Eriogonum Pringlei, n. sp.—Woody, 3 dm. high, densely 
white tomentose, leafy throughout, with flaky bark, and 
many slender intricate branches above, each terminated by a 
loose paniculate spike (4 to 6cm. long), leaves linear, acute, 
very small (1 cm. long,) narrower toward the base, strongly 
revolute, often with smaller ones fascicled at the base of the 
branchlets: bracts very small, triangular to setaceous: in- 
volucres sessile, small (2 cm. long), 6 to 9, regularly distribu- 
ted, each containing 4 or 5 minute whitish or slightly rose- 
colored flowers (2 mm. long).— Rocky hills near Maricopa, 
Arizona, Pringle, in 1882, and distributed as ‘‘E£. Wrightii 
Torr., var., or a new species.” It is nearest to £. Wrightit 
Torr., but its flaky bark, many intricate branchlets, short 
linear revolute leaves, numerous spikelets with smaller and 
regularly arranged involucres and flowers, narrower and 
lighter colored sepals, and smooth achenes make it a very dis- 
Euphorbia Nealleyi, n. sp.—-Densely puberulent through- 
out; stems slender, erect or ascending (2 to 3 dm. high), 
branched or simple at the woody base, with few alternate 
1.5 mm. wide), entire, short-petioled, thickish, acute, se 
date; glandular stipules minute: involucres solitary, axillary 
and terminal, pedunculate, turbinate; glands 4, truasrore 
oblong, with large and white irregularly dentate annie 
appendages: style short: pod rather depressed, about 3 mm. 
broad: seed ovate-triangular, deeply and irregularly trans 
verse sulcate.—W. Texas (WVealley, 1890). This species 
belongs to § ALECTEROCTONUM except the leaves are simply 
Opposite and not ternate or verticillate. Its general appearance 
isthat of E. biformis Watson, but its stems are alternately 
branched and its seeds are strongly sulcate. It really seems 
to be somewhat intermediate between the sections Alecteroct- 
— and Zygophyllidium. :
