Truckee Eiver. The cotyledons axe cleft nearly to the 

 base. 



E. Austhim differs from the common form in its very 

 slight or obsolete torus rim. Its cotyledons are entire or 

 one cleft and the other entire. 



E. fenuiseda I have not seen. From the description, it 

 approaches the annual forms elegans and peninsidaris, and, 

 like them, has cleft cotyledons. 



E. ParisMi was described from small flowering specimens 

 only. 



E. elegans. — The annual form corresponding to E. Ausiince. 

 Cotyledons entire or one of them cleft. 



E. peninsidaris. — Exactly the ordinary form of E. Califor- 

 nica, but annual. Cotyledons shortly cleft or merely 

 notched. 



E. Ifexicana — The annual representative of the form de- 

 scribed as E. lei^tandra. I have not seen mature fruit. 



E. rhomhipetala — of which E. Lemmoni, judging from the 

 ■description, is a more elongated-scabrous and less scapose 

 variation — is one of the most peculiar forms and perhaps 

 separable as a variety when better known. It has usually 

 entire broad cotyledons. 



E. ramosa has entire or barely notched broad cotyledons. 

 Some specimens from Santa Cruz Island are only a few 

 inches in height, branching from the base; and a straggling 

 form has been collected on San Clemente. It is not 

 "strictly maritime, growing only within reach of the sea 

 spray;" Mr. Braudegee found it in abundance near the 

 summit of Santa Cruz Island. 



E. glyptosperma. — The seeds are not really pitted, as may 

 be seen by examination of the immature ones; the retic- 

 ulations are covered, as well as nearly all of the intervals, 

 by a gray scurf, like that which appears in many of the 

 other forms.
