Hitchcock was in Ecuador last year he secured seeds of a promising forage grass from the Hacienda La Teresita, near Bucay. His notes on this plant, which was called Paspalum scoparium at that time, are given under S.P.I. 58966. The seeds failed to grow, and at Doctor Hitchcock's request I have secured from La Teresita, through Mr. Cleveland, the owner of the hacienda, live plants of this grass, which will be tested in Florida and other subtropical regions.

| 60 | PI 58966 | | Axonopus scoparius (Humb. & Bonpl. ex Flüggé) Kuhlm. | Guayas, Ecuador | | | Historic | 1924 | COLLECTED | | | | | | | This South American grass is used at low altitudes for forage, being cut green and fed as is done with guinea grass. I saw it first on the estate of J.A. Cleveland, of Guayaquil, in the rain belt at the foot of the mountains near Bucay. The grass is set out from plants obtained by division of the roots. It is called there "gramalote." I suspect this name is the same as gamalote, which is used for a different species in some other countries. The grass appears to be looked upon with favor, as it is large and succulent and produces abundant forage. It is preferred to guinea grass, which grows under about the same conditions. I found the same grass again in the Perene Valley of central Peru at an altitude of about 2,000 feet. There it is called maicillo and is used in competition with guinea grass. It appeared again in the Yungas region of Bolivia. It is there called cachi. In the intermediate altitude from 5,000 to 8,000 feet it was the only forage obtained for our mules while traveling. Throughout the region the grass is native and has been transferred to cultivation. (Hitchcock.) | 1499928 | PI 58966 |
