 2 to 4 feet high, fe\v-lea\ ed or almost naked, puherulent i;i tlie 

 inflorescence: leaves mostly radical, teruate or biternate, then once 

 or twice pinnate; the segments ovate, lachiiately pinnatifid (^ to 

 1]4 inches long): umbel of numerous rays, with involucels of 

 several narrowly linear elongated bractlets; rays (fruiting) about 

 2 inches long; pedicels 2 to 4 lines long: fruit oval, 1 \A to 2 lines 

 long, with short conical stylopodia, and narrow acute ribs: oil- 

 tubes 8 to 5 in the intervals, 4 to 8 on the commissural side: seed 

 with round back and more or less deeply concave face, and a 

 prominent central longitudinal ridge. (Fig. 91.) — Cynapiinn

It is very evident, from a study of herbarium specimens, that this 

 species has been much misunderstood: for while we discover any number 

 of sheets labelled L. apiifolium, very few of them prove to be that species. 

 The small oval fruits, smaller than in any other species, with their narrow 

 ribs and reniform seed-section, easily separate it from other species. Its 

 range, apparently limited to the mountains of Oregon and N. California, 

 serves well to separate it trora the Colorado L. Hcopulorum, with which it 

 has been confounded. A form apparently near L. apiifolium was collected 

 by Henderson (no. ir)S8) at Oswego, (Oregon, May, 1887, and by Howell 

 (no. 121) near "Waldo. Oregon. The leaves are almost entirely wanting, 

 but the fruit is somewhat larger, the seed-face more deeply sulcate, and 

 and its central ridge wanting or nearly so.
