mote and smaller on the flowering branches, oblong-lanceo- 
late, obtuse or exceptionally acute, undulately low-serru- 
late, narrowed or abruptly contracted and then cuneately 
narrowed into short petioles; flowers produced in long suc- 
cession along the elongated branches, erect, pale, barely 
5 mm. long; fruiting peduncles about 10 mm. long and 
equalling the leaves; seeds short-beaked, very finely papil- 
late, .4 x 1 mm.; coma white or somewhat dingy. — Cali- 
fornia: San Bernardino county (Parish, 1881, no. 1022) and 
Kern county (Heermann, Aug. 1853, in Hb. U.S. Dep. 
Agr.). Possibly also Mariposa county ( Congdon, 1882 ).—

Innovations have not been seen by me, and Mr. Parish 
considers the plant to be probably annual. In pubescence 
it most nearly approaches 4. Watsoni, while the rosy 
flower-buds are somewhat as in #. Californicum. 
E. ADNATUM, Griseb. (Z. tetragonum of most old world writers, but 
not of Linnzus nor of American botanists), a large European species 
collected on ballast near Philadelphia (Martindale, June 1878, in Hb. 
U. S. Dept. Agr.), is related to the last in being pubescent above with 
short closely appressed straight white hairs, and in having its rather 
acute sharply serrulate leaves typically oblong with nearly parallel mar- 
gins; but it differs from all of our rosuliferous species in that some of 
the leaves are broadly sessile with the margins decurrent on the stem into 
prominent subglabrous lines. Its seeds are very rough. 
16. E. Fenpteri, Hausskn. — Slender, virgate, little 
branched, the inflorescence and flowers cinereous with in- 
curved hairs; leaves 25 to 75 mm. long, narrowly lanceo- 
late, acute, rather sharply low-serrulate, gradually nar- 
rowed to very short winged petioles ; seeds with very short 
scarcely pellucid beak, .8 x 1 mm. ; coma white.— Monogr.

knecht; Wright, 1851, no. 1065 in part, and 1849, no. 
953, — in Hb. Gray., not distributed). — Plate 18. 
b. Broader-leaved, the foliage often purple in autumn. 
17. E. cotoratum, Muhl. — Glabrate below, the rather 
numerous panicled branches canescent with incurved hairs 
at least along the decurrent lines, and more or less glandu-
