Abutilon theophrasti (commonly known as velvetleaf) is a summer-emerging, annual, broad-leaf weed native to Asia. The species can be found mainly in the Central Valley (and mostly in the Sacramento Valley) in agronomic crop systems, along roadsides, in orchards and vineyards, and in other disturbed areas.
Cotyledons (approximately 1/2 inch (12 mm) long and wide) are rounded to heart-shaped in appearance. The first true leaves are heart-shaped with with shallow and rounded-toothed margins. Velvetleaf cotyledons, leaves and petioles are covered with fine, soft hairs (hence the name 'velvetleaf').

Growers (mainly pistachios) and crop consultants in the southern and western parts of the San Joaquin Valley have recently reported the spread of alkaliweed from low-lying saline or alkaline soils (including seasonal wetlands and floodplains) into irrigation ditches, orchards, and some agricultural fields (Figure 1).
Now, some of you may be asking 'What is alkaliweed?'
Alkaliweed (Cressa truxillensis) is a native, perennial plant in the morningglory family (Convolvulaceae), the same family of field bindweed (Convolvulus arvensis) and dodder (Cuscuta spp.). The species has a prostrate to ascending growth habit, rarely exceeding a foot in height. The species produces grey-green,...
