   Geum triflorum Pursh var. ciliatum (Pursh) Fassett
   

3. Geum triflorum Pursh var. ciliatum (Pursh) Fassett in Rhodora 30: 207. 1928, PH-LC 99 (Moulton 75). (Rosaceae) - ciliated old-man's whiskers. Collected on the Weippe Prairie in Clearwater Co., Idaho, on 12 Jun 1806. Synonymy: Geum ciliatum Pursh.

   

   

   

   Grindelia squarrosa (Pursh) Dunal
   

4. Grindelia squarrosa (Pursh) Dunal in Mém. Mus. Hist. Nat. 5: 50. 1819. (Asteraceae) - curly-cup gumweed. PH-LC 100 (Moulton 76a), PH-LC 101 (Moulton 76b) and PH-LC 102 (Moulton 76c). The first two sheets were collected at Tonwontonga, a large Indian village in Dakota Co., Nebraska, on 17 Aug 1804, but only the two, centrally positioned specimens on PH-LC 101 appear to be Lewis and Clark material. PH-LC 102 is a mixed collection being composed of an 1811 Thomas Nuttall specimen (left-hand specimen) and probably a Lewis and Clark element (right-hand specimen). The two outermost fragments on PH-LC 101 are similar to the Nuttall fragment on PH-LC 102; it is suggested that the two small, flowering fragments on 101 are actually additional pieces of the 1811 Nuttall collection. Synonymy: Donia squarrosa Pursh.
