Alaska yellow cedar (Chamaecyparis nootkatensis) , and redwood (Se- 

 quoia sempervirens) . In Martin A. and Carrie Ryerson Hall (Hall 29, 

 Plant Life) a reproduction of a fruiting branch of the medicinal cas- 

 cara sagrada {Rhamnus purshiana, see below) by Technician Frank 

 Boryca was added to the Buckthorn family exhibit. While occupied 

 with the preparation of models of various spices and food plants of 

 American origin (tropaeolum, guava, ullucus, oca, arracacha, nut- 

 meg, chayote, ginger), Artist-Preparator Grove also reproduced two 

 fruiting branches of allspice (Pimenta officinalis) that were needed to 

 augment the exhibit of the otherwise well-represented Myrtle family. 

 Curator Thieret and Artist-Preparator Grove, assisted by Preparator 

 Huebner, prepared a special exhibit on New World food plants for 

 display in Stanley Field Hall (see page 30), using various models 

 mentioned. Chief Curator Just and Artist-Preparator Grove pre- 

 pared a special exhibit on Mexican sacred mushrooms also for display 

 in Stanley Field Hall (see page 30), for which Dr. Rolf Singer, chair- 

 man of the Department of Botany at Fundacion Miguel Lillo (Tucu- 

 man, Argentina), kindly furnished herbarium specimens, living 

 cultures, and photographs and aided in the preparation of the three 

 models of Psilocybe species made by Artist-Preparator Grove.
