minute hairs on the achenium are glochidiate. 
GYMNOsPERMA conYMBOSUM, DC. Prodr. 5, р. 312. Along the Rio Grande. All three of De

Bigelow. 
LINOSYRIS ARBORESCENS, (sp. nov.): glabra, viscidula ; caule 10-pedali lignosa ; ramis apice 
cory mboso-polycephalis ; foliis anguste linearibus acutis, ramulorum subulatis; involucro 
pauciseriali disco breviore 20—25-floro, squamis lanceolatis acutis carinatis margine scarioso- 
ciliolatis; appendicibus styli lanceolato-subulatis portionem stigmatiferum equantibus ; 
acheniis brevibus turgidis pubescentibus.—California ; Rev. Mr. Fitch. The flowering branch- 
lets in Mr. Fitch's collection are stated to belong to **a tree 10 feet high." They are slender 
and very leafy; the leaves are one or two inches in length, about a line wide, much like those 
of L. vulgaris, only a little viscid. Corymb crowded. Heads three lines long; the flowers 
all tubular, but occasionally a marginal one shows a tendency to become irregular, and to have 
its anthers abortive. Receptacle alveolate and toothed. Achenia all fertile, short-oblong,
