S. Fareisii (Baker). Frutex ramosissimus ramis flexuosis virgatis 
albido-canescentibus, foliis confertis anguste linearibus uniiiervis 
integris margine revolutis herbaceis supra subglabris infra albido- 
canescentibus, capitulis paniculatis, involucris tubuloso-campanu- 
latis viridibus paulo canescentibus squamis 10 — 12 ligulatis 
sequalibus basi paucis linearibus minimis bracteatis, floribus circiter 
20 omnibus discoideis homogamis involucre longioribus, achsenio 
pubescente, pappo flore equante. 
A native of Peru, sent by Mr. Farris. 
A copiously-branched bush two to three feet high, with slender 
flexuose terete branches clothed upwards with a thin coating of 
white cottony pubescence. Leaves crowded, ascending, narrow- 
linear, two to two and a half inches long, not more than a line 
broad, one-nerved, the edge entire, revolute ; texture herbaceous ; 
upper surface green, subglabrous ; lower clothed with thin white 
cottony pubescence like the stem. Floiver -heads in sparse regular 
thyrsoid panicles at the end of the branches. Pedicels one to six 
lines long, with small linear bracts at the base. Involucre 
tubuloso-campanulate, four lines deep, sparsely downy, con- 
sisting of ten to twelve equal ligulate scales, pressed closely edge 
to edge, bracteated at the base with a few minute linear ones. 
Floiver s all tubular and perfect, about twenty to a head, one- 
fourth longer than the involucral scales. Achcenimi pubescent. 
Pappus dense, white, equalling the corolla. 
Closely allied to S. Humboldtianus, D.C. Prodr. vi. 421, with 
which it coincides in its general habit, and homogamous flow^ers, 
but a more slender plant, with leaves much less firm in texture, 
and, like the branches, less densely coated with cottony pu- 
bescence ; the involucre much narrower, containing not more 
than half as many flowers.
