Narrative

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.
