296 Lake Maxinkuckee, Physical and Biological Survey 



state in low shaded situations, where it clambers over brush with 

 its stiff prickles, forming dense tangles, the terror of the barefoot 

 boy. Usually known as "sawgrass." 



302. HALBERD-LEAVED TEAR-THUMB 



TRACAULON ARIFOLIUM (L.) Raf. 



Not nearly so common throughout the state as T. sagittatum, to 

 which it bears a general resemblance in habit and scratchiness. At 

 Lake Maxinkuckee a small patch was found in the low woods along 

 the creek in Overmyer's woods. 



303. BLACK BINDWEED 



TINIARIA CONVOLVULUS (L.) Webb & Moq. 



Not uncommon in open places, cultivated fields and occasionally 

 along shore. Found in blossom along the road by Green's June 20, 

 1901, and on Long Point November 23, 1904. 



FAMILY 45. AMARANTHACE^. AMARANTH FAMILY 



304. GREEN AMARANTH 



AMARANTHUS RETROFLEXUS L. 



Rather common, scattered in waste places. It prefers rich culti- 

 vated ground. Frequently found along the shore, as at Long Point 

 and the depot grounds. Exceedingly variable in size. In favor- 

 able locations the plants reach a height of four or five feet. Among 

 the pebbles of the shore at the depot grounds were perfect and fruit- 

 ing plants two inches high or less. According to Britton it some- 

 times reaches the height of over nine feet. 



305. SLENDER PIGWEED; SPLEEN AMARANTH 



AMARANTHUS HYBRIDUS L. 



An occasional weed of waste places, not nearly so common as the 

 preceding, probably of more recent introduction. Some reddish or 

 purplish plants were found in waste places near Culver. 



306. PROSTRATE AMARANTH 



AMARANTHUS BLITOIDES S. Wats. 



A member of the introduced railroad flora, found along the 

 railroad in front of the Assembly grounds in 1900, later on farther 

 south, by the icehouses, etc. A prostrate mat plant bearing a 

 superficial general resemblance to purslane.
