A somewhat immature specimen collected by Jepson, May 28, 1897, at ‘“ Wells 
may belong here, but it has narrower 
? 
Hill, Upper Vaca Valley, Napa River Basin,’ 
and less spinulose leaves and smaller heads and bracts. 
29. Eryngium jepsoni ©. & K., sp. nov. 
Erect, 3 to 6 dm. high, from almost simple to much branching; basal 
leaves narrowly oblanceolate, tapering into long petioles, spinose- 
toothed and sometimes with a few narrow segments; upper leaves 
opposite, short-petioled or sessile; heads on very short peduncles, 
nearly globose, about 6 mm. long; bracts very narrow and rigid, much 
longer than the heads, 8 to 20 mm. long, the lowest third with spinose 
bristles, hardly scarious-margined at base; bractlets narrowly linear- 
lanceolate, a little longer than the flowers, with conspicuous scarious 
margin below (broadening upward to an acuminate tip or lobe on each 
side), at the top of which and just above area few bristles: sepals 
oblong, scarious-margined, 2 mm, long, with an abruptly cuspidate- 
bristly tip about one-third as long; styles longer than the sepals.

lected by W. LZ. Jepson in 1805; type in U.S. Nat. Herb,

BE. articulatum inicrocephaluin C. & Re 1. ce. 99. 
Low, 1 to 3 dm. high or even less, leaves and the few nearly simple 
stems clustered at base; basal leaves narrow, with more or less elon- 
gated petioles, from simple and spinosely-toothed to pinnately-seg- 
mented; the segments from toothed to lacerate or pinnately-parted, 
more or less distant below and represented on the petiole by spinous 
processes; heads on very short peduncles, nearly globose, about 6 mm. 
long; bracts linear-lanceolate, as long as the heads or a little longer, 
6 to LO mm. long, the lower two-thirds with spinose bristles, hardly 
scarious-margined at base; bractlets linear, a little longer than the 
flowers, with conspicuous scarious margin below (broadening down- 
ward), at the top of which and just above are a few bristles; sepals 
ovate, scarious-margined, 1mm. long. with an abruptly cuspidate- 
bristly tip about as long; styles longer than the sepals.
