April ; thicket forming by means of suckers ; shrubby northward ; often per- 
sistent and dithcult to eradicate from fields; thickets often vigorous and 
dense; a lepidoteroiis larva injures the flowers throughout a good portion of 
its range, but when not attacked, fruit is abundantly produced; otherwise gen- 
erally free from in.sect enemies ; two forms are known, one with white, insipid 
fruit ; the other with a yellow pulp, but these are not recognized botanically ; 
propagation is by seed sown as soon as ripe; suckers are generally ditflcidt to 
transplant : about 1.2()0 seeds per pound, germination about HO percent, about 
2.10 usable i)lants per jwund of seed.

to livestock.
