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

comes from Dr. Mariano Yah )

Martinez de Galinsoga, a SW 
Spanish botanist. i eee 
An annual branching IN y) 
herb, Galinsoga grows 1-3 
U, 
feet high and blooms from Sf, 
June to November. The 
lower of the thin and 3- Vas 
nerved, opposite leaves meee 
are Bt Soothes and = 
have slender petioles, a 
whereas the upper are \ 
sometimes nearly entire \\ 
and are short petioled or \ 
sessile. | 
Numerous heads, each h 
with 4 or 5 white ray flow- i 
ers and many yellow disk Gv 
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 5-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 fleck 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 before the warm midday.
