STANDLEY TREES AND SHRUBS OF MEXICO. 311 



ftecause of the yellow color of the flowers. The stems of both are round, 

 purplish, woody, brittle, and slender, with soft pith. In form and odor the 

 flowers are not unlike the musk rose, a plant not wholly different from this one. 

 The leaves are like those of the bramble, but less toothed, with nerves running 

 lengthwise, and with almost the odor of cucumber. The flowering branches are 

 employed for their perfume by the Indians, and for the garlands which they use 

 so much; and a scented water of pleasant odor is distilled from them. The 

 plant grows in temperate or rather cold places. The leaves are bitter and dry 

 and hot in almost the third order, wherefore, if taken in wine in the quantity 

 of a handful, they relieve colic, and if crushed and applied as a plaster, they ease 

 strained members, and dissolve tumors beyond belief." Hernjindez also gives an 

 illustration,^ without description, of the " cozticacuilotl xochitl."
