BOKRAGINACE.E. (BORAGE FAMILY.) 263 



corolla, which is hairy near the base within. From Dakota and Wyoming 

 to New Mexico. 



Var. Pendleri, Gray. A commonly hirsute form, with calyx 5-cleft only 

 to the middle. Proc. Am. Acad. x. 52. 



* * Filaments narrower than the anthers, inserted either on the margin of the 



throat or about the middle of the tube : style included. 



5. M. alpina, Don. A span or more high, either nearly glabrous or pu- 

 bescent : leaves oblong, somewhat spatulate or lanceolate, rather obtuse ; the 

 cauline sessile (1 or 2 inches long): flowers in a close or at length loose 

 cluster : calyx-lobes equalling or rather shorter than the tube of the corolla : 

 anthers nearly sessile. High elevations in mountains of Colorado and Utah. 



7. MYOSOTIS, L. FORGET-ME-NOT. 



Low and spreading pubescent herbs, with sessile stem leaves and small blue 

 flowers in bractless racemes. In ours the calyx is beset with hairs, some of 

 them bristly and having minutely hooked tips. 



1. M. sylvatica, Hoffm. Hirsute-pubescent, either green or cinereous : 

 leaves oblong-linear or lanceolate ; the radical conspicuously petioled : pedicels 

 as long as the calyx or longer : calyx-lobes erect or slightly closing in fruit : 

 nutlets more or less margined and carinate ventrally at the apex. 



Var. alpestris, Koch. Stems tufted, 3 to 9 inches high : racemes more 

 dense : pedicels shorter and thicker, seldom longer than the calyx. In high 

 alpine regions in the mountains of Colorado and Wyoming, and northward. 



8. LITHOSPERMUM, Tourn. CROMWELL. 



Herbs with reddish roots, sessile leaves, and axillary or subaxillary or leafy- 

 bracted flowers: stamens with very short filaments, and nutlets (in ours) 

 white, smooth and polished. 



* Flowers rather small: corolla greenish-yellow, short; its tube hardly if at all 



longer than the calyx, nearly naked at the fhroat. 



1. L. pilosum, Nutt. Soft-hirsute and pubescent, pale or canescent: 

 stems numerous from a stout root, a foot high, mostly simple, very leafy : 

 leaves linear and linear-lanceolate, mostly tapering from near the base to 

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

 form, almost 4 inch long, silky outside. From British Columbia and Mon- 

 tana to Utah and California. 



* * Flowers mostly showy : corolla yellow, much exceeding the calyx ; pubescent 

 crests in the throat apparent. Plants with long and deep red roots (Puccoox). 



*- Corolla light yellow : later floral leaves reduced to bracts, not surpassing the 



calyx. 



2. L. nmltiflomm, Torr. Minutely strigose-hispid : stems virgate, a 

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

 pedicelled, the latter 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. In the mountains from Colorado to 

 Arizona and Texas.
