BORRAGINACEH. (BORRAGE FAMILY.) 85 
Var. grandiflora, Gr. Robust, more hispid and large flowered, the limbs broader; 
ealyx lobes often combined, so as to appear as 8 or 4, 
3. ERITRICHIUM, Schr. 
Most obviously distinguished from Amsinckia and the nearer Echinospermum by its 
usually smaller white flowers, with shorter corolla tube. The species difficult of deter- 
mination. 
1. HE. Californicum, 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. HE. 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 
surpassing the calyx, the limb almost rotate, 2 to 5 lines in diameter.—Seems to pass 
into the next. 
3. H. Chorisianum, 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. HE. fulvum, A.DC. A span toa 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. HEH. oxycaryum, Gr. May be known by the solitary ovate-acuminate, smooth, 
shining nutlet enclosed in the persistent bur-like calyx; corolla 2 lines wide. 
4. ECHINOSPERMUM, 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., asin Eritrichium. 
Nutlets with barbed prickles. 
1. E. floribundum, Lehm. Rather strict, 2 ft. or more high, or sometimes smaller; 
leaves from oblong to linear-lanceolate; racemes numerous, usually geminate; the tri-
