Seeds gathered by shaking seeds out over a plastic sheet, over 1 kg gathered by two people in about 2 hours. Plants very variable in appearance: a) Completely free of long slender lateral branches (i.e., unbranched) and very slender themselves, to 2.5 meters tall if growing in densest thickets with much shade and intense competition from tall herbs (Tithonia, etc.). b) Robust and branched above, with 3-7 lateral branches, if initially shaded in their lower portions (during early growth) and in competition with shorter plants. c) Branched, with 7 to 9 branches from very base if growing in among the maize plants and free of shading, here to only 1.2 meters tall (i.e. branching quite dependent on whether plants open grown or shade grown). Plants all strictly annual, without any rhizomes. No F1 seen or any evidence of hybridization. | 1336869 | PI 441933 |

Reeves & Mangelsd. | Jalisco, Mexico | NC7 |  | Not Available | 1992 | COLLECTED | 12/31/1978 | Piedra Ancha, 15 km west-southwest of Ciudad Guzman. | 19.63333333, -103.58333333 | 2150 | Within orchard and upper quebrada (ravine), gentle flat slopes, very loose soil (fluffy volcanic ash?), continually and thoroughly stirred by a large rabbit-size burrowing rodent. | Wild material | Type locality is Ciudad Guzman. Rhizomes loosely intertwined. At date of collection, primary culms with dead tassels and leaves, with mature female spikelets (with alsmot all seeds shed) most prominent, with sprouting 1-4 fresh green secondary branches (1-2 dm long) in lower half of plants not uncommon. Rhizomes locally and in great abundance sprouting slender 3-6 dm long "short shoot" culms, these with usually only one, terminal, nearly sessile, female spike hidden among the clustered terminal leaves, less frequently with 2-3 lateral spikes on stem beneath (these fertile shoots resembling plants of Panicum clandestinum). Young green "short shoots" in all stages, from mature fruit to full bloom, but no evidence of any male inflorescences (cleistogamy?). There is a more-or-less clear dichotomy between the two types of stems. Mature main stems about 1.4-1.7 meters tall. After cutting (in certain areas), the secondary female "short shoots" prominent, but the above description from an area with no recent disturbance. All short shoots coming out of the rhizomes are strictly female. The female spikes of short shoots more-or-less as fertile as those of tall shoots even without any male tassels. Informant considered plants weeds to be destroyed, and also suggested these may have been planted 30 years ago for forage, which we doubt (he was less than 30 years old). Same location as Guzman 1388. | 1087279 | Ames 21882 |
