Notes:
Also called road weed, mat weed, knot grass, pig weed, and bog weed. It is common in cultivated land all over the country. It is an annual, with stems up to 2ft. [feet] in length trailing over the ground. It never lifts its stems even an inch in height. The stems have swollen nodes ('knot grass') and are very tough ('wire weed'). The leaves are simple, almost stalkless, about an inch in length and like a lance head in shape.
Specimen notes
Herbarium history:
This specimen is part of a collection given to the Allan Herbarium by Laurence Smith (Amberly office, Environment Canterbury). This was given to L. Smith in the early 1990's by someone in Port Robinson, Cheviot.
The collection is believed to have been collected in 1948, based on several specimens with fully written dates in the collection. We believe that JRK is a student of Canterbury Agriculture College (C.A.C), which is now known as Lincoln University.
