 mucronate, and tbe flowers are sparse.

 nee spirillifero nee mucilaginoso ! — Mesa San Juan, soutbern borders 

 of Colorado or adjacent part of Utali, T. S. Brandegee, in Ilayden's 

 Exploration of 1875. Dedicated to tbe indefatigable explorer and geo- 

 logical surveyor, in charge of this and many other successful explora- 

 tions of our Rocky Mountain regions. Tbe species has the habit and 

 color of corolla of the Eugilia division, but the long narrow corolla and 

 bractless pedicels of Ipomopsis. 



GiLiA Brandegei. Eugilia, perennis, pube glandulosa fragrante 

 viscosissima ; caulibus erectis spithamajis vel subpedalibus thyr- 

 sifloris; foliis circumscriptione linearibus pinnatisectis, segmentis 

 plurimis sessilibus parvis aut oblongo-linearibus rarius ovalibus inte- 

 gerrimis aut bipartitis verticillos 3-4-foliolatos simulantibus ; corolla 

 aurea infundibuliformi-tubulosa calyce cylindraceo semiquinquefido 

 2-3-plo longiore, fauce parum ampliata, lobis ovalibus brevibus ; ovulis 

 in loculis paucis. — South-western part of Colorado, in San Juan Gap 

 on the face of perpendicular cliffs, T. S. Brandegee, in Ilayden's 

 Exploration, 1875. A showy as well as most remarkable species, 

 with trumpet-shaped golden-yellow corolla, about an inch long. Leaves 

 2 or 3 inches, and their divisions only one or two lines in length. 

 The likeness of this plant in folinge, flowers, and fragrant viscosity to 

 Polemonium confertum var. melUtum is most striking. That species is 

 itself sufficiently anomalous in Polemonium, on account of its lengtli- 

 ened corolla ; but its filaments are really declinate-curved, while they 

 appear to be not at all so in the present plant. If this character be 

 relinquished, nothing will be left absolutely to distinguish either 

 Polemonium or Loeselia.
