ADDITIONS AND CORRECTIONS. 617 



oblong-lanceolate, shorter than the disk, rather obtuse, extremely glandular : rays 

 20 or more, forming two series, with cuneate 3-lobed deep orange-yellow ligules : 

 disk-flowers about as many, most of them fertile : chaff of the tiattish receptacle 

 only between the ray and disk flowers, of linear and nearly distinct scales : pappus 

 of the disk-akenes of 5 to 8 ovate or roundish blunt and entire scales, which are 

 hairy on the back and margin. Proc. Am. Acad. xi. 79. 



On the Fort Yuma road, at Larkens, 80 miles east of San Diego, Palmer. A striking species 

 of the Hartmannin section, in some respects resembling H. frutesccns, to be inserted in the subdi- 

 vision (with some emendation) which includes H. angustifdlia and H. corymbosa. 



ll a . H. Wheeleri, Gray. Loosely branched from the base, slender, a span to a 

 foot high, somewhat hirsute, hardly at all glandular : leaves all linear and entire, 

 scattered (the lower an inch or two long) : heads scattered, short-ped uncled : scales 

 of the involucre lanceolate, herbaceous, rather short : rays only 5 or 6, bright yel- 

 low : disk-flowers numerous (yellow), with abortive ovary and no pappus : outer 

 chaff of the receptacle of distinct thin scales ; inner mostly wanting : fertile akenes 

 triangular. 



Tulare Co., Monachay Meadows, &c., upper part of South Fork of Kern River, at 8,200 to 

 10,000 feet altitude, Roihrock in Wheeler's Expedition, 1875. Head barely 3 lines high : rays 2 

 lines long and wide. Smooth akenes a line and a quarter long. A well-marked species of the Eu-

Head homogamous ; the rather numerous flowers all alike, perfect and tubular. 

 Scales of the involucre 6 to 12, more or less imbricated, obovate or oval, flat, thin, 

 often partly scarious or colored (whitish, rarely purplish). Receptacle small, naked. 

 Corolla with a narrow and glandular tube, abruptly dilated into a campanulate 

 throat, and with 5 revolute lobes. Style-branches rather broad and obtuse. Akenes 

 turbinate or inversely pyramidal, with a short stalk-like base. Pappus of 8 or 10 

 short and blunt silvery-scarious scales, nearly or quite nerveless. Biennial or 

 rarely perennial herbs (all N. American), whitened with a rather deciduous wool ; 

 the stems with a solitary or corymbose head of whitish or yellow flowers. 



1. H. luteus, Xutt. A span to a foot high : leaves mainly in a tuft at the 

 root, twice pinnately divided ; the lobes narrowly linear with revolute margins or 

 nearly liliform : stem scape-like, bearing few or rarely solitary long-peduncled heads 

 of light yellow flowers ; akenes very villous, at least on the angles : pappus nearly 

 as long as the tube of the corolla. Torr. & Gray, Fl. ii. 373. 



Tantillas Mountains, near the State line, in Lower California, Dr. Palmer. Extends eastward 

 to the Rocky Mountains.

1. P. papposa, Gray, var. epapposa. A depauperate short-peduncled form, 

 collected by Dr. Palmer, about half-way between San Diego and Fort Yuma (also 

 in S. Utah and Arizona) : some of the specimens with the normal barbellate- bristly 

 pappus to the disk-flowers, the others with a mere vestige or none.

3. T. canum, T). C. Eaton. A span high or more, in tufts from a woody base, 

 silvery-canescent : flowering stems simple, terminated by one or two or several corym-
