26. Eryngium oblanceolatum C. & R., sp. nov. 
Erect and tall, 3 to 6 dm. high, dichotomously branching; basal 
leaves oblanceolate, tapering into long petioles, from spinosely serrate 
to cleft, the teeth or small segments continuing down the petiole; 
heads on very short peduncles, nearly globose, about 6 mm. long; 
bracts very narrow and rigid, much longer than the heads, 18 to 20 
mm. long, the lowest third with spinose bristles, conspicuously sea- 
rious-margined at base; bractlets very narrow and rigid, much longer 
than the flowers, about the size of the bracts, with conspicuous scarious 
margin below (broadening upward toa lobe on each side), at the top 
of which and sometimes above are a few bristles: sepals ovate, searious- 
margined, 1.5 mm. long, tapering above into a short apiculation: stvles 
longer than the sepals.

Eryngium aristulatum Jepson, Erythea 1: 62. 1893. 
Prostrate, very slender, the stems 2.5 to4 dm. inleneth; basal leaves 
tapering into a long petiole, 1 dm. long (including the petiole). the 
short blade spinose-toothed and with a few lanceolate segments: stem 
leaves opposite, sessile, spinulose-serrate; heads very numerous, 6 mm. 
long; bracts exceeding the head, about 10 mm. long, densely spines- 
cent at base; bractlets spinose, the hody narrowly lanceolate, inversely 
sagittate-winged from the base upward, the lobes of the wings thus 
forming sinuses, in each of which are borne 1 to Bawns surpassing the 
breadth of the wing; calyx-lobes ovate-lanceolate, hyaline-margined, 
2mm. long, tapering into a cuspidate-bristly tip exceeded by the long 
styles.
