6S SOUTHERN CALIFORNIA ACADEMY OF SCIENCES 



rootstocks somewhat lignescent, frequently 2-3dm. long; stems 

 1dm. high or less, the older ones slender and dichotomonsly 

 branched above, the younger ones stouter; leaves 3-7mm. long, 

 fascicled and oblong on the young shoots ; on the older 

 branches lanceolate, acute, opposite; . sepals 4-5mm. long, 

 lanceolate, acuminate, 3-veined, the midvein especially 

 prominent; petals white, slightly exceeding the calyx. 



No. 5892, collected on open, stony slopes near Summit Lake, 

 Mt. Sanhedrin, Lake county, July 15, 1902. It ia abundant, 

 growing in dense mats, often carpeting the ground in suitable 

 situations. In California, at least, it has passed for Arenaria 

 verna hirta. 



^ERIOGONUM SMALLIANUM. sp. nov. 



Perennial, the lignescent part of the stem gnarled and 

 prostrate, covered with brown, flaky bark, sometimes very 

 short, or sometimes a decimeter or more in length; stems of the 

 season with a maximum length of about 2dm., two or 

 occasionally umbellately branched above, clothed with a close 

 lanate pubescence ; leaves basal, obovate or obovate- 

 spatulate, the largest about 13mm. long, including the petiole of 

 2-3mm., densely covered with a, feltdike mat of hairs, especially 

 the lower side, which is white, the upper greenish ; umbels 

 simple, one to three rayed, the peduncles l-3cm. long ; involucres 

 calyx-like, densely, wooly, about 4mm. high, the short segments 

 barely acute ; flowers sulphur yellow with a midvein orange 

 or red, on slender pedicles of 1mm., the segments about 5mm. 

 long, 2 mm. wide, obovate, rounded, or sometimes acutish, the 

 stipitiform base about one-fourth the length of the segments. 



No. 5996, collected in open, stony ground, near the summit 

 of Mt. Sanhedrin, Lake county, July 28, 1902, and distributed 

 as E. croceum. Small but differing from that species in its 

 lower, more cespitose growth, denser pubescence, fewer and 

 more simple umbels on stouter peduncles, etc. E. croceum, 

 originally collected by Mrs. Heller and myself on the "breaks" 

 of the Salmon river, northern Idaho, probably does not occur 

 in California, although plants similar to our type of E. 

 Smallianum have been labeled as such. 



^y'- DELPHINIUM LUTEUM, sp. nov. 



About 3dm. high, somcAvhat branched; stems with very few 

 short hairs, purplish: leaves deep green, mostly basal, none 

 exceeding the inflorescence, the blade orbicular in outline, about
