Leucampyx* Newbeeeyi, Gray (Porter and Coulter in Fl. Colorado, p. 

 77). — Herbaceous, erect, 1-2° high, at first closely covered with a loose, fine 

 wool, but becoming almost glabrous later ; radical and lower stem-leaves 

 petioled (the bases of the petioles are dilated and somewhat sheathing), 

 bipinnately parted, the divisions linear, obtuse, and entire ; upper leaves 

 linear, entire, or remotely toothed; head (including rays) 2-2 J' in diameter; 

 scales of the involucre very woolly and somewhat exceeding the disk ; ray- 

 flowers yellow, fading into a " cream-color"; limb oblong or oval, and 

 sometimes toothed at the apex ; disk-flowers yellow ; achenia black. — 

 Western New Mexico, at 6,500 feet altitude, Loew. This rare plant was 

 also obtained in 1872 by Professor Porter at the " Soda Springs, 35 miles 

 northwest of Canon City", and a good description of it furnished in the 

 Flora of Colorado — Plate XII. Natural size. Fig. 1. Vertical section 

 through the receptacle, showing ray- and disk-flowers; also in volucral scale 

 and embracing chaff. 2. Single involucral scale. 3. Ray-flower. 4. Chaff 

 of the receptacle. 5. Disk-flower. 6. Style and stigma. All except the 

 branch enlarged about 7 diameters. 



Baileya multikadiata, Gray (PL Fendl. p. 105). — More or less 

 densely floccose-woolly, usually but little branched at the base ; leaves once 

 or twice pinnatifid; peduncles 4-12' long, and terminated by a large head 

 1 £-2' (including rays) across ; rays yellow, very many, in two ranks, 

 cuneate-oblong, somewhat sharply 3-toothed, £' long. — Camp Bowie, 

 Ariz. (495), and El Rito, N. Mex. (97). The Expedition has it also from 

 Nevada. 



Dr. Gray (PI. Fendl. p. 106) remarks of B. pleniradiata, " that the style 

 branches exhibit a more or less distinct central mucronation, or slight cone; 

 in the others [species] they are absolutely truncate." I find in the speci- 

 mens of pleniradiata from Southern Utah, collected by Dr. Parry, that this 



* Leucampyx, Gray. — Heads heterogamons, radiate ; rajs in one series, and, as also the disk- 

 flowers, fertile. Disk-flowers perfect. Involucre broadly hemispherical ; bracts 2-3 series, imbricated, 

 broadly scarious at the apex. Receptacle somewhat convex, chaff membranaceous-hyaline, partly 

 including the achenia. Tube of the ray-flowers Blender ; limb broad 3-toothed or 3-clefr. Disk-flowers 

 tubular, regular ; limb campanulate ; apex 5-cleft. Anthers obtuse at base, entire. Style-branches of 

 the disk-flowers at the apex short appendiculate, penicillate. Achenia cuneate, incurved, compressed on 

 the back, sub 3-angled, attenuate at base, obtuse at apex ; pappus none. — Benth. & Hook.
