Information
Stigma-bases and upper part of lid of fruit more or less swollen, so that the fruit has a more or less inflated beak. Inner perianth segments of female flowers commonly (but not always!) acute. Longer bracteoles of female flowers mostly about twice as long as the perianth.
Habitat
In the Flora Zambesiaca region a weed of cultivated and disturbed ground along roadsides, in trampled grassland etc.
Range
This subspecies occurs throughout the tropical and subtropical regions of the world as a wild or spontaneous plant, also occurring as a casual in temperate regions, e.g. as a common wool adventive in Europe; it is of American origin

Notes
Forms of this subspecies with red inflorescences can be called var. erythrostachys Moq., the colour, however, fades and herbarium material eventually becomes green.An abnormal form occurs with the lower partial inflorescences globular and their final branches somewhat elongated and pectinate. This is Suessenguth's “var. verticillatus”. It has been received as grown in Harare from seed found as a contaminant of “Red Manna” (Setaria cf. italica) seed (Seed Services VS/110 & VS/118). An even more extreme abnormality of this type was collected in an old maize field in the Chilanga District of Zambia by Mrs. C I Sandwith (No. 143, K) in 1924. The extreme variability in size of this plant is shown by the note on the herbarium sheet (Best 96 from Lusaka, K) that it was “7.5 cm. to 2.1 m. or more in height” at this one locality.
