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

 short-toothed or subeutire, uot definitely lobed. — Vera Cruz, San 

 Miguel del Soldado, alt. 1,850 m., April 20, 1899 (C. G. Prinyle, no. 

 7800). 



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

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



4 to 7 cm. long, 1 to 2 cm. wide, on slender petioles 1 to 2 cm, 

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

 puberulent beneath : inflorescences on short (1 dm. or les.s) leafy fulvous- 

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

 dant at the naked tip ; pedicels 3 to 7 mm. long, jointed below the very 

 slender neck (3 mm. long) of the calyx : tubular-campanulate calyx 

 broadened above, 1.5 to 2 cm. long, glabrous", conspicuously nerved, with 



5 (or 6) unequal deltoid acute ciliate lobes 4 mm. or less in length : 

 corolla 2.5 to 3 cm. long, the yellow tube slender, slightly 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. C. Smith, no. 343). 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 

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

 to oblong-elliptic, acutish, including the short petiole 4 to 6 cm. long, 



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

 sparingly bracteate flexuous or drooping long-peduncled racemes 4 to 

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

 the glabrous campanulate shallowly 5-cleft calyx (in anthesis 4 to 5 mm. 

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



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

 limb with 5 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, 18G5 or 18G6 

 {Bourgeau, no. 57) : Oaxaca, Mts. southeast of Miahuatlan, alt. 2,950 

 to 3,235 m., 1895 {E. W. Nelson, no. 2525). This is perhaps C. pedun- 

 culm-e, 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 : 

 stems decumbent at base. 1 to 2.5 dm. high, slender, very leafy, pilose in 

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