 November, 1895, C. Conzatti, no. 30 (hb. Gr.). 



Sabazia (?) anomala, n. sp. Annual, 3 to 4.5 dm. high : stem dichot- 

 omously branched from near the base, pale green or purplish, hirsute- 

 pubescent with glandular hairs intermixed: leaves opposite, sessile, 

 ovate-lanceolate, 2 to 5 cm. long, 7 to 22 mm. broad, acute, remotely 

 and coarsely sinuate-dentate, cuneate to slightly rounded at the base, 

 pale green and hirsute-pubescent on both surfaces, 3-nerved from near 

 the base : peduncles terminating the stem and branches, 7 cm. or less 

 in length, hirsute-pubescent with glandular hairs intermixed : heads in- 

 cluding the fully expanded rays about 1.5 cm. in diameter: involucre 

 campanulate, 1-2-seriate; bracts of the involucre ovate to lance-ovate, 

 4 to 5 mm. long, acute or obtuse, herbaceous or somewhat tinged with 

 purple : receptacle conical, paleaceous ; pales narrow, trifid : ray-flowers 

 8, fertile ; rays white or roseate, obtusely 3-dentate : disk-flowers nu- 

 merous ; corollas yellow: pappus of both ray- and disk-flowers of 10 

 obovate or narrowly oblong ciliate-fringed persistent scales, half as long 

 as the achenes : mature achenes subterete, 1.5 mm. long, striate, rather 

 sparingly pubescent. — Mexico. State of Hidalgo: rocky mesas near 

 Buena Vista Station, altitude 2530 m., 7 August, 1904, G. G. Pringle, 

 no. 8853 (hb. Gr.). 



This species is placed doubtfully in the genus Sabazia, because of the 

 presence of a scaly pappus. In every other regard the plant is truly 

 congeneric, having a habit closely assimilating S. humilis, Cass., from 

 which it differs not only in the presence of a pappus but in the pubescent 

 shorter achenes. There is a superficial resemblance between Sabazia 

 anomala and Tridax trilobata, Hemsl. ; it is, however, a similarity in 

 habit and foliage rather than in technical or essential characters.

* Since tlie revision of this genus by Robinson and Greenman (Proc. Am. 

 Acad, xxxiv. 521-520, 1899) types of several of the earlier species have been 

 examined in the De Candolle herbarium by Dr. Robinson, and additional informa- 

 tion was obtained concerning their identity, especially that of P. buphthalmoides, 

 DC, which has been much confused with P. Cervantesii, DC. The above synonymy 

 and the specimens cited it is hoped may help to clear up the confusion of these two 

 species.
