Eriophyllum arachnoideum (F. & L.) Greene 



No. 8584, collected May 28, about two miles beyond San 

 Mateo, San Mateo county, on the Half Moon Bay road, eleva- 

 tion 100 feet, on a grassy sparsely wooded slope, and not uncom- 

 mon in the vicinity. It is a much thinner leaved more erect 

 plant than is my idea of this species, and the disk corollas do 

 not have a "very glandular-hirsute tube" as described by Greene, 

 but are granular. 



Lasthenia glabrata DC. in Lindl. Bot. Reg. pi. I'jSo. 1835. 

 No. 8598, collected May 30, in Hall's valley, Santa Clara 

 county, elevation 1500 feet, growing in rich damp soil in low 

 ground, and abundant at one place near the Mt. Hamilton road. 

 The leaves are all narrow, entire, the lowest dilated and connate 

 at base, the uppermost little if any dilated, meeting but not con- 

 nate. 



ANTHEMIDACEAE fam. nov. 

 Annuals, or perennial herbs, or shrubs, mostly aromatic 

 scented, with bitter juice: leaves usually much dissected: invo- 

 Incral bracts imbricated, more or less scarious: ray flowers either 

 present or wanting: receptacle either naked or chaffy: anthers 

 not caudate: style branches of perfect flowers truncate, some- 

 times penicillate: achenes small and short, the pappus a circle 

 of small scales, or wanting. A family composed of the genera 

 included under the tribe or subfamily Anthemideae of the fam- 

 ily called Compositae. 



Achillea lanulosa Nutt. Journ. Phila. Acad. 7: 36. 1834. 



- No. 8589, collected May 30, near Smith Creek, Santa Clara 

 county, elevation 2150 feet, on grassy slopes about thickets in 

 gravelly ground. The type was collected by Wyeth in the 

 Rocky mountains, and it is doubtful whether our plant is the 

 same, since several forms are found in the State.
