represented in Bot. Reg xxx. t. 43, but with the corolla limb merely 

 Bhort-toothed or subentire, not definitely lobed. — Vera Chuz, S;m 

 Miguel del Soldado, alt. 1,850 m., April 20, L899 (C. G. Princ/le, no. 

 7- 10). 



C. fulvescens. Branches stout; cortex yellowish brown, pruinose 

 or glabrate: leaves lanceolate or ovate-lanceolate, Bhort-acuminate, 

 •1 to 7 cm. long, 1 to 2 cm. wide, on Blender petioles 1 to 2 cm. 

 long, dark green and minutely puberulent above, yellow-green and 

 puberulent beneath : inflorescences on short < 1 dm. or less) leafy fulvous- 

 pubescent branches; the flowers in Bmall axillary clusters or more abun- 

 dant at the naked tip; pedicels d to 7 mm. long, jointed below the very 

 Blender neck (8 nun. long) of the calyx: tubular-campanulate calyx 

 broadened above, L.5 to 2 cm. long, glabrous, conspicuously nerved, with 

 •*) (or G) unequal deltoid acute ciliate lobes 1 mm. or less in length: 

 corolla 2.5 to 3 cm. long, the yellow tube slender, Blightbj exceeding the 

 calyx, clavate above and enlarged at the throat; limb of 5 (or 6) 

 elongate-lanceolate strongly involute ascending yellow-brown lobes, short- 

 pubescent especially within. — OaxACA, mountains of Telixtlahuaca, 

 alt. 2,000 m., Apr. 5, 1895 ( L. < '. Smith, no. 8 18). Apparently a mem- 

 ber of the section Habrothamnus, but with paler flowers than in any 

 described species of that section. 



C. Bourgeauianum. Branches slender, glabrous, covered with 

 i grayish brown cortex : leaves glabrous, entire, oblong-lanceolate 

 to oblong-elliptic, acutish, including the short petiole 4 to cm. long, 



1 to 2.5 cm. wide: inflorescence leafy-paniculate, of mostly compound 

 sparingly bracteate flexuous or drooping long-peduncled racemes 1 to 

 9 cm. long: pedicels slender, 3 to 9 mm. long, gradually thickened to 

 the glabrous campanulate shallowly 5-cleft calyx- (in anthesis 1 to 5 nun. 

 long. 2 to 3 mm. broad): corolla yellow, glabrous throughout, 1.7 to 



2 cm. long, narrowly funnelform below, gradually broadened at the throat ; 

 limb with •") generally broad-flaring somewhat rounded lobes nearly 

 0.5 cm. long: mature fruit nearly 1 cm. in diameter; calyx becoming as 

 broad as long. — Mexico, Valley of Mexico, June 12, 1865 or 1866 

 (Bourgeau, no. 57): Oaxaca, Mts. Boutheasl of Miahuatlan, alt. 2,950 

 to 3,2 35 m., L895 t E. W. Nelson, no. 2525). This is perhaps C. pedun- 

 culate, Pavon, but that species is described as having glandular reddish 

 branches, purplish- veined leaves, and acuminate corolla lobes. 



Aster jalapensis. Perennial from slender elongated rootstocks : 



is decumbent at base, 1 to 2.5 dm. high, Blender, very leafy, pilose in 



lines: leaves oblanceolate, bluntly and Bhortly acuminate, glabrous or
