causing it to be considered with the smaller forms. I have seen a 

 single well-grown plant which covered three to four square meters 

 of ground with the tips of its stems 3-6 dm. above the ground. 



Artemisia microcephala. 



Perennial herb about 6 dm. high with several erect paniculately 

 branching stems, whole plant flocculently white-tomentose : upper 

 leaves linear- to narrowly oblong-lanceolate, 1-3 cm. long, 2-5 

 mm. broad, tapering both ways, entire, acute though occasionally 

 3 -toothed at the apex, lower leaves often 3-5-lobed, 4-5 cm. long 

 and 6-9 mm. broad : heads in a bracted terminal panicle, numer- 

 ous, smaller than any in the group to which the plants belong, 3 

 mm. high and 2 mm. in diameter, 1 5-20-flowered : flowers very 

 small, yellow, about half in each head with much reduced tubular 

 corolla and pistillate, the others hermaphrodite and with normal 

 tube : akenes glabrous and without pappus, about 1 mm. long.

 gnaphalodes Nutt. Also collected at Albuquerque, N. Mex., in 

 the fall of 1894 by President C. L. Herrick of the New Mexico

The following described plants, all but two of which are from 



; ew Mexico, may properly be published along with those preced- 



m g although not collected on the trip referred to above. The two

her plants are known.
