35. Gutierrezia laricina Greene, nov. spec. 
Planta humilis, propemodum , herbacea potius quam suffruticosa, e 
basi multicaulis, caulibus adscendentibus erectisve, 10—18 cm altis, 
usque ad inflorescentiam foliosissimis; foliis primordialibus 2 cm longis, 
anguste linearibus deflexis, ceteris multis axillaribus crebre fasciculatis, 
omnibus saturate viridibus, undique muriculato-scaberulis; capitula 
mediocria numerosa, in summo caule corymboso-paniculata; involucri 
obconici bracteis 12—15, adpressis, obtusis, apice manifestim herbaceo- 
incrassatis; flores radii 3-—5, disci circa 5; pappi paleis circa 7, oblongis, 
` acutis, achenio villoso aequilongis. 
Species known only from the low and torrid plains of the south- 
western part of the Colorado Desert in California. Being densely 
clothed, even of late flowering, with fascicles of larch-like leaves, its 
aspect is in marked contrast to that of all other Californian members of 
the genus. 
The specimens before me were collected by C. R. Orcutt, in 
October, 1889. 
36. Gutierrezia furfuracea Greene, nov. spec. 
Suffrutex 5 dm altus, et verisimiliter ultra, arbusculiformis, fasti- 
giatim ; ramosus, ramis rigidiusculis, angulosis furfuraceis, apice thyr- 
soideo paniculatis; folia linearia, brevia, adscendentia, integerrima; capi- 
tula, pro genere majuseula, in ramulorum brevium apicibus conferta; 
involucrum ovoideum, bracteis perpaucis coriaceis obtusissimis, apice vix 
incrassatis, undique resinoso-furfuraceis; flores radii 2— 3, pallide lutei, 
disci 3—5. 
Collected at Cactus Flat, in the region of the upper Rio Gila, south- 
eastern New Mexico, 13 October, 1908, by Mr, E. A. Goldman. 
37. Gutierrezia Goldmanii Greene, nov. spec. 
Suffrutex e basi lignosa late ramosus; rami annotini floriferi erecti 
simplices flexiles 2—3 dm alti usque ad inflorescentiam corymbiformam 
foliosi, foliis linearibus 2 cm longis, et ultra, angustis acutis adscen- 
dentibus, crebre et manifestim resinoso-punetatis, undique minutim hir- 
tellis; paniculi corymbiformis ramuli filiformes foliis numerosis linearibus 
subpatentibus vix 1 cm longis obsiti; capitula parvula conferta; involucri 
obovoidei bracteis 8—10, obtusissimis, apice nunquam incrassatis aut 
herbaceis; flores radii circa 5, ligulis aureis valde elongatis, disci 3—4;
