Sandbur - Cenchrus longispinus
THIS PAGE IS UNDER CONSTRUCTION.
Longspine sandbur is an annual grass. The leaf blades are smooth, flat
or rolled, 4-14 cm long, 3-7 mm wide. Leaf sheaths are usually glabrous
but sometimes are sparsely ciliate. The burs are borne in short spikes
along a zigzag rachis and fall off at a touch when ripe. The spines of
the burs are very sharp and each spine is microscopically backwardly barbed.
Longspine sandbur has culms 2-6 dm tall, usually spreading and making
mats. It grows in cultivated fields, pastures, roadsides, and waste places.
It is generally more common on sandy land than on heavier soils.
The spiny burs can inflict painful and dangerous flesh wounds to man
and animals. They also can become lodged in fur or wool.
