A DECADE OF NEW GUTIERREZIAS. 55 
'l'his is Mr. Wooton's n. 449, from the Organ Mountains, 
New Mexico, distributed, with my approval, as G. lucida ; 
but this was too hastily done. The plant has, indeed, the 
subcylindric 2-flowered involucres of the Californian species; 
but it has not the yellow-green somewhat shining herbage 
which suggested the specific name lucida; nor is it gla- 
brous ; and its foliage is ascending on the stems, while that 
of G. lucida is deflexed. 
G. riLIFOLIA. Size and habit of the last, but herbage 
dark-green and hirtellous-scabrous, the leaves ascending, 
linear-filiform, nearly 2 inches long; heads in a rather 
loose panicle, a few sessile, but most of them on short fili- 
form pedicels: involucres narrowly obovoid, the long inner 
bracts obtuse and merely green-apiculate, the outer and 
shorter with thick green tips: flowers of ray and disk 3 or 
4 each, or those of the disk sometimes 2 only, the rays long 
for the genus. 
White Mountains of New Mexico, 24 August, 1897, at an 
altitude of about 5,000 feet, on what is called Round Moun- 
tain, collected by E. O. Wooton; apparently not distributed, 
my sheet of specimens having no number attached. By 
the number of flowers to the head this would be at agree- 
ment with G. microcephala, which, however, is a Mexican 
species quite different from this in important points. 
G. TENUIS. Shrubby below the middle, the whole tuft of 
slender stems nearly two feet high, the leaves and twigs 
sparsely scaberulous; branchlets of the fastigiate-corymbose 
inflorescence very slender: leaves all narrowly linear and 
plane, scarcely more than } line wide: heads mostly pedi- 
cellate, or the terminal ones sessile in pairs or threes; in- 
volucres obovoid, 1} lines high, their bracts in three series, 
the inner broad and very obtuse, inclined to be scarious- 
margined at summit rather than green-tipped, but the short 
outer ones less obtuse and with erect green tips: ray-flowers
