ISLAND FLORA NOTES.

Hemizonia Clementina. H. Streetsii Gray, Syu. Fl. Suppl, p. 

 451, not of Proc. Am. Acad. XII, 162. Hirsute, especially below; 

 stems erect or ascending, at length much branched and leafy to the 

 numerous corymbosely-crowded heads, 3-4 dm. high : leaves linear, 

 obtuse or acute, attenuate to the base, 4-8 cm. long, entire or with a 

 few short teeth: heads 8-10 mm. high; involucral bracts linear, 

 those of the receptacle about 15, slightly united below; rays 14-20, 

 5 mm. long; disk flowers numerous: akenes of the ray rugose-tuber- 

 culate at maturity, indistinctly triangular, with an upturned beak, 

 and stipe 1 mm. long, those of the disk sterile, bearing a pappus of 

 about 10 subulate-linear palese, unequal in length and width. 



This species grows upon San Clemente and Santa Catalina Islands, 

 It was referred by Dr. Gray to H. Streetsii of San Benito Islands, 

 who considered the smaller plants from/these islands " dwarf and 

 early specimens." The living plants of these two species are strik- 

 ingly different, and at first sight of those on San Benito, I was certain 

 they could not be the same as those from the more northern islands. 



H. Clementina on San Clemente Island seemed to me to be a 

 semi-shrubby perennial, with many stems from the root; while H. 

 Streetsii is an annual six to ten inches high, with a single stem, 

 although I have seen one or two plants having an indurated root 

 and prostrate spreading habit, that might have been more than a 

 year old. H. Streetsii has simple stems branched above, the head? 

 not so crowded, rays longer and more conspicuous, leaves shorter 

 and more obtuse, more coarsely toothed, and with an auriculate 

 clasping base. 



On Todos Santos Islands, a shrubby Hemizonia is very common. 

 It seems to be the same as specimens named H.frutescens Oray,
