BORAGE FAMILY. ,345 



less 5-angled under the flowers, persistent. Calyx .1- parted to the base, indur- 

 ated and somewhat accrescent in fruit. Corolla white with yellow throat, sal- 

 verforni, with short tube; processes or crests in the throat none (?) or not 

 obvious. Nutlets ovate or lanceolate-ovate, smooth, rugose, tuberculate or even 

 with barbed or prickly points, often carinate on one or both sides. Scar of the 

 nutlet basal or above the base, concave or sometimes raised and stipe-like. 

 (Greek alios, diverse, and karua, nut, the plants separated from Cryptanthe on 

 account of the different fruits.)

1. A. mollis (Gray) Greene var. vestita Jepson. A rather rank plant with 

 many ascending branches 12 to 18 in. long or more; herbage very densely and 

 conspicuously hairy throughout even to the very calyces; spikes 3 to 6 in. long, 

 bractless; flowers about 2 lines broad; fruit not scattered; nutlets either light 

 or dark colored, exceeding y. 2 line, regularly reticulate on the back, carinate 

 from the apex to below the middle (the carina there vanishing in the meshes 

 of the reticulation) or not carinate, strongly ridged ventrally down to the 

 roundish scar, which is bounded toward the base by a horseshoe-shaped ridge. — 

 (A. vestita Greene.) 



Petaluma, Congdon, 1880; not since collected. 



2. A. chorisiana (Cham.) Greene. Diffuse (or at first erect) with reclining 

 branches 7 to 16 in. long, strigose throughout; radical leaves linear-elongated, 

 often 4 in. long; racemes elongated, at length very loose, leafy below; fruiting 

 pedicels about 3 lines long, seldom or never less than 1 line long; calyx little 

 accrescent, about 1 line long, the segments at length spreading; corolla 3 to 4 

 lines wide; nutlets ovate, % line long or a trifle more, dark brown, carinate 

 ventrally only, or also dorsally toward the apex, rugose and minutely granulate; 

 scar linear. — (Eritrichium chorisianum DC.) 



Low ground about San Francisco Bay: Vallejo; Belmont. Apr.-June. 



3. A. salina Jepson. Branched from the base, strictly erect and simple, 

 •j to o" in. high; rachis of the spikes fistulous-enlarged, the flowers rather dense, 

 but strictly unilateral in 2 rather marked rows; calyx-segments spatulate or 

 ovate, very strongly callous-thickened toward the base, the sinus next the 

 axis much deeper than the others, some of the outer sepals united nearly to the 

 summit in some cases; nutlets roughish papillate, with rather sharp lateral 

 angles, carinate dorsally.

4. A. stipitata Greene. Branched from the base and somewhat spread- 

 ing, the branches mostly simple, slender, commonly 9 to 12 in. long; leaves 

 linear-oblanceolate, 1 to 3 in. long, or the radical obovate or oblong, attenuate 

 into a long petiole; corolla 2 to 3 lines broad, white with yellow eye or the eye 

 changing to white; sepals at length brownish and often spreading; nutlets
