204 BORRAGLNACE.E. Lithospermum. 



length elongated-linear calyx-lobes : " roots bearing oblong tubers." DC. Prodr. x. 76 ; 

 Chapm. Fl. 332. Florida, on rocky river-banks, Ruyel, Chapman. Texas, Wrinht, Lind- 

 heimer, only in fruit. Larger leaves at length 4 to inches long, and calyx-lobes in the 

 Texan plant becoming almost half inch long. 



* * Corolla nearly naked at the throat, but obscurely puberulent and thickened under each lobe: 

 inflorescence dense and very foliose. 



I_i. pilosum, Nutt. Soft-hirsute and pubescent, pale or canescent : stems numerous from 

 a stout root, a foot high, strict, mostly simple, very leafy : leaves linear and linear-lanceo- 

 late, 2 to 4 inches long, mostly tapering from near the base to apex ; the lateral ribs or 

 veins obscure : flowers densely crowded in a leafy thyrsus : corolla campanulate-funnel- 

 form, almost half an inch long, silky outside, dull greenish-yellow : style slender : nutlets 

 broadly ovate, acute, smooth and polished, 2 to 2 lines long. Nutt. in Jour. Acad.

 ders of California. 



3. BATSCHIA, Endl. (Puccoov.) Perennials, with long and deep red 

 roots (filled with dyeing matter), very leafy stems, and mostly showy flowers: 

 corolla yellow, much exceeding the calyx (except in cleistogenous or depauperate 

 blossoms), more or less appressed-pubescent outside; the lobes commonly undulate 

 or crenulate and sinuses plicate-infolded': pubescent crests in the throat apparent: 

 stigma capitate 2-lobed : nutlets white, smooth and polished, the inner face rather 

 conspicuously carinate. Batschia, Gmelin. 



* Corolla light yellow, rather small; later floral I'-nvcs reduced to bracts, not surpassing the calyx. 

 L. multiflorum, Torr. Minutely strigose-hispid : steins virgate, often paniculate at sum- 

 mit, a foot or two high : leaves linear or linear-lanceolate : flowers numerous, short-pedicelled, 

 the later spicate : corolla narrow (5 or 6 lines long), with very short rounded lobes and 

 tube fully twice the length of the calyx ; the crests or folds in the throat inconspicuous. 

 Watson, Bot. King, 238 (remark) ; Gray, Proc. Am. Acad. x. 51. L. pilosum, Gray in Am. 

 Jour. Sci. ser. 2, xxxiv. 2-30, not Nutt. Lower Rocky Mountains, Colorado to Arizona 

 and W. Texas. Expanded limb of corolla 5-cleft, the minutely undulate rounded lobes 

 only a line and a half long : ring at base of the tube sparingly bearded. Anthers in all 

 known specimens inserted high in the throat and the style only half the length of the 

 corolla ; but a counterpart form may be expected. 



* * Corolla bright and deep yellow or orange ; the tube from one half to twice longer than the 

 calyx, and the crests at the throat little if at all projecting or arching; the lobes barely undulate 

 or entire : floral leaves or foliaceous bracts large, much surpassing the calvx. (Dimorphism as to 

 height of insertion of stamens and length of style manifest.) 



L. Calif ornicum, Gray. Soft-hirsute, a foot high : leaves lanceolate or oblong : corolla 

 hardly an inch long; its proper tube hardly twice the length of the calyx ; its funnelform 

 throat considerably longer than the very short lobes, almost destitute of crests ; the glan- 

 dular ring at base of the tube inconspicuous and naked. --Proc. Am. Acad. 1. c., & Bot. 

 Calif, i. 522. L. canescens, Torr. in Pacif. II. Rep. iv. 124, not Lelnn. California, in 

 Nevada and Plumas Counties, Bigelow, Lemmon, Mrs. Austin. Short-styled and high-sta- 

 mened form only known. 



L. Canescens, Leam. (Puccoox of the Indians.) More or less canescent when young: 

 stem hirsute, a span to a foot or more high : leaves oblong-linear or the upper varying to 

 ovate-oblong, mostly obtuse, softly silky-pubescent, greener with age but not rough : corolla 

 orange-yellow, with rather ample deeply 5-cleft limb, prominent crests in the throat, and 

 glandular ring at the base naked : flowers nearly sessile. Gray, Proc. 1. c. L. canescens, 

 & L.sericeum, Lehm. Asper. 305, 306. Batschia canescens, Michx. Fl. i. 130, t. 14 ; Barton, Fl. 

 Am. Sept. t. 58. Anchnsa cane.sccns, Mulil. Cat. Plains and open woods, in sandy soil, 

 Upper Canada and Saskatchewan to Alabama, New Mexico, and Arizona. Tube of the 

 corolla 3 or 4 lines long; the well-developed limb about half an inch in diameter ; in one 

 form style about the length of the tube and stamens, inserted below its middle. To this 

 species also belongs L. sericeum, Lehm., but not Anchnsa Viryinica, L., which as to the Lin- 

 naean herbarium is not identified, as to the plant of Clayton's herb, is an Onosmodium, as to 

 Morison's is probably L. hirtinn, and as to Plukenet's may be either of the Puccoons.
