Medina. Some of the specimens afterwards collected by Berlandier (distributed as Nos. 2562 
and 2573) connect this with the variety Drummondii, (Centauridium Drummondii, Torr. & 
Gray,) which has acute or cuspidate involucral scales. 
GRINDELIA SQUARROSA, Dunal.; var. GRANDIFLORA, Gray, Pl. Wright, 1, p. 98, etc. On the 
Manzanal, Texas, etc. It is No. 1921 of Berlandier’s collection. 
GRINDELIA LANCEOLATA, Nult.; Torr. & Gray, 1. c. Cobre, New Mexico; Thurber, Bigelow. 
Probably a mere variety of G. squarrosa. 
GRINDELIA ARGUTA, Schrader, in DC. l. с. Cobre cañon; Wright, Thurber. Probably this is 
likewise G. squarrosa. 
GRINDELIA INULOIDES, JVilld.; var. MICROCEPHALA.  G. microcephala, DC. Prodr. Southern 
and western Texas; Schott, Parry. This is the same as Berlandier’s plant, (No. 2057,) on 
which De Candolle founded his G. microcephala. The achenia are of the same shape as in G. 
inuloides ; but their thick walls are generally smooth and even, yet some of them show traces 
of the corky-rugose character of those of genuine G. inuloides. 
PENTACHAETA AUREA, Nutt. in Trans. Amer. Phil. Soc. Т, p. 336; Torr. Ё Gray, Fl. 2, p. 249, 
Var. 2. capitulis majoribus multiradiatis.—San Luis Rey ; February. Var. y. capitulis multo 
minoribus ; involucri squan;., plerumque obtusis; ligulis 7-10.— Cordilleras, near San Felipe, 
California, on the eastern slope; June. The first variety is a strong vernal form, with larger 
heads than in my specimens from Nuttall, yet agreeing very well with his description. The 
second is a later, much branched state, I believe, of the same species, although the heads are 
only one-third as large, the rays and the involucral scales proportionally fewer, and the latter 
either obtuse or retuse, or merely mucronate. The pappus of this occasionally consists of 6 or 
8 bristles. "The comparison of both forms with Nuttall's original specimens shows that they all 
belong to one species. 
BRADBURIA HIRTELLA, Torr. & Gray, Fl. 2, p. 250. Eagle Pass, etc., on the Rio Grande, 
Texas; Schott. | 
HETEROTHECA SCABRA, DC.; Torr. & Gray, 1. c. San Antonio to Presidio del Norte, etc.; 
Bigelow, Schott, Parry. Very tall specimens were gathered at Presidio by Dr. Bigelow, 
growing four feet high. 
HETEROTHECA FLORIBUNDA, Benth. Bot. Voy. Sulph. p. 24. Вап Luis Rey, California; October; 
Parry. This is certainly Bentham’s H. floribunda, and is the same as No. 275 of Coulter’s 
California collection, although the heads are somewhat larger. I fear it passes into H. grandi- 
flora, Nutt. 
CHRYSOPSIS CANESCENS, Torr. Ё Grate; ЕІ. 2, p. 256. On the Cibolo, Salado, and Limpio, 
Texas; Bigelow, Schott. 
CHRYSOPSIS VILLOSA, Nutt. San Estaban, New Mexico; Bigelow, 
CHRYSOPSIS FOLIOSA, Хий. New Mexico, northern Sonora, etc. This and C. hispida vary 
greatly in appearance, and are probably to be reduced to C. villosa. 
Curysopsts HISPIDA, Hook. Clefts of rocks between the San Pedro and Pecos; Bigelow. 
Curysopsis РПовА, Nutt. On the Rio Grande near Coleto creek ; Schott. 
LaPHAMIA HALIMIFOLIA, Gray, Pl. Wright, 1, p. 100, t. 9. Hills of the San Pedro; Wright, 
Bigelow. 
— 
— 
LAPHAMIA ANGUSTIFOLIA, Gray, l. c. High rocky hills of the Pecos, in crevices of the lime- —_ 
stone, and mountains near Live Oak creek ; Bigelow, Wright. Also between San Pedro and 
the Puercos ; Schott.
