Berlandiera texana DC. 



Similar to Berlandiera dealbata but stems are not as woolly, 

 and leaves are broadly lanceolate. Eay flowers f al Isoon. In tKe 

 limestone hills of the Edwards Plateau. The genus Berlandiera 

 is named for Jean Luis Berlandier, a Belgian, who was for some 

 years in the service of the Mexican government. He was probably 

 the earliest botanist to visit San Antonio, where he collected 

 about 1827. 



Lindheimera temna Gray & Engelm. Texas Star. 



Hairy plants with coarse, leafy stems and yellow, composite, 

 4 or 5-rayed flowers, over 1 inch across. Upper leaves simple, 

 opposite. Blades entire or wavy, sometimes toothed. Eays 4 or 

 5, about % inch long, notched at the tip and curling back in the 

 hot sun. Achenes broad, with 2 divergent teeth at the apex. 

 Upper stems often covered with hairs that are discolored (red) 

 at the base. Widespread. March to June. Plants blossom when 

 not over 2 inches high and continue to blossom until they get 

 about 2 feet tall. One of our most common early composites. 

 Named for Ferdinand Lindheimer, an early Texas botanist and 

 resident of New Braunfels. 



Engelmannia pinnatifida Torr. & Gray. Engelmannia. 



Stout-stemmed, coarse-haired, leafy plants with yellow, com- 

 posite, 8-petalled flowers, 1 to 2 inches across. Upper leaves 

 simple, opposite, sessile, usually deeply lobed along the margin. 

 Eays curl back in the hot sun. Achenes flat, broadened upward, 

 one rib on each face. March to June. Common, usually growing 

 in patches along the road and in pastures. Often mistaken for 

 Lindheimera but easily distinguished by the larger number of 

 ray flowers and the deeper lobed leaves. 



PartJienium Tiysterophorus L. Eagweed. 



Branched plants, 1 to 4 feet high, with ridged, fibrous stems,
