Morongm angustata (Torr. & Gray) Britton. Sensitive Briar. 

 (Schrankia angustata Torr. & Gray) "Ten vergiienza". 



Similar to Morongia roemeriana but mature pods are over 

 two inches long and leaves have six to sixteen divisions instead 

 of four to eight. Named for Schrank, a German botanist. 



Mimosa fragrans A. Gray. Pink Mimosa. Sensitive Shrub. 



A prickly, much branched shrub with lovely rose-colored 

 fuzzy balls of bloom, similar in size to the blossoms of huisache. 

 Leaves twice compound, each of the two to six divisions bearing 

 ten to sixteen small, entire, sensitive leaflets. Pods curved, one 

 to two and one-half inches long, with constrictions between the 

 three to eight seeds, the margins rarely armed with stout prickles. 

 March and April. Usually on lower ledges of limestone bluffs. 



Prosopis juliflora (Swartz) DC. Mesquite "Mezquite" 



San Antonio's commonest tree. It usually has one main 

 trunk and a fairly broad and usually open crown. Branches 

 armed with straight spines. Leaves feathery, drooping, twice 

 compound, each of the two (rarely 4) divisions bearing ten to 

 sixteen pairs of narrow, entire leaflets about one inch long. 

 Flowers in cylindrical spikes, one and one-half to three inches 

 long, white turning yellowish with age. Pods variously colored, 

 nearly straight or curved, narrow, somewhat flattened, four to 

 twelve inches long, containing oblong seeds and hanging in 

 clusters from the tips of the main branches or the numerous 

 twigs. March and April and again in June and July. Pods 

 form nutritious food for stock. 



Mexican children often eat the pods, which are sweet. They 

 used to be an important food of the Indians.
