ESCHSCHOLTZlA GLAUCA Ge. 



"Perennial, very glaucous, erect, 2-4 

 ft. high, of a loosely cymose and some- 

 times distinctly dichotomous inflor- 

 escence: leaves small, their segments 

 linear and little divergent; torus with 

 a narrow but manifest spreading- rim: 

 petals an inch long, with orange spot 

 at base and commonly a narrow border 

 of the same color at the truncate sum- 

 mit, otherwise light yellow: seeds glo- 

 bular, reticulated: cotyledons linear, 

 cleft to the middle. On dry clayey hill- 

 sides of the interior basin of Santa 

 Cruz Island." — Greene, Pittonia 1:45 

 (Mr 1887). 

 ESCHSCHOLTZIA MARIT1MA Ge. 



"Root perennial: stems stout and 

 succulent, very leafy and dichotomous, 

 2-3 ft. long, wholly prostrate: herbage 

 very glaucous and also white-puberu- 

 lent: leaves dense, i. e., the spatulate- 

 oblong obtuse segments numerous, 

 short and crowded: torus with mani- 

 fest rim spreading horizontally: calyp- 

 tra about % inch long, oval, abruptly 

 narrowed to a very short blunt or even 

 retuse tip: corolla broad-campanulate; 

 petals 10 lines long, lemon-yellow with 

 a rhomboidal spot of orange at base: 

 pod small: seed reticulate. About 

 Point Harris on the northeastern part 

 of the island of San Miguel, on clayey 

 slopes near the sea; very plentiful." —

 ARABIS PARISHII Wat. 



"Low and cespitose (2-4 in. high), 

 very stellate-pubescent throughout, 

 the simple slender stems from a much 

 branched caudex: leaves entire, the 

 lower numerous, linear-oblanceolate, 6 

 lines long or less, the cauline few, lin- 

 ear, not articulate: fls rose-color, 3 or 

 4 lines long: pods glabrous, ascending 

 on pedicels 2 or 3 lines long (including 

 the elongated filiform style) by a line 

 broad, attenuate above; valves 1- 

 nerved and veined: seeds somewhat 

 2-rowed, elliptical, narrowly winged. 

 In Bear valley, San, Bernardino mts., 

 Cal., at 6,500 ft. alt. (Parish)."— Am

ARABIS PULCHRA Jones, 



"Perennial, canescent throughout 

 with a fine stellate pubescence, the 

 stems erect (a ft. high) from a branch- 



ing woody base: leaves entire, not ros- 

 ulate at base nor auriculate, the lower 

 narrowly oblaneeolate (1 or 2 in. long), 

 the upper linear-lanceolate: fis usual- 

 ly large (3-7 lines long), and deep rose- 

 color, soon spreading or reflexed: pods 

 pendent on pedicels 3 or 4 lines long, 

 finely pubescent, 1^-2% in. long by 1% 

 lines wide, the valves 1-nerved and 

 velined, and stigma sessile: seeds 

 small, in 2 rows, orbicular, winged."

 ARABIS PERENNANS Wat. 



"Perennial, with a usually branching 

 and somewhat woody base, roughly 

 stellate-pubescent or sometimes* gla- 

 brous above, about a foot high: lower 

 leaves broadly spatulate to narrowly 

 oblaneeolate, dentate or sinuate, the 

 petioles sometimes ciliate, the cauline 

 linear-oblong, auriculate, mostly en- 

 tire, fls small, often pale: pods divari- 

 cately spreading or reflexed, usually 

 curved, glabrous, 1 or 2 in. long by a 

 line broad or less, obtuse or acutish, 

 the small stigma sessile: .seeds orbicu- 

 lar, very narrowly margined." — S.

ARABIS BECKWITHI1 Wat. 



"Resembling A. subpinnatifida, bien- 

 nial, hoary with a fine dense stellate 

 pubescence: stem erect, a span high: 

 leaves entire, an inch long or less, the 

 radical oblaneeolate, the cauline lan- 

 ceolate, auriiculate: fls rose-color, 3-6 

 lines long: pods 8 glabrous (or slightly 

 pubescent when young), spreading 

 and arcuate, 2% in. long by a line 

 wide, acutish, the stigma sessile: seeds 

 broadly elliptical." — Am ac pr 22:467.

THYSANOCARPUS CONCHULIFERUS 

 "Glabrous and glaucous, 3-10 inches 

 high, rather stout and branching: up- 

 permost leaves remotely toothed, the 

 middle and lower as remotely linear- 

 lobed (the lobes straight and divari- 

 cate), all except the lowest auriculate- 

 clasping: racemes short and dense: 

 petals spatulate-oblong, nearly iy 2
