'PI. Nov. Hisp. 51. 1887. ' 



'Named in honor of Thaddeus Haenke" (1761-1817), a Bohemian. He was 

 to have accompanied the Malaspina expedition executed during the reign of 

 Charles III, but he reached Cadiz the day after that organization had set sail. 

 He took another' ship and sailed for Buenos Aires, proceeding to Chile, where 

 he joined Nee, and with him journeyed to Mexico. Haenke's Mexican collec- 

 tions were made along the road from Acapulco to the City of Mexico. He died 

 in Bolivia. His specimens are chiefly at Prague and Vienna. Presl published 

 two volumes under the title •' Reliquiae Haenkeanae," based upon his col- 

 lections.
