This sheet, Lewis 5 [probably 25, label is damaged; see Sorbus scopulina, No. 182 below], has long been misidentified. Meehan (1898: 30) reports the specimen as Lonicera involucrata (Richardson) Banks ex Spreng (Syst. Veg. 1: 759. 1825) and it has been variously annotated over the years, with Piper suggesting L. utahensis and L. ebractulata Rydb. (in Mem. New York Bot. Gard. 1: 372. 1900). We believe Piper is correct in that we regard the latter name to be a synonym of L. utahensis (fide Cronquist et al., 1984). Moulton (in press) lists the plant as L. ciliosa (Pursh) DC. (Prodr. 4: 333. 1830). There are two labels on the sheet, one giving the date as 16 Jul 1806 and a second as 2 Sep 1805. The latter is an original Lewis label with a collection number and a brief diagnosis. On 16 Jun 1806 the expedition was on the Lolo Trail in Idaho Co., Idaho (Moulton, 1993: 27-31). On 2 Sep 1805, they were in Lemhi Co., Idaho, traveling along the North Fork of the Salmon River from near the mouth of Hull Creek to near the junction of Hammerean Creek (Moulton, 1988: 183-185). The specimen seems to be of a proper developmental state for the September date.
