' With the hope of finding in Bering Strait the expeditions under Parry 

 and Franklin, the British Government in 1825 dispatched H. M. S. Blossom 

 under the command of Capt. F. W. Beechey. This ship anchored at San 

 Bias in Tepic in December, 1827, and i*emained there until February, 1828. 

 During this time the naturalist. Lay, explored Tepic and adjoining regions, 

 and made a collection of plants. Some of these came from Jalisco, and 

 on the labels that name was written " Talisco," a circumstance which has 

 caused a derivative of the latter incorrect name to be used as a specific 

 name for some of the new species described from the collections. Plants were 

 collected also at Acapulco and Mazatlan. Some of the naval ofl^cers, par- 

 ticularly Alexander Collie, assisted Lay in making the collections. The 

 plants were reported upon by Hooker and Arnott.
