Acacia amentacea DC. Prodr. 2: 455 (1825). 



Acacia rigictula Benth. Lond. Jour. Bot. i : 504 (1842). 



Usually a low, gnarled and twisted branching prostrate shrub at Corpus 

 Christi, altitude 10-35 feet, beginning to flower before the leaves appear. 

 Very spiny. Sometimes erect and spreading. 



March 5 -(1382) ; type locality, " in Nova-Hispania." Mexico. 

 Acacia Farnesiana Willd. Sp. PI. 4: 1083 (1806). 



A handsome tree with smooth brown bark, much cultivated at Corpus 

 Christi, but growing wild about the town, on the bluff portion, altitude 

 20-40 feet. The flowering heads on the specimens collected were only 

 slightly odorous, rather small and lax, scattered. 



March 17 (1454) ', type locality, " in Domingo." 

 Acacia Roemeriana Scheele, Linnaea 21 : 456 (1848). 



One of the most common shrubs on the hills about Kerrville, usually 

 confined to near and on the summits, at an altitude of 1900-2000 feet. 

 The original description calls for " flores rosei," perhaps owing to dis- 

 coloration in the dried specimens. They are tawny white. Schlechten- 

 dahl instead of Scheele, is often given as the author of this species. 



April 23 in flower, in fruit May 22 (1624); type locality, " prope 

 Austin." 

 Acacia tortuosa Willd. Sp. PI. 4: 1083 (1806). 



Growing in company with, and flowering at the same time as A. 

 amentacea. A prostrate, much-twisted, spreading bush, the orange yel- 

 low flowers of which are delightfully fragrant. The numerous heads are 

 on slender, glandular peduncles an inch long. Spines over an inch long, 

 whitish, at least the older ones. The pods are from two to four inches 

 long, usually curved, linear, flat, with flat edges a line or two wide, 

 tomentose, covered especially along the sides with cherry-colored glands. 

 Flowering specimens of this have, no doubt, often been confused with 

 A. Farnesiana. I took it to be that species until I found it in fruit. 



March 5 (1383); type locality, West Indies. 



MIMOSA L. Sp. PI. 516 (1753). 

 Mimosa fragrans A. Gray, Bost. Jour. Nat. Hist. 6: 182 (1850). 



Frequently met with along the stony banks of the Guadalupe and on 

 hillsides at Kerrville, ranging from 1625-1900 feet altitude. A shrub 

 3-6 feet high, with slender, flexuous branches, bearing an abundance of 

 pale rose purple flowers, which fade almost white when old. The pod 

 is occasionally armed with scattered prickles. 



April 19 in flower, May 20 in fruit (1594); type locality, "rocky 

 soil on the Pierdenales," a stream eighteen miles north of Kerrville.
