COMPOSITE FAMILY 



GALINSOGA 



Galinsoga parv'iftora Cav. 



This weed is becoming quite prevalent throughout Illinois, 

 overrunning gardens everywhere. It is a native of tropical 

 America which frequents dooryards and waste places nearly 

 throughout the United 

 States. Galinsoga is the 

 only name it has, and that 

 comes from Dr. Mariano 

 Martinez de Galinsoga, a 

 Spanish botanist. 



An annual branching 

 herb, Galinsoga grows 1-3 

 feet high and blooms from 

 June to November. The 

 lower of the thin and 3- 

 nerved, opposite leaves 

 are usually toothed and 

 have slender petioles, 

 whereas the upper are 

 sometimes nearly entire 

 and are short petioled or 

 sessile. 



Numerous heads, each 

 with 4 or 5 white ray flow- 

 ers and many yellow disk 

 flowers, are borne on slen- 

 der peduncles. The involucre is broadly bell shaped and its 

 smooth ovate bracts are arranged in 2 series, the outer slightly 

 shorter. The somewhat cone-shaped receptacle has thin chaff 

 among the disk flowers, which are perfect and have ^-toothed 

 corollas. The pappus consists of 4-16 oblong, bristle-tipped or 

 cut-fringed scales. The pistillate rays are short and with a few- 

 bristled pappus or none. The akenes are somewhat angled or 

 flattened and covered with fine hairs. 



The morning glories ripple o'er the hedge 



And tieck its greenness with their tinted foam; 



Sweet wildling things, up to the garden's edge 



They love to wander from their meadow home, 



To take what little pleasure here they may 



Ere all their silken trumpets close liefore the warm midday.
