6. Cathartolinum macrosepalum Small, sp. nov. 



Perennial or perhaps sometimes annual, glabrous, bright-green, the stems solitary or 

 often sparingly tufted, 2.5-9 dm. tall, sparingly corymbosely branched above, with the 

 branches rather stiffly ascending, striate ; leaves erect-ascending or appressed, alternate, 

 except near the base of the stem, the blades thickish, linear-subulate to subulate, or nar- 

 rowly linear or linear-spatulate near the base of the stem, mainly 1-1.5 cm. long, acumi- 

 nate, entire, equally green on both sides ; bracts entire ; sepals manifestly unequal, the outer 

 lanceolate or oblong-lanceolate, 4-4.5 mm. long at maturity, acuminate, entire or nearly so, 

 the inner lanceolate to elliptic-lanceolate, shorter than the outer, slenderly acuminate, 

 rather copiously glandular-toothed ; petals yellow; capsules ovoid, 2-2.5 mm. broad, much 

 surpassed by the sepals.

Linum neo-mexicanum Greene, Bot. Gaz. 6: 183. 1881. 



Perennial, or sometimes annual or biennial (?), glabrous, commonly somewhat glaucous, 

 the stems simple, or commonly branched at the base or near it, the branches erect or nearly 

 so, 2-4 dm. tall, angled, virgate and simple or fastigiate, the cymes elongate and raceme- 

 like ; leaves erect or erect-ascending, numerous and approximate or crowded near the 

 base of the stem or branches, more distant above, mostly alternate, the blades oblong to 

 oblong-oblanceolate and less than 1 cm. long near the base of the plant, linear or nearly so 

 and longer above, entire, acute, sessile ; bracts mostly subulate ; outer sepals lanceolate, 

 4-5 mm. long at maturity, slightly acuminate, entire or with few and scattered glandular 

 teeth ; inner sepals shorter and broader than the outer, lanceolate or ovate-lanceolate, with 

 many firm glandular teeth ; petals yellow ; filaments linear-lanceolate ; capsules ovoid, 

 3-3.5 mm. long.

S. Cathartolinum sedoides (Porter) Small. 



Linum Kingii sedoides Porter, Rep. TJ. S. Geol. Surv. Terr. 4 : 474. 1871. 

 Linum Kingii pineiorum Jones. Proc. Calif. Acad. II. S : 628. 1895. 



Perennial and similar to L. Kingii in habit, but smaller and more compact, the stems 

 or branches mostly less than 1 dm. long ; leaves verv numerous, approximate on the flower- 

 ing branches, erect or ascending and more or less imbricated, the blades very thick, clavate 

 on the lower part of the stems, short-linear above, mainly 3-9 mm. long, entire; bracts 

 entire; flowers borne in fastigiate raceme-like cymes ; outer sepals ovate, becoming about 

 4 mm. long, with few glandular teeth, obtuse or acute; inner sepals shorter and broader 

 than the outer, closely glandular-toothed, obtuse or merely acute ; petals yellow ; capsules 

 ovoid, 3 mm. long; seeds about 2 mm. long.

9. Cathartolinum Kingii (S. Wats.) Small. 



Linum Kingii S. Wats. Bot. King's Expl. 49. 1871. 



Perennial with a woody base, glabrous, glaucous, the stems or branches more or less 

 tufted, 0.5-3 dm. tall, the flowering branches rather slender; leaves alternate, numerous, 

 rather spreading, quite approximate on the lower part of the flowering branches, more dis- 

 tant above ; blades thick, linear-spatulate below to linear above, mainly 1-2 cm. long, or 

 sometimes shorter, entire ; bracts entire ; flowers borne in fastigiate corymb-like cymes ; 

 outer sepals ovate, about 4 mm. long at maturity, sparingly glandular-toothed, acuminate ; 

 inner sepals shorter and broader than the outer, closely glandular-toothed, abruptly short- 

 pointed ; petals yellow; capsules ovoid, 4 mm. long; seeds nearly 3 mm. long.
