COULTER AND ROSE—-NORTH AMERICAN UMBELLIFERAE, 55 
We have not been able to reexamine the type of 1. minimum, and therefore can 
not refer FE. articulatum microcephalum to it with certainty. An examination of 
specimens from the type locality of /. minimum, however, together with a reexami- 
nation of the type of M. articulatum microcephalum, seem to justify this tentative 
reference, although the sepals of tne latter are somewhat different, and the heads 
have a decidedly bluish tint. 
24, Eryngium alismaefolium Greene, Erythea 8: 64. 189. 
The numerous leaves and stems clustered at base and arising from 
a fascicle of coarse roots; stems diffusely branching, at first much 
shorter than the leaves, later often exceeding them; basal leaves 
elongated, sometimes 3 Gm. long, the long more or less nodose petioles 
(nodose ones terete and not spinose, the others flat and spinose) with 
or without spinosely serrate or somewhat laciniate oblanceolate blades; 
upper leaves similar, but much smaller; heads usually on short pedun- 
cles, nearly globose, 9 to LO mm. high: bracts subulate-lanceolate, 
usually somewhat longer than the heads, LO to 12 mm. long, with or 
without a few spinose bristles, somewhat scarious-margined at base; 
bractlets subulate-lanceolate, a little exceeding the flowers, with con- 
spicuous searious margin below (broadening downward), with or with- 
out a few bristles; sepals ovate-oblong, scarious-margined, | mi. long, 
tapering into a cuspidate-bristly tip: styles longer than the sepals.
