POLEMONIUM VISCOSUM Nutt. Journ. Acad. Phil. (II.) 1: 154. 1847. Not Gray.
In describing P. ViSCOS1t711, Gray* states that it has rounded calyx-lobes, and gives as reference: Pl. Gamb. 154 mainly, ex cluding what relates to the " elongated lanceolate segments of the calyx." The Plantae Ganzbellzi were published in the Journal above cited. Nuttall describes there the calyx-segments as being elongated lanceolate, both in the Latin description and in the gen eral notes written in English. In order to settle the matter I have written to the Curator of the Philadelphia Academy of Sciences, Mr. Stewardson Brown, who has kindly loaned me Nuttall's type. This is not a very good specimen, is past blooming, but it is satis factory for my purpose. It shows that the inflorescence was sub capitate or subspicate and that the calyx-segments were elongated lanceolate. On the same sheet as Nuttall's type there is ;Another specimen collected by T. S. Brandegee in the state of Washington; under the two specimens is penciled in the handwriting of the late Mr. Redfield the following remarks : " These all seem quite differ
ent from P. in the flowers and mode of flowering. Yet I cannot fit them to Gray's description of what he regards as Nutt all's P. ViSCOS1t712." From the more complete material I have at hand, viz.: speci mens collected by J. H. Flodman, no. 742, August 19, 1896, on the top of Long Baldy, Little Belt Mountains, and by Frank Tweedy, 1887, in Park County, Montana, I can easily see that P. ViBCOS1lm1 Nutt. is a near relative to P. coirfcrium Gray. It has the same general habit and inflorescence. The corolla is, however, shorter, more open-lunnelform and dark blue and the segments of the leaves are much smaller and rounder. The plant is very strong scented.
What Dr. Gray regarded as P. viscosum, I think I know, as there is a specimen in the Torrey herbarium, received from Dr. Gray and labelled in his handwriting. This specimen agrees also fully with Dr. Gray's description. It should be known under the name
