i"'' 1 BORAGINACEAE. 



filled in with ;i few short t r;nis\ erse rugae and many wart-like projections fitted 

 closely together, and so resembling a somewhat uneven cobble-stone pavement. — 

 (A. collina < Greene.) 



X.;ir Mt. Diablo, Brewer; San Joaquin plains. 



2. A. echinata Gray. Erect, V/o to 2y 2 ft. high, very hispid with white 

 spreading bristles; sepals very narrow, yellow-hispid; corolla light yellow, 

 about twice as long, little dilated at the throat, the limb 2 or 3 lines broad; 

 nutlets mnricate with slender points or almost prickly, not rugose. 



Plant of the Mohave Kegion, credited to Antioch. 



3. A. spectabilis F. & M. Erect, branching above, 1 to 2% ft. high, 

 with mostly linear or linear-lanceolate leaves; spikes 3 to 7 in. long; calyx- 

 lobes narrowly linear-lanceolate, reddish-hispid, % to % the length of the 

 corolla-tube ; corolla orange-yellow, 6 to 7 lines long with slightly unequal 

 lobes; nutlets somewhat flattened laterally, carinate dorsally and ventrally, 

 reticulate-rugulose and granulate. 



San Joaquin Valley; Southern California. 



4. A. intermedia F. & M. Buckthorn Weed. Erect, frequently widely 

 branched, \\U to 3 ft. high; stems and branches with scattered white bristles, 

 the foliage densely hispid-bristly with rather shorter bristles; inflorescence 

 hispid and with a short curly pubescence; leaves oblong-lanceolate to linear, 

 thickish, entire; racemes more or less crowded at the top of the stem or 

 branches and leafy-bracteate ; developed racemes 5 to 10 in. long, peduncled; 

 calyx-segments rusty-hispid, linear-acuminate, % as long as the narrow orange- 

 yellow corollas, in fruit twice as long at least as the nutlets; nutlets incurved, 

 carinate dorsally, scabrous-rugose and granulate, exceeding 1 line in length. 



Throughout our district, mostly towards the interior; frequently very 

 abundant in grain fields of the Sacramento Valley, forming rank thickets 3 

 to 4 ft. high. 



5. A. lycopsoides Lehm. Stems erect, branching, the branches at length 

 decumbent, 1 to 2 ft. long; herbage of a light yellowish green, setose-hispid; 

 leaves ovate-lanceolate or narrowly oblong, with erose-sinuate or entire margins; 

 racemes rather short, frequently leafy-bracteate; peduncles short or none; 

 calyx sparsely setose-hispid, the lobes lanceolate or ovate-oblong, obtuse, 2 or 

 :: of the lobes often united; corolla pale yellow, very slender; nutlets brown 

 or blackish, mnriculate and rugulose, scarcely more than % line long. 



Sandy soil along the seaboard: San Francisco. Apr.-May. 



6. A. grandiflora Kleeb. Robust, hispid, 1% ft. high; fully developed spikes 

 5 to 7 i?i. Long; calyx-segments fulvous-hirsute, often partly or wholly confluent 

 so as to appear as 3 or 4, in fruit 5 to 6 lines long; corolla 6 to 7 lines long, 

 deep yellow, with ample limb; anthers nearly sessile, inserted very low in the 

 corolla; outlets perfectly smooth, polished, light gray, carinate ventrally from 

 the apex to the nearly median oblong scar; lateral angles sharp, back concave. 



Antioch, Kellogg. The nearly related A. vernicosa H. & A. may be expected 

 within our limits southward; it has smaller flowers and sharply triquetrous nut- 

 resembling a grain of buckwheat) with very obscure scar. 



6. PECTOCARYA DC. 

 Low slender obscure annuals with Btrigose pubescence and narrowly linear 

 Leaves. Flowers minute, white, on very short pedicels, scattered along the stems or 

 branches. Calyx deeply 5-cleft, spreading of reflexed in fruit. Corolla with 

 a circle of processes or crests which almost close the throat. Stamens in- 

 eluded. Nutlets flat, thin, radiately divergent, bordered at apex or all around
