BOERAGINACE^. (bOKRAGE FAMILY.; 85 



Var. grandiflora, Gr, Itobust, more hispid and large flowered, the limbs broader; 

 calyx lobes often combined, so as to appear as 3 or 4. 



3. ERITRICHIUM, Schr. 



Most obviously distinguished from Amslnckia and the nearer Echinospermiira by its 

 usually smaller white flowers, with shorter corolla tube. The species difficult of deter- 

 mination. 



1. E. Calif ornicum, DC The slender stems decumbent, a span or more long; 

 the leaves narrowly linear; stems flowering from near the base; flowers almost sessile, 

 mostly with leaves or bracts, at length scattered; the corolla only a line long; calyx open 

 in fruit. Passes into 



Var. subglochidiatum, Gr. Slightly succulent; lower leaves inclined to spatulate, 

 nutlets somewhat barbed. Wet ground. 



2. E. Scouleri, A.DC. Slender, erect a span to a foot high; leaves narrowly linear 

 (1 or 2 inches long); flowers in geminate or sometimes paniculate slender naked spikes, 

 most of them bractless; pedicels not more than a line long; calyx erect in fruit; corolla 

 Burpassing the calyx, the limb almost rotate, 2 to 5 lines in diametei". — Seems to pass 

 into the next. 



3. E. Cliorisianum, DC. At first erect, soon spreading or decumbent; larger leaves, 

 2 to 4 inches long; flowers in lax, usually solitary racemes, many of them leafy-bracted ; 

 pedicels sometimes filiform and 2 to 9 lines long; Corolla more funnel-form, its limb 3 

 to 5 lines in diameter, — This may be a wet ground form of the last, which grows on dry 

 ground. 



4. B. fulvum, A.DC. A span to a foot high, slender branched from a leafy base, 

 pubescent; leaves linear, or the lower lanceolate or spatulate; spikes at maturity nearly 

 filiform, bracteate only at the base; calyx, etc., densely clothed with rusty or fulvous 

 hairs; calyx deciduous, only the lower part remaining under the fruit; corolla limb 2 

 lines across. 



5. E. canescens, Gr. Stouter and larger than the last; the pubescence whitish, 

 not rusty; leaves linear; calyx hardly deciduous. 



6. E. osycaryum, Gr. May be known by the solitary ovate-acuminate, smooth, 

 Bhining nutlet enclosed in the persistent bur-like calyx; corolla 2 lines wide. 



4. ECHINOSPBRMUM, Swartz. 



Calyx lobes spreading or reflexed in fruit. Corolla short, salver-form, and with con- 

 spicuous arching crests at the throat. Short filaments, style, etc., as in Eritrichium. 

 Nutlets with barbed prickles. 



I. B. floribundiim, Lehm. Rather strict, 2 ft. or more high, or sometimes smaller; 

 leaves from oblong to linear-lanceolate; racemes numerous, usually geminate; the tri-
