Senecio ( Terminales) serraquitchensis Greenm. 



Suffruticose: stem above tawny-tomentose : leaves petiolate, 

 oblong-lanceolate to somewhat oblong-obovate, 1.2 to 2.5 dm. 

 long, 3 to 9 cm. broad, mucronate-acute, slightly sinuate, remotely 

 cartilaginous-denticulate, narrowed below to the tomentulose 

 2.5 to 6.5 cm.-long petiole, at first tomentulose on both surfaces 

 especially on the midrib and lateral nerves beneath, but soon 

 glabrate and rather strongly reticulate-veined: inflorescence 

 abruptly terminating the stem in one or more long-pedunculate 

 compound many-headed corymbs: heads about i cm. high, 

 radiate: involucre barely calyculate with minute bracteoles; 

 bracts of the involucre 8, narrowly oblong, about 4 mm. long, 

 obtuse, turning blackish in drying: ray-flowers 5; ligules short, 

 4-nerved; tube shorter than the pappus: disk-flowers 5 or 6; 

 corollas rather deeply 5-lobed: achenes glabrous. Monogr.

Senecio ( Terminales) uspantanensis Greenm. Monogr. Se- 

 necio, I Th. 26 (1901) & in Engl. Bot. Jahrb. xxxii. 22 (1902). 

 S. Ghiesbreghtii, var. uspantanensis Coulter, Bot. Gaz. xx. 52 

 (1895), in part, as to Heyde & Lux, no. 3,368 (hb. Gray) and 

 Botteri, nos. 609, 820 (hb. Gray). 



Although 5. uspantanensis is similar in habit to 5. serraquit- 

 chensis, yet the former differs markedly in its glabrous stem and 

 foliage, longer and fewer (5 instead of 8) involucral bracts. 



TRIXIS PRINGLEI Rob. & Greenm. Proc. Am. Acad. xl. 10 (1904). 

 Specimens collected by Professor C. Conzatti at De Almoloyas 

 Sta. Catarina, Oaxaca, Mexico, at an altitude of 1,000 m., 

 26 December, 1906, no. 1,646 (hb. Field Mus.) agree well with 

 specimens secured by Mr. Pringle on which the species was 

 based, except the leaves in the Conzatti plant have a maximum 

 breadth of 2.5 centimeters.

Stem terete, pubescent: leaves petiolate, orbicular-ovate, 

 cordate, 7-9-lobed, hirtellous-puberulent and rather strongly 

 reticulate-nerved above, crisp-hirsute-pubescent and atomi- 

 ferous-glandular beneath; lobes ovate-triangular, dentate, mu-
