Hort. and Z. minima Hort.). A very dwarf, slender 

 form with green leaves, sometimes cultivated for 

 ornament. 



10. ZEA mays L., var. CURAGUA (Molina) Alefeld ; (Z. 



Curagua Molina). A robust green-leaved form, grown 

 for ornament. Considered by Sturtevant (2) to belong

22S. Pod Maize {Zea Mays var. tunicata St. Hil.) ; (Fig. 5 1). 

 — In this breed each grain is enclosed in a pod or husk formed 

 by the enlarged glumes ; the whole ear also has its usual coat- 

 ing of husks formed by the leaf-sheaths. 



Vernacular names: Pod corn, cow corn, stock corn, forage 

 corn, husk corn, primitive corn, California corn, Egyptian corn, 

 Rocky Mountain corn, Oregon corn (United States) ; pinsin- 

 gallo (Buenos Aires) ; manigette (Ethiopia) ; balg-maiz 

 (Germany), 



The grain is small and very flinty, often with a sharp beak, 

 and is said to be particularly resistant to weevils. Dr. Sturte- 

 vant (2) notes that once his whole collection of maize breeds 

 (an exceptionally fine one) was destroyed by weevils, except 

 the pod maize. The plant is excessively leafy, and has a 

 great tendency to sucker. The tassels are unusually heavy 

 and are inclined to be grain-bearing. 



Caspar Bauhin in 1623 referred to the occurrence of pod 

 maize in Ethiopia, under the name of manigette. Sturtevant 

 was inclined to look upon it as the aboriginal form of maize, 

 but admitted that it may be an abnormal and proliferous state 

 of the flint variety. Darwin considered that the aboriginal
