the yellow flowers the plant is quite ornamental. Bello gives the names ‘‘ boton

Leonurus sibiricus. AGRIPALMS. 
A herbaceous annual weed of the mint family. (Stahl, 6: 197.) 
Lepidium virginicum. MAsTUERZzO. 
This common North American cruciferous weed is not uncommon in some parts 
of Porto Rico. (Stahl, 2: 37.) 
Leria nutans. See Chaptalia nutans. 
Leucaena glauca. ACACIA PALIDA, HEDIONDILLA. 
Family Mimosaceae; a shrub 3 meters high. Valued for its wood, edible pods, 
and seeds. (Stahl, 3: 146.) 
A small tree, with characteristic clusters of long, thin pods, growing in open 
waste places, particularly in dry localities. It is said to withstand drought when 
all other vegetation withers, and is then sometimes eaten by domestic animals with 
bad results, especially in the case of horses. The skin and cuticular appendages are 
affected, the hair, including the mane and tail, fall out, and if the eating of the 
plant continues, even the hoofs drop off. It has been suggested that Leucaena 
may thus become valuable as a homeopathic remedy for baldness.
