made to Gnadalupe Island by a botaiiiRt. The next year appeared 

 Mr. Watson's admirable paper (Proc, Amer. Acad., vol. xi} on the 

 flora of this island and a list of Dr. ralnier's plants, of which twenty- . 

 one were considered new. 



Ten years afterward Mr. E. L. Greene spent a week {the last of April) 

 adding to the flora fifteen species, describing seven new species, and 

 publishing in 1885 (Bull. Oal. Acad., vol. 1) his notes, and a catalogue 

 of the flowering plants and ferns of the island. 



Mr. Watson separates the plnenogamous plants into five groups as 

 follows: (1) Introduced species, twelve; (2) species which range from 

 the I'acific to the Atlantic States, nine ; (3) those found in California 

 as far north as San Francisco, forty-nine ; (4) those only in southern Cali- 

 fornia, eighteen; (5) those peculiar to the island itself, twenty-one. 

 Ad<l to these an undetermined lleuchera and six ferns makes a total of 

 one hundred and sixteen Pha^nogams and Pteridophyta. Mr. Greene's 

 list enumerates one huiulred and thirty species, all except twenty-six 

 he had observed in his short stay upon the island. Probably six of the 

 fifteen added by Mr. Greene belong to the first grou]). Among tlie 

 present additions at least four have very recently gained a foot-hoUl 

 here, viz, MelUotm Indica, ^onchnft fmcrrimus, Snncda Torrei/ana, and 

 Centaurca Mcliteiiftis, making th(^ total number of introduced species as 

 twenty-two; one is to be added in the second group. In the third 

 group, Mr. Greene's list adds iive and ours three, viz, Tissa macro- 

 thrca, Thm pallida, and Triscfum harhaium, making the number of dis- 

 tinctly Californian speciies fifty-seven. 



In the fourth group the two (Jaetacew and two Graminca^ make the num- 

 berof southern Californian species twenty-two. Of the fifteen additional 

 species added by Mr. Greene btit one he described as now, another 

 proltably new. Dr. Palmer has at this time collected seventy-two spe- 

 cies, fourteen of which are additions to the flora of the island and four 

 are new. The total number of species now known on the island is one 

 liundred and forty-five. Of the thirty-four species first described from 

 this island but three have since been found elsewhere. The following 

 list so far as known is peculiar to the island:
