the Apocynaceae, collected by Dr. 

 James Zarucchi, have been added to the Economic Herbarium; 

 and an ethnobotanical collection of the useful plants of the 

 Ecuadorian Jivaro Indians made by Mr. Melvin Shemluck, and 

 extensive ethnobotanical plant collections made by Mr. E. Wade 

 Davis in South America, especially in Amazonian Peru and 

 Ecuador, help to enrich the facility. Professor Robert Bye's 

 research on the ethno-ecology of the Tarahumare Indians of 

 Mexico, and Mr. Richard Martin's studies of medicinally prom- 

 ising plants of the Peruvian Amazon, both represent unique 

 additions. More recently, collections of Hevea, Micrandra, and 

 wood samples for anatomical analyses were made by Miss Kris- 

 tine Forsgard in Brazil along the Amazon inland to the Rio 

 Negro area; and Miss Lynn Bohs' collection of Cyphomandra 

 throughout the Andes, basic to her research in that economic 



genus of fruits, have also recently been added. 



Several specialized collections of voucher herbarium collec- 

 tions have been set up in the Botanical Museum for reference use 

 by scholars — extensive collections devoted to a single genus or 

 species which are or will be valuable to future monographic or 

 analytic studies. Among these are Professor Paul Manglesdorfs 

 extensive maize herbarium, Dr. Walter Hodge's collection of 

 Cinchona, mainly from Peru, and several thousand specimens 

 of Hevea and its relatives made by Professor Schultes in the 

 Amazon Valley. Also available is a Cannabis collection of sev- 

 eral hundred specimens from many different areas of North 

 America, Europe and Asia, many collected from the National 

 Institute of Health-sponsored cannabis plantation in Missis- 

 sippi. The collection is comprised of material introduced and 

 planted from more than 300 localities around the world; their 

 classification basic to a modern interpretation of the genus 



Cannabis. 



There are five other herbaria at Harvard University, and every 

 attempt is made to avoid duplication in the Economic Herbar- 

 ium of material available in other institutions. The specimens at 

 the Botanical Museum are, however, equally available to both
