ligules were wliile and numerous. In Pringle's spécimens Ihere are 

 aboul len ray-florels. If, Ihen, it be assumed, as Ihe évidence seems lo 

 warrant, Ihat Lexarza drew iip his description from dried and somewhat 

 shrivelied spécimens, laid in afler collection, his characlers of narrow 

 leaves, and linear ligules in two or Ihree rows, may be somewhat dis- 

 counted, when one considers the wilhdrawal of moisture and shrinkage 

 in the process of drying. Apart from Ihe color of the ligules, Lexarza's 

 description fits n. 4921 from Oaxaca better than n. 4099 from Michoacan. 

 From fuller material than was available when Mr. B. L. Robinson drew 

 up his English description, l give the foUowing description, drawn iip 

 in Latin, in which certain minor points in the character of the species 

 are noted, and omitting ail generic characters.
