F. btpmnatifida -wdiS first described in " Linnea " as variety 

 bipinnatisecta of F. Chamissonis, and it may yet again be 

 restored to its former position when all the forms are belter 

 known. Each of these is represented on San Nicolas, both 

 differing from each other and the typical forms. One 

 seems to fall under F. Chamissonis while the other is nearer 

 F. bipinnatijida. 



It is with hesitancy that I describe these forms as new 

 varieties even ; but after much deliberation it seems the 

 best course. 



77. Franseria Chamissonis Less., var. viscida, var. nov. 



Stems stout, striate, loosely villous with white hairs, viscid ; leaves 

 extremely variable ; upper ones oblanceolate and entire to ovate-spatulate, 

 cuneate at base, crenate-dentate ; lowest leaves broadly ovate in outline, 

 deeply parted with divisions crenate-dentate or incised and even becoming 

 bipinnatifid ; pubescence sericeous, dense, and appressed : sterile involucres 

 5 mm. in diameter, almost sessile ; fruit with keeled, and channeled, spread- 

 ing spines viscid even to the apex. 



It is the viscid character of the spines to which the name 

 is due. 



78. Franseria bipinnatifida, var. dubia, var. nov. 



Stem ribbed, less villous and viscid than the preceding ; leaves broadly 

 ovate in outline, bipinnatifid with divisions about 2 mm. broad, silvery silky 

 with appressed hairs but less dense than the preceding ; sterile heads 6 mm. 

 in diameter on slender pedicels 4-8 mm. long ; fruit with spines slightly vil- 

 lous and viscid. 



Mrs. Trask notes these two as common on the sand-hills 

 and as keeping their peculiarities even when growing 

 together. 



79. Baccharis consanguinea DC, ? Prodr., Tome V., 

 p. 408. " California, Douglas." 



This is reported as the only tree and but one individual. 

 It more properly ought to be considered as an arborescent 

 shrub. It grew to a height of seven feet on a fertile flat. 

 There were no signs of fruit or flower, so, though the foliage
