SANTIAGO-ZAMORA ("Oriente"): Near Mendez, 1750-2500 ft, E-947. "Trigo Tropical." Propagated by the padres of the Sileciano mission at Mendez, and said to have been brought in (five seeds) from their mission in Colombia two years ago. Leaves somewhat narrower than the wild sort, the most notable and obvious difference being the ribbing on the indurated sheath (fruit covering) and more yellow color at maturity. Physically, this sheath is much thinner than in the wild sort, so that it can be easily cracked between the fingers. This permits it to be milled more easily than the wild sort. The flour is said to be a little heavy and needs to be mixed with wheat flour before it can be used for bread. It is said to be of excellent flavor and to have possibilities as a tropical substitute for barley and other such grains. Horticulturally, it is a better plant than the wild one, for it seems to be more fruitful and also to have the inflorescences lifted above the leaves a little more. At present, the crop is curtailed by the invasion of rodents just at harvest time as grains mature. The padres have found it necessary to eradicate the wild material since the two hybridize. Same locality: "wild type," propagated for rosary beads, E-948.
