BORRAGINACE^. 
LiTHOSPERMUii LONGiFLOKUM, Sprciig. From Southern Texas to Western 
Illinois, Wisconsin, and the Saskatcliewan, and westward to Sonora, New 
Mexico, Colorado and the Rocky Mountains. Only on the foot-hills near 
Salt Lake City, rare; 5,000 feet altitude; May. (838.) 
LiTHOSPERMUM PiLOSUM, Nutt. Pi. Wyeth., Jour. Acad. Phil., 7. 43. 
{L. Tuderale, Dougl. Hook. Fl. Bor. Amer., 2 89.) Stems 1-1 J° high, her- 
baceous, strict, numerous from a perennial root, simple or branched above, 
hirsute, sulcate ; leaves 1-3' long, numerous, sessile, linear or linear-lanceo- 
late, acuminate but mostly pointless, strigose and somewhat hispid ; spikes 
very leafy, short and terminal ; flowers nearly sessile ; calyx hirsute, 5-parted, 
lobes unequal, linear ; corolla dull greenish-yellow, 3-4" long, villous, the 
broitd cylindrical tube equaling the calyx, the lobes rounded ovate ; throat 
naked but with somewhat prominent folds; nutlets large, 2" in length. — A 
well-marked species, but including L. Torreyi, Nutt., /. c, as represented by 
an original specimen in Herb. Torrey. Washington Territory, (Douglas, 
Wyeth.) Frequent in the lower canons, from the Washoe Mountains, 
Nevada, to the Wahsatch ; 5-6,500 feet altitude ; May-July. (839.) 
295 Parry and 441 Hall & Harbour, (referred to this species,) are the 
same as 627 Fender, (X. muUiflorum, Torr., Ms. in Herb.,) 1562 Wright, at 
least in part, and 442 Fremont, 1843, having slender branched stems 1-1 P 
high, with broadly linear subacute leaves, the yellow flowers nearly sessile in 
terminal elongated racemes, 6" long, the tube much exceeding the linear sepals; 
nutlets Ih" long, smooth and shining, (dull and scabrous in one of Wright's 
specimens.) This seems to be the L. incisum, Torr., of James's collection. 
L. decu/nbens, Torr., of that collection, is L. hirtiwi, Lehm.

lut<-lanc(M.late, for the most part obtuse; calyx 5-parted or deeply 5-cleft, 
the segments lanceolate or linear, acute, ciUate or nearly smooth, about half 
the lenirth of the corolla-tube, which is glabrous within and 2-3-times longer 
than the 5-clert lind) ; filaments dilated, as broad as the anthers or broader, 
but less in length.— Leaves nearly glal^rous, often somewhat glaucous, more 
or less scabrous upon the margin with short stiff curved hairs, and occasion-
