eaulibus (vel ramis) curvato-adscendentibus vel erectis 2-3 mm. 
crassis ut videtur paullulo lignescentibus inferne delapsu foliorum 
nudatis nodulosis superne densissime foliosis; foliis alternis saepis- 
sime in axillis proliferis deltoideo-ovatis profunde bipinnatifidis 
utrinque dense griseo-pubescentibus 2-3 em. longis et latis, lobis 
anguste oblongis vel oblanceolatis vix acutiusculis integris vel saepe 
lobatis; petiolo 5-12 mm. longo cuneatim alato; thyrso terminali 
solitario vel pluribus ovoideis densis ca. 3 em. longis 2.5 em. crassis; 
capitulis ca. 4-floris sessilibus vel breviter pedicellatis ca. 5.5 mm. 
longis; involucri squamis principibus plerisque 4 subaequalibus cum 
1-2 multo minoribus calyculatis viridibus tenuibus sordide pubescen- 
tibus; corollis albis ca. 3.2 mm. longis, tubo proprio glandulari- 
puberulo; limbi dentibus 5 ovato-deltoideis patentibus; antheris | 
apice omnino exappendiculatis basi subsagittatis; styli ramis fili- 
formibus subtruncatis apice paullo incrassatis; achaeniis (valde 
immaturis) hispidulis; pappi setis ca. 18 inaequalibus ca. 2 mm. longis 
scabratis.— Peru: in very arid ground, Posco, between Mollendo 
and Arequipa, 6 Aug. 1914, Dr. & Mrs. J. N. Rose, no. 18,805 (U. S., 
phot. and fragm. Gr.). This beautifully distinct species adds a third 
to the alternate-leaved section of the genus. In habit and cutting of 
the leaves it recalls the Brazilian Lomatozona artemisiaefolia Bak. in 
Mart. Fl. Bras. vi. pt. 2, 199, t. 54, f. II (1876), but of course differs 
from it significantly in many technical characters, such as its ex- 
appendiculate anthers, longer pappus, alternate leaves, etc.
