que substantia resinosa spissa ochroleuco-nitentibus. Internodia superiora vix 3-4 lineis longa. 
Folia linearia subcarnosa puberula, sulco superne longitudinali, dorso rotundata; caulina 
interdum pollicaria, ramealia 3-6'" long deorsum incurva. Capitula in apice conferta 
breviter pedicellata. Squamis involucralibus carinatis, filiformi-mucronatis, flavescentibus. 
Stem erect 2-3 feet high, fastigiately branched, with crowded heads on short pedicles, forming 
a corymb. The whole surface of the stalks is covered with a short, apparently dense, tomentum, 
infiltrated with a yellowish resinous substance, giving it a texture of ear-wax of a greenish- 
golden hue. Internodes of the branchlets 3-4 lines. Leaves linear, puberulent, subcarnose, 
rounded on the back, with a furrow on the upper surface, about one inch long on the stem, 
half an inch or less, and recurved on the branches. Scales of the involucre carinate, light 
yellow, darkening towards the filiform mucro. Tejon Pass ; September. 
Linosyris teretifolia, ( nova species.) Fruticulus 8-12 pollicaris corymbosus, ericas facie, 
resinoso-vernicatus, balsamum canadense redolens, cumuliformis fruticeta que vasta sistens. 
Trunculi emarcido-grisei, ramulis ochraceis punctatis, internodiis brevibus, naviculato-depressis, 
marginatis, filiformibus dense foliosis. Folia ^-1-pollicaria filiforme-teretia obtusa, superne 
pauxillum sulcata, aeque ac ramuli, fusco-viridia et epidermide maxime viscido-resinosa 
induta. Capitula flava in summo spiculata subsessilia, squamis involucralibus obtusis apice 
glanduloso-gibbo. 
A small shrub, strongly varnished and smelling of fir balsam, covering extensive tracts of 
land, like the common heath of Europe, and presenting a corymbose summit darkly-green with 
filiform, erect, dotted and scabrous leaves and branches, both alike, with crowded yellow heads 
of flowers. The lower branches have a grey and mealy, the upper a bright ochre-yellow dotted 
rind, with the internodes navicularly depressed and costately bordering ridges. Leaves obtuse, 
1-1J line long. Heads of flowers subsessile, aggregated into dense terminal spikelets and 
clusters, forming a corymb. All over the mountains around Tejon valley ; September.
