254 BOTANY. 



2-2i" long, 16-30-seeded; seeds transversely rugose, pitted. — Southern Cal- 

 ifornia, (Fremont, 350 Torrey ;) Western Arizona, (Ives, Cooper.)— Col- 

 lected in Southern Utah by Dr. Palmer, 1870. 



This species and the following, P. Ivesiana, have been referred by Dr. 

 Torrey in Ives' Report, as also some of the present new species in the notes 

 accompanying his determinations, to the section Conanthus, which was 

 founded by De CandoUe for the anomalous species Eutoca ? aretioides. But 

 that species, as will be seen, has as little affinity to these as to others of the 

 recognized Eutoca section and must still stand alone. There are characters, 

 however, belonging to this and the following species which will justify their 

 ranking as a section (Euglypta) distinct from Eutoca, viz : the united apisend- 

 ages and the transversely rugose seeds. The appendages are always pres- 

 ent, not free and distinct, but united to some extent over the lower part of 

 the filament and usually more or less adnate to it ; this, however, is Occa- 

 sionally the case in the section Phacelia. The transverse pitted ridges of 

 the seeds are strictly characteristic, but occur again in the genus Emmenanthe. 

 The filaments are also unequal and somewhat dilated downward, and the 

 capsule is mostly oblong and obtuse. 



Phacelia (Euglypta) Ivesiana, Torr Ives' Col. Exped., Bat. Rep. 

 21. Annual, 1-10' high, branched diffusely from the base, the branches 

 ascending,. pubescent and more or less glandular; leaves oblong or linear- 

 oblong, i-2' long including the petiole, pinnatifid, the segments 3-7 pairs, 

 oblong or obovate, entire or sparingly toothed or sometimes again pinnatifid, 

 obtuse ; racemes simple, 10-20-flowered, the flowers suberect on very short 

 pedicels ; sepals spatulate with a long narrow base, becoming 3-6" long ; 

 corolla about 2" long, white or pale-purple, tubular-campanulate, the tube 

 3 times longer than the rounded lobes, appendages attached to the dilated 

 and slightly adnate base of the filament ; stamens included, unequal ; style 

 often not exceeding the ovary, bifurcate at the summit; capsule oblong, 

 2-2^" long, acutish, obtuse, or emarginate ; seeds 16-24, strongly ridged 

 transversely, I" long or less. — Very near the last, from which it is hardly 

 distinguished but by the smaller and lighter-colored corolla. Western Ari- 

 zona, (Ives;) Southern Utah, (Palmer, 1870.) Dry foot-hills in Monitor, 

 Diamond, and Holmes' Creek Valleys, in the shade of Juniperus on the 

 Coyote and East Humboldt Mountains, Nevada, and on the shore of Stans- 

 bury Island, Utah ; 4,300-6,500 feet altitude ; June-September. (879.)
